Large Image Download Center

Total Output Power:
450W peak and continue at 400W at 50°C environment temperature (Note 4)
1) +12V Peak current cannot over 10 seconds
2) Measured by a 20MHz bandwidth limited oscilloscope and the each output is connected with a 10uF Electrolytic Capacitor and a 0.1uF Ceramic Capacitor, output at rated load and nominal input, and environment at 25°C
3) Initial Setting Accuracy is at Input 110VDC and all output at 60% rated load
4) The total DC continuous power shall be kept with 400W and peak power at 450W for maximum 10 seconds at input voltage at 100-264VAC. With input voltage 90-99VAC the total DC continuous power shall be kept with 300W max. Maximum 150W for 3.3V and 5V combined output power and maximum 383W for 3.3V, 5V, and 12V
Input Specification:
Power On/Off:
The power supply will be turned on when the power On/Off pin is connected to secondary GND
Power Good Signal:
When power is turned on, the power good signal will go high 100ms to 500ms after all output DC voltages are within regulation limits
Power Fail Signal:
The power fail signal will go low at least 1mS before any of the output voltages fall below the regulation limits
Short Circuit Protection:
Fully protected against short circuit. Auto-recovery modes upon of short circuit condition, except 3.3V latch off mode
Over Voltage Protection:
+3.3V   3.76   4.2     4.9
+5V      5.74   6.3     7.5   VDC
+12V    13.4   15.0   15.6
at rated load and nominal input, Latch-off mode when over voltage occurred
Over Temperature Protection:
When the power supply operating over the temperature or over load limit, the power supply will be shut down automatically to protect itself
Fan Control:
A SELV fan control daughter board with a thermal switch to sense the temperature of the secondary heak sink. The fan acts with two steps: slow speed when the temperature is low and get into high speed when the heak sink temperature over the limit (find application note for details)
Environment Specification:
15.0 x 14.0 x 8.6 cm, Tolerance +/-0.4mm
