MTBF na
  • The maximum combined total output power on the 3.3V and 5V rails is 90W.
  • Initial Setting Accuracy is at Input 110VAC and all output at 60% rated load.
  • The total DC continuous power shall be kept with 150W at input voltage at 110-264VAC. With input voltage
    90~109VAC the total DC continuous power shall be kept with 120W max. The maximum total combined
    output power on the +3.3V and +5V rails is 90W. On condition of with option cover, the maximum 150W
    is at 30°C environment temperature.
Interface Signals and Internal Protection
Power On/Off The power supply will be turned on when the power On/Off ping is connected to secondary GND.
Power Good Signal When power is turned on, the power good signal will go high 100 ms to 500 ms after all output DC voltages are within regulation limits.
Power Fail Signal The power fail signal will go low at least 1 ms before any of the output voltages fall below the regulation limits.
Short Circuit Protection Fully protected against short circuit. Latch off mode upon of short circuit condition.
Over Voltage Protection The over voltage protection circuit will shut down the outputs to prevent damaging external circuits if error conditions occurred. The trigger point is about 5.4~6.4V at +5V. If the OVP occur, PSU cannot be recovered.
Over Temperature Protection Fully protected against output overload or over temperature. The protection point is at the temperature of the HS1 over 110 °C. After the temperature of HS1 goes down, the power supply will restart automatically.
