1. General This is the specification of Model IS-550R8P; it is intended to describe the functions and performance of the subject power supply. This 550 watts Redundant 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, 10-5A ) The power supply must operate within all specified limits over the input voltage range in Table 1.
3. DC Output Specification 3.1 Output Current / Loading The following table defines power and current rating. The power supply shall meet both static and dynamic voltage regulation requirements for minimum load condition. Output Voltage +5V +3.3V +12V -5V -12V +5VSB Max. Load 30A 24A 41A 0.5A 1A 2A Min. Load 2A 1A 2A 0A 0A 0.1A 2.5W 12W 10W Max. Combined Total Output 180W 525W Table 2– Output Loads Range 1: Note 1: Maximum continuous total DC output power should not exceed 550 W.
PSON# controlling the On/Off of the power supply. Item Description Tsb_on-delay Delay from AC being applied to +5VSB being within regulation. Tac_on-delay Tvout_holdup MIN Delay from AC being applied to all output voltages being within regulation. All main output voltage stay within regulation after loss of AC Tpwok_holdup Delay from loss of AC deassertion of PWOK. Tpson_on_delay Delay from PSON# active to output voltage within regulation limits.

PSON# is an active low signal that turns on the +5V, +3.3V, +12V,-5V and –12V power rails.
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.
6. Agency Requirements 6.1 Safety Certification.
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.
