1. General This is the specification of Model IS-780PD8; it is intended to describe the functions and performance of the subject power supply. This PS/2 780 watts switching power supply with Active PFC (Power Factor Correction) capability, meets EN61000-3-2 and equips Full Range Input features. 2. AC Input Specifications 2.1 AC Input Voltage, Frequency and Current ( Rating: 100V-240Vac, 47-63Hz, 12-6A ) The power supply must operate within all specified limits over the input voltage range in Table 1.

Combined 180W 62A 760W Total Output Table 5 – Output Loads Note 1: Maximum continuous total DC output power should not exceed 780 W. Note 2: Single / Multiple rail(s) for +12V is adjustable by a switch. 3.
3.3 Timing Requirements These are the timing requirements for the power assembly operation. 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.
Table 11 – Turn On/Off Timing Item Description Tsb_on-delay MIN MAX Units Delay from AC being applied to +5VSB being within regulation. 1500 mS Tac_on-delay Delay from AC being applied to all output voltages being within regulation. 2500 mS Tvout_holdup All main output voltage stay within regulation after loss of AC 18 mS Tpwok_holdup Delay from loss of AC deassertion of PWOK. 17 mS Tpson_on_delay Delay from PSON# active to output voltage within regulation limits.
3.4 Remote On/Off Control : PSON# The PSON# signal is required to remotely turn on/off the power supply. PSON# is an active low signal that turns on the +5V, +3.3V, +12V 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 locted in power supply.
