All outputs are measured with reference to the return remote sense (ReturnS) signal. The +5V,+3.3V, +12V, -5V,-12V and +5VSB outputs are measure at the power supply connectors references to ReturnS. The +5V and +3.3V is measured at its remote sense signal (+5VS, +3.3VS) located at the signal connector.

The output voltages must rise from 10% to within regulation limits (Tvout_rise) within 5 to 70mS. The +5V, +3.3V and +12V output voltages should start to rise at about the same time. All outputs must rise monotonically. The +5V output needs to be greater than the +3.3V output during any point of the voltage rise. The +5V output must never be greater than the +3.3V output by more than 2.25V. Each output voltage shall reach regulation within 50 mS (Tvout_on) of each other during turn on of the power supply. Each output voltage shall fall out of regulation within 400 mS (Tvout_off) of each other during turn off. Figure 1 and figure 2 show the turn On and turn Off timing requirement. In Figure 2, the timing is shown with both AC and 4 PSON# controlling the On/Off of the power supply.

PSON# is an active low signal that turns on the +5V, +3.3V, +12V,-5V and –12V power rails. When this signal is not pulled low by the system, or left open, the outputs (except the +5VSB and V bias) turn off. This signal is pulled to a standby voltage by a pull-up resistor internal to the power supply. Signal Type Accepts an open collector/drain input from the system. Pull-up to VSB located in power supply. PSON# = Low Power ON PSON# = High Power OFF Table 6 – PWOK Signal Characteristic 3.5 Efficiency The efficiency is ʁ 74% at full loading condition to help reduce system power consumption at typical system loading conditions. . 3.6 +5VSB (Standby) The +5VSB output is always on (+5V Standby) when AC power is applied and power switch is turned on. The +5VSB line is capable of delivering at a maximum of 2A for PC board circuit to operate. 4. Protection Protection circuits inside the power supply shall cause only the power supply’s main outputs to shutdown. If the power supply latches off due to a protection circuit tripping, either a AC cycle OFF for 15 sec, or PSON# cycle HIGH for 1 sec must be able to restart the power supply. 6 4.1 Over Power Protection The OPP function shall work at 130%~270% of rating of output power, then all outputs shut down in a latch off mode. The latch shall be cleared by toggling the PSON# signal or by cycling the AC power. The power supply shall not be damaged from repeated power cycling in this condition. If only one module works inside the power supply, the OPP is at 110%~170% of rating of power supply. 4.2 Over Voltage Protection Each hot swap module has respective OVP circuit. Once any power supply module shut down in a latch off mode while the output voltage exceeds the over voltage limit shown in Table 7, the other modules should deliver the sufficient power to the device continually.

The power supply should be shut down in a latch off mode while the respective output current exceeds the limit as shown in Table 8. When the latch has been cleared by toggling the PSON# single or cycling the AC input power. The power supply module should not be damaged in this condition. Voltage Minimum Maximum Shutdown Mode +5V 110% 160% Latch Off +3.3V 110% 160% Latch Off +12V 110% 160% Latch Off Table 8 –Over Current protection 4.4 Short Circuit Protection The power supply shall shut down in a latch off mode when the output voltage is short circuit. 5.

Measurement will be made at 240 VAC and 60Hz. 7. Redundant Power Supply Function 7.1 Redundancy The redundant power supply is N+1=N (400W+400W=400W) function power supply, each one module is redundancy when any one module was failed. To be redundant each item must be in the Hot swap power supply module. 7.2 Hot Swap Requirements The redundant power supply modules shall be hot swappable. Hot swapping a power supply is the process of inserting and extracting a power supply from an operating. During this process the output voltage shall remain within the limits specified in Table 7 with the capacitive load specified Table 9. The Sub-system shall not exceed the maximum inrush current as specified in section 2.2. The power supply can be hot swapped by the following methods: AC connecting separately to each module. Up to two power supplies may be on a single AC power source. Extraction: The AC power will be disconnected from the power supply first and then the power supply is extracted from the sub-system. This could occur in standby mode or powered on mode. Insertion: The module is inserted into the cage and then AC power will be connected to the power supply module. 8 For power modules with AC docking at the same time as DC. Extraction: The module is extracted from the cage and both AC and DC disconnect at the same Time. This could occur in standby or power on mode. No damage or arcing shall occur to the DC or AC contacts which could cause damage. Insertion: The AC and DC connect at the same time as the module is inserted into the cage. No damage to the connector contacts shall occur. The module may power on or come up into standby mode. Many variations of the above are possible. Supplies need to be compatible with these different variations depending upon the sub-system construction. In general, a failed (off by internal latch or external control) supply may be removed, then replaced with a good power supply(must use the same model) , however, hot swap needs to work with operational as well as failed power supplies. The newly inserted power supply may get turned on by inserting the supply into the system or by system management recognizing an inserted supply and explicitly turning it on. 7.3 LED Indicators There shell be a single bi-color LED. The GREEN LED shall turn ON to indicate that all the power outputs are available. The Red LED shall turn ON to indicate that the power supply has failed, shutdown due to over current, or shutdown due to component failure.The LED(s) shall be visible on the power supply’s exterior face. The LED location shall meet ESD requirements. LED shall be securely mounted in such a way that incidental pressure on the LED shall not cause it to become displaced. 8. Reliability 8.1 Mean Time Between Failures (MTBF) The MTBF of the power supply shall be calculated utilizing the Part-Stress Analysis method of MIL217F or Bell core RPP. The calculated MTBF of the power supply shall be greater than 100,000 hours under the following conditions: Full rated load 120V AC input Ground Benign 25°C Technical information in this specification is subject to change without notice. The revision of specification will be marked on the cover. 9 9. Physical Characteristics Size 9.1 Power Supply Dimension: 150mm(W) x 85mm(H) x 199 mm(D) Mechanical drawing: 10
