Page 5 GE Data Sheet CCR0512FP Power Supply 90 - 264Vac Input; 12Vdc, 500W Output Safety Considerations The CCR0512 power supply is intended for inclusion in other equipment and the user must ensure that it is in compliance with all the requirements of the end application. This product is only for inclusion within other equipment and must not be operated as a stand-alone product. Thermal Considerations The power supply can be operated in a variety of thermal environments; however sufficient cooling should be provided to ensure reliable operation. Considerations include ambient temperature, airflow, power supply dissipation and the need for increased reliability. A reduction in the operating temperature of the power supply will result in increased reliability. The thermal derating presented in Figures 2-6 is based on measurements taken in a wind tunnel. Feature Descriptions Standby Power Supply A standby output, VSB, in the CCR0512 power supply comes on when AC input in the operating range is applied. Remote Sense The power supply has both positive and negative remote sense connections that can be connected to the positive and negative rails of the main output near the load. Care should be taken in routing the sense lines to ensure that noise is not picked up or that additional filtering elements that affect the stability of the power supply are not used. The power supply will operate without the remote sense connections being made, however if remote sense near the load is not used it is recommended that the remote sense lines be connected directly to the main output terminals. Overcurrent Protection To provide protection in a fault condition (output overload), the power supply is equipped with internal current-limiting circuitry and can endure current limiting continuously. At the point of current-limit inception, the unit enters hiccup mode. The power supply operates normally once the output current is brought back into its specified range. Overvoltage Protection Overvoltage protection is a feature of the CCR0512 power supply that protects both the load and the power supply from an output overvoltage condition. When an overvoltage occurs, the power supply shuts down and latches off. It is necessary to recycle the input to restart the power supply when this protection is activated. Overtemperature Protection The CCR0512 also features overtemperature protection in order to provide additional protection in a fault condition. The power supply is equipped with a thermal shutdown circuit which detects excessive internal temperatures and shuts the unit down. In the event of an over temperature condition, the unit protects itself by providing a low warning signal for 10 seconds (typical) and then shutting off. Once the power August 12, 2014 supply goes into overtemperature shutdown, it will cool before attempting to restart. Input Undervoltage Lockout At input voltages below the input undervoltage lockout limit, power supply operation is disabled. The power supply will begin to operate at an input voltage above the undervoltage lockout turn-on threshold. DC OK The CCR0512 provides a DC OK signal that indicates when the output has come up and is in regulation. This is an opencollector type signal that goes high when the output is available and within regulation. Paralleling/Load Share This power supply can be paralleled to provide larger load currents than can be delivered from a single power supply. Up to four power supplies may be paralleled. Paralleling is accomplished by connecting the Current Share signals of multiple power supplies together. At load current levels above 20%, the output currents of multiple power supplies will be within 5% of the full load value. If remote sense is used when paralleling is employed, the remote sense connection points should be common to both power supplies. The supply is equipped with internal Or-ring mosfets in the + VOUT leg and designed for hot swap operation. Signal Considerations (Pin Number) Output Voltage Programming (D4)) Analog input signal - voltage determining the rectifier output voltage. VOUT = 10.8V+ (Vprog X 0.96)V, for Vprog from 0V to 2.5V VOUT = 13.2V, for Vprog from 2.5V to 3.0V VOUT = 12.0V, for Vprog higher than 3.0V or left open Output Current Monitoring (B3) Analog output signal. Voltage proportional to the power supply output current (0.1V/AMP) +/- 250mv. Load Share/Paralleling (C3) Analog signal. Single wire connection. Unit will load share within 5% of full load. Remote ON-OFF (E1) TTL compatible. Open collector (High) for normal operation. Sink current: 4mA. Max collector voltage: 12Vdc Logic 1 (TTL High) or open enables unit (ON); Logic 0 (TTL Low) or short shuts unit down (OFF). Cycling this signal resets the over-voltage protection memory. AC OK (E3) TTL compatible. Open collector (High) for normal operation. Sink current: 4mA. Max collector voltage: 12Vdc AC OK indicates that AC is applied within the specified input range for the rectifier. DC OK (E2) TTL compatible. Open collector (High) for normal operation.

Max collector voltage: 12Vdc Over Temperature Warning (C5) TTL compatible. Open collector (High) for normal operation. Sink current: 4mA. Max collector voltage: 12Vdc. In the event of an over temperature condition, the unit protects itself by providing a low warning signal for 10 seconds (typical) and then shutting off. Auto restart after the condition is cleared. Fault Signal (B2) TTL compatible. Open collector (High) for normal operation. Sink current: 4mA. Max collector voltage: 12Vdc This alarm is an opto-isolated open collector signal referenced to +VOUT Return or chassis ground. The signal indicates that a failure has been detected in the unit (OTP, OVP, AC Fail or No Input). Signal Return (A3) The signal return is the referenced for all the signals and is internally connected to the output return (+VOUT leg). Missing Module (B5) Binary signal delivered when the rectifier is present (active low, strap to return signal) Serial Bus Communications All signals are referenced to `Signal Return'. Device addressing: The microcontroller (MCU) and the EEPROM have the following addresses: Device Address Address Bit Assignments (Most to Least Significant) MCU 0xBx 1 0 1 1 A2 A1 A0 R/W Broadcast 0x00 0 0 0 0 0 0 0 0 EEPROM 0xAx 1 0 1 0 A2 A1 A0 R/W 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 internally. For logic LO connect to `Output Return'. Serial Clock (SCL): Clock pulses are host generated initiating communications across the IC Serial bus, and are 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. Serial Data (SDA): This is a bi-directional data line, 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. Basic Operation 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. Global broadcast: This is a powerful command because it instruct all power supplies to respond simultaneously. A read instruction should never be accessed globally. The power supply should issue an `invalid command' state if a `read' is attempted globally. For example, changing the `system' output voltage requires the global broadcast so that all paralleled power supplies change their output simultaneously. This command can also turn OFF the `main' output or turn ON the `main' output of all power supplies simultaneously. Unfortunately, this command does have a side effect. 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. 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. August 12, 2014 Clock Stretch Figure 13. 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 (c)2012 General Electric Company. All rights reserved. Page 7 GE Data Sheet CCR0512FP Power Supply 90 - 264Vac Input; 12Vdc, 500W Output 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, which should require validation to ensure that the correct command is executed. 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 receives a `clear' instruction as outlined below. If the alarm state is still present after the `clear_faults' command has been received, then the signal will revert back into its LO state again and will latch until a subsequent `clear_faults' signal is received from the host controller. The signal will be triggered for any state change, including the following conditions; * * * * * * * * VIN under or over voltage Vout under or over voltage IOUT over current Over Temperature warning or fault Communication error PEC error Invalid command Detected internal faults processors to update their data base so that successive reads provide fresh data. 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. PMBusTM Commands Standard instruction: Up to two bytes of data may follow an instruction depending on the required data content. Analog data is always transmitted as LSB followed by MSB. PEC is optional and includes the address and data fields. 1 S 8 Slave address 8 Low data byte 1 S * * * the STATUS_BYTE (0x78) or STATUS_WORD (0x79) are read Receiving a CLEAR_FAULTS command The main output recycled (turned OFF and then ON) via the REMOTE ON/OFF signal pin The main output recycled (turned OFF and then ON) by the OPERATION command 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. 1 A 8 Command Code 8 High data byte 1 A 1 A 8 PEC 1 A 1 P Master to Slave Slave to Master SMBUS annotations; S - Start , Wr - Write, Sr - re-Start, Rd - Read, A - Acknowledge, NA - not-acknowledged, P - Stop Standard READ: Up to two bytes of data may follow a READ request depending on the required data content. Analog data is always transmitted as LSB followed by MSB. PEC is mandatory and includes the address and data fields. PEC is optional and includes the address and data fields.

All standard PMBus values, with the exception of output voltage related functions, are represented by the linear format described below. Output voltage functions are represented by a 16 bit mantissa. Output voltage has a E=-9 constant exponent. The Linear Data Format is a two byte value with an 11-bit, two's complement mantissa and a 5-bit, two's complement exponent or scaling factor, its format is shown below.

There are no adjustments or read backs of the standby output. Failure of the standby output is reported by the STATUS_MFR_SPECIFIC register. The code does not check the validity of, or whether the data being changed is within the expected boundary. The user is responsible to make sure that data placed in the registers is within the monitored range. Command Descriptions Operation (01) : By default the Power supply is turned ON at power up as long as Power ON/OFF signal pin is active HI. 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 August 12, 2014 DATA BYTE 00 80 40 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. Preemptive 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. 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.
