EB3600-AB | Chapter 4 General & Technical Information 88
The power supply module is capable of replacing / exchanging with active current sharing and/or isolation
MOSFETs built in for +12V output, and droop current sharing and/or isolation diode built in for +5Vsb output.
The AC input is rated 90-264Vrms with power factor corrected (PFC > 0.95). A 38mm high reliable Sanyo
Denki fan is installed to the power supply module for cooling the power supply module, power devices on
the distribution backplane and part of the system.
AC Input
Table 1 lists AC input voltage and frequency range for continuous operation. The power supply is capable
of supplying full-rated output power over the input voltage ranges specified.
a) The inrush current of power supply module is less than 120A under the conditions of 240Vrms input and
25oC ambient cold start. The inrush current is limited to the extent that no damage will be done to the
power supply
under any specified line, load, and temperature conditions.
b) The leakage current of the power supply module is less than 1.5 mA measured at 264Vac input.
c) The repetitive ON/OFF cycling of AC input voltage will not damage the power supply.
d) The power supply can automatically recover from AC power loss.
e) The power supply is equipped with primary fuse for input over-current protection, and meets product
safety requirement.
DC Output
DC Output Voltage Regulations
The DC output voltages remain within the regulation ranges shown in Table 2 for both the power supply
module and the completed power system when measured at the load end of the output connectors
under all AC line, O/P loads, and environmental conditions.
a) The remote sensing is provided to +12V, +5V, and +3.3V outputs to compensate for excessive cable
drops.
b) +5V, +3.3V, and -12V outputs are located on the power distribution backplane.
DC Output Load Distributions
The Table 3 defines the power supply typical output load distribution.
