Connectors
Main connector: 24pin mini-FIT JR type. Two 3.5” drive power connector (one
ATA, one SATA). P4-12V wire harness.
Overload protection
Over load protection will be effected when either of the loads (+5V & +3.3V)
exceeds > 150% Max Load.
Turn-on Delay
After turning on, at least 20 ms will be needed for the rise of +5VSB output
voltage (measured from 10% to 95%) to reach its peak.
Remote ON/OFF control
Logic level is LOW - Output voltage is enabled (PS_ON pin)
Logic level is HIGH - Output voltage is disabled (PS_ON pin)
Operating environment
: Temperature: -20 to 55 degree centigrade.
NOTE: For fanless operation, please ensure that the PSU body temperature,
T(psu) does not exceed 65C. Higher temperatures are allowed, but MTBF could
decrease. Maximum power supply body temperature T(psu) is 85C.
Relative Humidity: 10 to 90 percent, non-condensing.
Efficiency, MTBF:
95%. MTBF=100K hours at T(PSU) 55Celsius.
