80W AC-DC ATX Power Supply

Large Image Download Center

Total Output Power:
80W at 50°C environment temperature (Note 4)
1) The maximum total combined output power on the +3.3V and +5V rails is 40W
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
3) The +5V output is set between 5.08V to 5.13V by variable resistor and all output at 60% rated load and the other outputs are checked to be within the accuracy range
4) Total maximum load cannot exceed 80W with 8.6CFM forced air-cooling and 60W convection cooling
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
Over Load Protection:
Fully protected against output overload and short circuit. Automatic recovery upon of overload condition
Over Voltage Protection:
For some reason the PSU fails to control itself, the build-in over voltage protection circuit will shut down the outputs and go into hiccup mode to prevent damaging external circuits. The trigger point is about 6.5V-8.5V at +5V and the PSU will auto-recovery once the failure condition been removed
Environment Specification:
12.8 x 8.1 x 4.0 cm, Tolerance +/-0.4mm
