Rated at 460 watts, the DS460S-3 power supply generates a main payload output of 12 Vdc and an auxiliary output of 12 Vdc for powering standby circuitry. These power supplies are digitally programmable - they are equipped with an I2C interface and use the industry-standard PMBusTM communications protocol. The DS460S-3 power supply is intended primarily for use in rack-mounting server type applications, such as data centers. The power supply uses an advanced power conversion topology to maximize efficiency and have exceptionally compact form factors; these models have a height of just 1.6 inches, which makes them ideal for use in 1U high rack-mounting equipment. DS460S-3 power supply features a wide 90 to 264 Vac input voltage range and employs active power factor correction to minimize input harmonic current distortion and to ensure compliance with the international EN61000-3-2 standard - they have a power factor of 0.99 typical. Safety UL/cUL 60950 (UL Recognized) NEMKO 60950 CB Certificate and report CE Mark (LVD) The supply has a 1U x 2U form factor - it measures only 7.75 inches in length, ideally suitable for length limited applications. When fed with a high line 230 Vac input, the DS460S-3 can achieve a very high - 92 percent typical conversion efficiency at 50 percent full load.

This product is only for inclusion by professional installers within other equipment and must not be operated as a stand alone product. The DS460S-3 series has been designed in accordance with EN60950-1 `Safety of Information Technology Equipment'. The series also conforms with the provisions of the European Council Low Voltage Directive 73/23/EEC (as amended by 93/68/EEC ) to bear the CE Mark. Note, appropriate safety certificates and approvals are available to download from our website www.powerconversion.com. Table 7.

The unit is enclosed inside a metal box, tested at 460W using resistive load with cooling fan. Conducted Emissions Table 8. Conducted EMI emission specifications of the DS460S-3 series Parameter Model Symbol Min Typ Max Unit FCC Part 15, class B All Margin - - 6 dB VCCI Class II All Margin - - 6 dB EN 60601-1-2: 2001 All Margin - - 6 dB CISPR 22 (EN55022) class B All Margin - - 6 dB Radiated Emissions Unlike conducted EMI, radiated EMI performance in a system environment may differ drastically from that in a stand-alone power supply. The shielding effect provided by the system enclosure may bring the EMI level from Class A to Class B. It is thus recommended that radiated EMI be evaluated in a system environment. The applicable standard is EN55022 Class A (FCC Part 15). Testing ac-dc convertors as a stand-alone component to the exact requirements of EN55022 can be difficult, because the standard calls for 1m leads to be attached to the input and outputs and aligned such as to maximize the disturbance. In such a set-up, it is possible to form a perfect dipole antenna that very few ac-dc convertors could pass. However, the standard also states that `an attempt should be made to maximize the disturbance consistent with the typical application by varying the configuration of the test sample'. Preliminary Power and Control Signal Descriptions Rev.10.06.28_#0.4 DS460S-3 Series Page 14 AC Input - IEC320 C14 This connector supplies the AC Mains to the DS460S-3 power supply. Pin 1 - Line Pin 2 - Neutral Pin 3 - Earth Ground Output Connector - Power Blades These Power Blades provide the main output for the DS460S-3. The Vo and the TRN blades are the positive and negative rails, respectively, of the main output of the DS460S-3 power supply. The RTN rail is electrically connected to the power supply chassis. PB1 - VO PB2 - VO PB3 - VO PB4 - RTN PB5 - RTN PB6 - RTN PB7 - RTN PB8 - RTN PB9 - VO PB10 - VO Control Connector - Signal Pins The DS460S-3 contains a 16 pins control signal header providing control signal interface and standby power interface. VSB (StandBy Voltage) - (S1 & S2 ) The DS460S-3 provides a regulated 12 volt 2.5 amp auxiliary output voltage to power critical circuitry that must remain active regardless of the on/off status of the power supply's main output. The VSB standby voltage is available whenever a valid AC input voltage is applied to the unit. The VSB output is independently short circuit protected and is referenced to the RTN pins (S15 & S16). PS INTERRUPT - (S4) The signal behavior in response to certain operating condition changes in the power supply as defined in the Firmware Specification section. This signal shall be pulled up to maximum 5V logic level external to the PS. Preliminary Rev.10.06.28_#0.4 DS460S-3 Series Page 15 PS PRESENT (Power Supply Present) - (S5) PS PRESENT signal is used to sense the number of power supplies in the system (operational or not) and provide hot plug insertion and removal functionality by controlling main outputs during hot plug insertion and removal by employing following circuitry. When the unit is removed from the system the fast shut down signal quickly turns OFF main outputs and discharges output capacitors. This signal is the shortest gold finger pin on the signal connector to allow for last make, first break configuration. Power Supply Side System Side 12V VSB 3.3V VSB 5.1K Ohm PS PRESENT Fast Shutdown + PS PRESENT 1.00K Ohm When the power supply is plugged into a system backplane, PS PRESENT is 0.54V +/-5% and the 12V output is enabled. When the power supply is removed, PS PRESENT on the power supply is ~0V and the 12V output is disabled. When the power supply is plugged into the system backplane, PS PRESENT is pulled low (0.54V +/-5%) indicating a power supply is present. When the power supply is removed from the system, PS PRESENT on the system side is pull up to 3.3V (system side standby) indicating that no power supply is present. Preliminary PSOK (Output OK Indicator) - (S6) Rev.10.06.28_#0.4 DS460S-3 Series Page 16 PSOK is a combined indicator of AC input and main 12V DC output. This is a three level signal to indicate different stages as follows. AC not OK and DC not OK - Signal status shall be LOW (<0.6V) AC OK and DC not OK - Signal status shall be LOW (<0.6V) AC OK and DC OK - Signal status shall be HIGH (> 3.0V) AC not OK and DC OK - Signal status shall be Middle Level (Between 2V and 2.5V) DC OK threshold is defined as when the 12V output is greater than 11.5V. DC not OK threshold is defined as when the 12V output is less than 11.4V and greater than 11.3V. I-Mon (Current Monitor) - (S7) I-Mon signal provides both the load sharing function (as a feedback for output regulation droop function) and 12V output current information. Signal characteristic is defined in below table. Preliminary PSON# (Power Supply ON) - (S8) Rev.10.06.28_#0.4 DS460S-3 Series Page 17 PSON# signal is required to remotely turn on/off the power supply. PSON# is an active low signal that turns on the main 12V DC output. When this signal is not pulled low by the system, or left open, the 12V output is turned off. This signal is pulled to a standby voltage by a pull-up resistor internal to the power supply. Refer to below On/Off Timing for timing diagram. When in off or standby condition, the main 12V DC output will be less than 50mV with respect to output return. SCL, SDA (I2C Serial Clock and Data) - (S9 & S10) I2C Serial Clock (SCL) signal and the Serial Data (SDA) signals are used to communicate power supply status with end use system as defined in the Firmware Specification section. Both pins are bi-directional and are used to form a serial I2C bus. These signals are pulled up to 5V logic level internal to the PS through separate 20K resistors. Capacitance on each signal internal to the Power Supply is less than 150pF. The end user system should also provide 3.3K to 10K pull-up resistors for the SDA and SCL lines to 5Vsb or an appropriate VCC derived from 12V VSB. If system side of the I2C Bus is pulled up to a voltage lower than 5V, then level shifting/isolation circuits must be placed between the PS side and the system side of the bus. GND (I2C Signal Ground) - (S11) Ground reference for I2C signals SCL and SDA ADD0, ADD1, ADD2 (PS Address lines A0, A1, A2) - (S12, S13 & S14) Address pins ADD0, ADD1 and ADD2 are used by end use system to allocate unit address to a power supply in particular slot position. These lines are pulled up to 5V logic level internal to the PS. The end user system must pull these lines low via 300 or less or leave it floating to assign the I2C address of the power supply. Power supply FRU device address is configured per the table below: Preliminary RTN (Output Return) - (S15 & S16) Power return for the standby voltage VSB, electrically connected to the main VO 12VDC output return RTN of the power blades.
