Page 6 GE Data Sheet CAR2512FP series rectifier Input: 90VAC to 264VAC; Output: 12 VDC @ 208A; 3.3VDC or 5 VDC @ 1A Control and Status Control hierarchy: Some features, such as output voltage, can be controlled both through hardware and firmware. For example, the output voltage is controlled both by the signal pin (Vprog) and the PMBus command, (Vout_command) . Using output voltage as an example; the Vprog signal pin has ultimate control of the output voltage until the Vprog is either > 3VDC or a no connect. When the programming signal via Vprog is either a no connect or > 3VDC, it is ignored, the output voltage is set at its nominal 12VDC and the unit output voltage can be controlled via the PMBus command, (Vout_command). Analog controls: Details of analog controls are provided in this data sheet under Signal Definitions. Common ground: All signals and outputs are referenced to Output return. These include `VSTDBY return' and `Signal return'. Control Signals Voltage programming (Vprog): An analog voltage on this signal can vary the output voltage 10% of nominal, from 10.8VDC to 13.2VDC. The equation of this signal is: VOUT = 10.8 (Vprog * 0.96) where Vprog = 0 to 2.5VDC Between 2.5 and 3V the output stays at 13.2VDC. If Vprog is > 3V, or left open, the programming signal is ignored and the unit output is set at the setpoint of 12VDC. Load share (Ishare): This is a single wire analog signal that is generated and acted upon automatically by power supplies connected in parallel. The Ishare pins should be tied together for power supplies if active current share among the power supplies is desired. No resistors or capacitors should get connected to this pin. Remote_ON/OFF: Controls presence of the 12VDC output voltage. This is an open collector, TTL level control signal that needs to be pulled HI externally through a resistor. A turn OFF command either through this signal (Remote ON/OFF) or firmware commanded would turn OFF the 12V output. Enable: This is a short signal pin that controls the presence of the 12VDC main output. This pin should be connected to `output return' on the system side of the output connector. The purpose of this pin is to ensure that the output turns ON after engagement of the power blades and turns OFF prior to disengagement of the power blades. Write protect (WP): This signal protects the contents of the EEPROM from accidental over writing. When left open the EEPROM is write protected. A LO (TTL compatible) permits writing to the EEPROM. This signal is pulled HI internally by the power supply. Status Signals Output current monitor (Imon): A voltage level proportional to the delivered output current is present on this pin. The signal level is 0.04V per amp 0.25V. April 23, 2013 Input_OK: A TTL compatible status signal representing whether the input voltage is within the anticipated range. This signal needs to be pulled HI externally through a resistor. DC_OK: A TTL compatible status signal representing whether the output voltage is present. This signal needs to be pulled HI externally through a resistor. Over_temp_warning: A TTL compatible status signal representing whether an over temperature exists. This signal needs to be pulled HI externally through a resistor. If an over temperature should occur, this signal would pull LO approximately 10 seconds prior to shutting down the power supply. The unit would restart if internal temperatures recover within normal operational levels. At that time the signal reverts back to its open collector (HI) state. Fault: A TTL compatible status signal representing whether a Fault occurred. This signal needs to be pulled HI externally through a resistor. This signal activates for OTP, OVP, OCP, INPUT fault or No output. PS_Present: This pin is connected to `output return' within the power supply. Its intent is to indicate to the system that a power supply is present. This signal may need to be pulled HI externally through a resistor. Interrupt (SMBAlert#): A TTL compatible status signal, representing the SMBusAlert# feature of the PMBus compatible i2C protocol in the power supply. This signal needs to be pulled HI externally through a resistor. Serial Bus Communications The IC interface facilitates the monitoring and control of various operating parameters within the unit and transmits these on demand over an industry standard IC Serial bus. All signals are referenced to `Signal Return'. Device addressing: The microcontroller (MCU) and the EEPROM have the following addresses: Device MCU Broadcast EEPROM Address 0xBx 0x00 0xAx 1 0 1 Address Bit Assignments (Most to Least Significant) 0 1 1 A2 A1 A0 R/W 0 0 0 0 0 0 0 0 1 0 A2 A1 A0 R/W The Global Broadcast instruction executes a simultaneous write instruction to all power supplies. A read instruction cannot be accessed globally. The three programmable address bits are the same for all I2C accessible devices within the power supply. Address lines (A2, A1, A0): These signal pins allow up to eight (8) modules to be addressed on a single IC bus. The pins are pulled HI internal to the power supply. For a logic LO these pins should be connected to `Output Return' Serial Clock (SCL): The clock pulses on this line are generated by the host that initiates communications across the IC Serial bus. This signal is pulled up internally to 3.3V by a 10k resistor. The end user should add additional pull up resistance as necessary to ensure that rise and fall time timing and the (c)2013 General Electric Company. All rights reserved. Page 7 GE Data Sheet CAR2512FP series rectifier Input: 90VAC to 264VAC; Output: 12 VDC @ 2500W; 3.3VDC or 5 VDC @ 1A maximum sink current is in compliance to the IC specifications. Serial Data (SDA): This line is a bi-directional data line. . This signal is pulled up internally to 3.3V by a 10k resistor. The end user should add additional pull up resistance as necessary to ensure that rise and fall time timing and the maximum sink current is in compliance to the IC specifications. Digital Feature Descriptions PMBusTM compliance: The power supply is fully compliant to the Power Management Bus (PMBusTM) rev1.2 requirements. Manufacturer specific commands located between addresses 0xD0 to 0xEF provide instructions that either do not exist in the general PMBus specification or make the communication interface simpler and more efficient. Master/Slave: The `host controller' is always the MASTER. Power supplies are always SLAVES. SLAVES cannot initiate communications or toggle the Clock. SLAVES also must respond expeditiously at the command of the MASTER as required by the clock pulses generated by the MASTER. Clock stretching: The `slave' Controller inside the power supply may initiate clock stretching if it is busy and it desires to delay the initiation of any further communications. During the clock stretch the `slave' may keep the clock LO until it is ready to receive further instructions from the host controller. The maximum clock stretch interval is 25ms. The host controller needs to recognize this clock stretching, and refrain from issuing the next clock signal, until the clock line is released, or it needs to delay the next clock pulse beyond the clock stretch interval of the power supply. Note that clock stretching can only be performed after completion of transmission of the 9th ACK bit, the exception being the START command. PEC is a CRC-8 error-checking byte, based on the polynomial C(x) = x8 + x2 + x + 1, in compliance with PMBusTM requirements. The calculation is based in all message bytes, including the originating write address and command bytes preceding read instructions. The PEC is appended to the message by the device that supplied the last byte. SMBAlert#: The C driven SMBAlert# signal informs the `master/host' controller that either a STATE or ALARM change has occurred. Normally this signal is HI. The signal will change to its LO level if the power supply has changed states and the signal will be latched LO until the power supply either receives a `clear' instruction as outlined below or executes a READ STATUS_WORD. If the alarm state is still present after the STATUS registers were reset, then the signal will revert back into its LO state again and will latch until a subsequent reset signal is received from the host controller. The signal will be triggered for any state change, including the following conditions; The power supply will clear the SMBusAlert# signal (release the signal to its HI state) upon the following events: Clock Stretch Figure 1. Example waveforms showing clock stretching. IC Bus Lock-Up detection: The device will abort any transaction and drop off the bus if it detects the bus being held low for more than 35ms. Communications speed: Both 100kHz and 400kHz clock rates are supported. The power supplies default to the 100kHz clock rate. The minimum clock speed specified by SMBus is 10 kHz. Packet Error Checking (PEC): Although the power supply will respond to commands with or without the trailing PEC, it is highly recommended that PEC be used in all communications. The integrity of communications is compromised if packet error correction is not employed. There are many functional features, including turning OFF the main output, that should require validation to ensure that the correct command is executed. April 23, 2013 VIN under or over voltage Vout under or over voltage IOUT over current Over Temperature warning or fault Fan Failure Communication error PEC error Invalid command Detected internal faults Receiving a CLEAR_FAULTS command The main output recycled (turned OFF and then ON) via the ENABLE signal pin The main output recycled (turned OFF and then ON) by the OPERATION command Execution of a READ of the STATUS_WORD register Global broadcast: This is a powerful command because it can instruct all power supplies to respond simultaneously in one command. But it does have a serious disadvantage. Only a single power supply needs to pull down the ninth acknowledge bit. To be certain that each power supply responded to the global instruction, a READ instruction should be executed to each power supply to verify that the command properly executed. The GLOBAL BROADCAST command should only be executed for write instructions to slave devices. Read back delay: The power supply issues the SMBAlert # notification as soon as the first state change occurred. During an event a number of different states can be transitioned to before the final event occurs. If a read back is implemented rapidly by the host a successive SMBAlert# could be triggered by the transitioning state of the power supply. In order to avoid successive SMBAlert# s and read back and also to avoid reading a transitioning state, it is prudent to wait more than 2 seconds after the receipt of an SMBAlert# before executing a read back. This delay will ensure that only the final state of the power supply is captured. Successive read backs: Successive read backs to the power supply should not be attempted at intervals faster than every (c)2013 General Electric Company. All rights reserved.

The Operation command is used to turn the Power Supply ON or OFF via the PMBus. The data byte below follows the OPERATION command. FUNCTION Unit ON Unit OFF DATA BYTE 80 00 To RESET the power supply cycle the power supply OFF, wait at least 2 seconds, and then turn back ON. All alarms and shutdowns are cleared during a restart. Clear_faults (03): This command clears all STATUS and FAULT registers and resets the SMBAlert# line. If a fault still persists after the issuance of the clear_faults command the specific registers indicating the fault are reset and the SMBAlert# line is activated again. WRITE_PROTECT register (10): Used to control writing to the PMBus device. The intent of this command is to provide protection against accidental changes. All supported command parameters may have their parameters read, regardless of the write_protect settings. The contents of this register can be stored to non-volatile memory using the Store_default_code command. The default setting of this register is disable_all_writes except write_protect 0x80h. Vout_Command (21) : This command is used to change the output voltage of the power supply. Changing the output voltage should be performed simultaneously to all power supplies operating in parallel using the Global Address (Broadcast) feature. If only a single power supply is instructed to change its output, it may attempt to source all the required power which can cause either a power limit or shutdown condition. Software programming of output voltage permanently overrides the set point voltage configured by the Vprog signal pin. The program no longer looks at the `Vprog pin' and will not respond to any hardware voltage settings. If power is removed from the Controller it will reset itself into its default configuration looking at the Vprog signal for output voltage control. In many applications, the Vprog pin is used for setting initial conditions, if different that the factory setting. Software programming then takes over once I2C communications are established. To properly hot-plug a power supply into a live backplane, the system generated voltage should get re-configured into either the factory adjusted firmware level or the voltage level reconfigured by the margin pin. Otherwise, the voltage state of the plugged in power supply could be significantly different than the powered system. Vout_OV_warn_limit (42): OV_warning is extremely useful because it gives the system controller a heads up that the output voltage is drifting out of regulation and the power supply is close to shutting down. Pre-amative action may be taken before the power supply would shut down and potentially disable the system. OC and OT_fault_ response (47, 50): The default response for both OC and OT is auto_restart (hiccup). Each register, individually, can be reconfigured into a latched state. Latched and hiccup are the only supported states. Restart after a latch off: Either of four restart possibilities are available. The hardware pin Remote ON/OFF may be turned OFF and then ON. The unit may be commanded to restart via i2c through the Operation command by first turning OFF then turning ON . The third way to restart is to remove and reinsert the unit. The fourth way is to turn OFF and then turn ON ac power to the unit. The fifth way is by changing firmware from latch off to restart. Each of these commands must keep the power supply in the OFF state for at least 2 seconds, with the exception of changing to restart. A power system that is comprised of a number of power supplies could have difficulty restarting after a shutdown event because of the non-synchronized behavior of the individual power supplies. Implementing the latch-off mechanism permits a synchronized restart that guarantees the simultaneous restart of the entire system. A synchronous restart can be implemented by; 1. Issuing a GLOBAL OFF and then ON command to all power supplies, 2. Toggling Off and then ON the Remote ON/OFF signal 3. Removing and reapplying input commercial power to the entire system. FUNCTION Enable all writes Disable all writes except write_protect Disable all writes except write_protect and OPERATION DATA BYTE 00 80 40 April 23, 2013 (c)2013 General Electric Company. All rights reserved. The power supplies should be turned OFF for at least 20 - 30 seconds in order to discharge all internal bias supplies and reset the soft start circuitry of the individual power supplies. Page 11 GE Data Sheet CAR2512FP series rectifier Input: 90VAC to 264VAC; Output: 12 VDC @ 2500W; 3.3VDC or 5 VDC @ 1A Auto_restart: Auto-restart is the default configuration for recovering from over-current and over-temperature shutdowns. An overvoltage shutdown is followed by three attempted restarts, each restart delayed 1 second, within a 1 minute window. If within the 1 minute window three attempted restarts failed, the unit will latch OFF. If less than 3 shutdowns occur within the 1 minute window then the count for latch OFF resets and the 1 minute window starts all over again. Vin_UV_warn_limit (58): This is another warning flag indicating that the input voltage is decreasing dangerously close to the low input voltage shutdown level. Status_word (79): returns two bytes of information. The upper byte bit functionality is tabulated in the Status_word section. The lower byte bit functionality is identical to Status_byte. Fan_speed (D7): This register can be used to `read' the fan speed in adjustment percent (0 - 100%) or set the fan speed in adjustment percent (0 - 100%). The speed of the fan cannot be reduced below what the power supply requires for its operation. The register value is the percent number, it is not in linear format. Invalid commands or data: The power supply notifies the MASTER if a non-supported command has been sent or invalid data has been received. Notification is implemented by setting the appropriate STATUS and ALARM registers and setting the SMBAlert# flag. If a non-supported read is requested the power supply will return all 0x00h. Restart after a lachoff: To restart after a latch_off either of four restart mechanisms are available. The hardware pin Remote ON/OFF may be turned OFF and then ON. The unit may be commanded to restart via i2c through the Operation command by first turning OFF then turning ON . The third way to restart is to remove and reinsert the unit. The fourth way is to turn OFF and then turn ON ac power to the unit. The fifth way is by changing firmware from latch off to restart. Each of these commands must keep the power supply in the OFF state for at least 2 seconds, with the exception of changing to restart. A successful restart shall clear all alarm registers. A power system that is comprised of a number of power supplies could have difficulty restarting after a shutdown event because of the non-synchronized behavior of the individual power supplies. Implementing the latch-off mechanism permits a synchronized restart that guarantees the simultaneous restart of the entire system. Control and Read accuracy: The estimates below are believed to be reasonable under most operating conditions. However, these are typical numbers and not hard bound values that cannot be exceeded. In most nominal operating conditions the returned values are significantly better than these estimates.

A separate EEPROM IC, with write protect features, provides another 128 bytes of memory. Minimum information to be included in this separate EEPROM: model number, revision, date code, serial number etc. LEDs Two LEDs are located on the front faceplate. The INPUT OK LED provides visual indication of the INPUT signal function. When the LED is ON GREEN the power supply input is within normal design limits. The second LED DC/FLT provides visual indication of three different states of the power supply. When the LED is GREEN then there are no faults and the DC output is present. When the LED is AMBER then a fault condition exists but the power supply still provides output power. When the LED is RED then a fault condition exists and the power supply does not provide output power. A synchronous restart can be implemented by; 1. Issuing a GLOBAL OFF and then ON command to all power supplies, 2. Toggling Off and then ON the Remote ON/OFF signal 3. Removing and reapplying input commercial power to the entire system. It is good practice to turn OFF the power supplies for about 20 - 30 seconds in order to discharge all internal bias supplies and reset the soft start circuitry of the individual power supplies.
