Input Voltage:
The range of input voltage is from 72~136VDC |
Input Current:
The maximum input current is 5A at 110VDC input |
Inrush Current:
Will not exceed 10A at 110VDC input cold start, 25°C |
Load Range:
At factory, all outputs in 60% rated load condition; the +5V output is set to between 4.80V and 5.20V. The other outputs are checked to be within the specified voltage accuracy range |
Ripple And Noise:
The peak to peak ripple and noise for +5V, +3.3V outputs are less than 50mV, and for the other output are less than 100mV at rated load. Measuring is done by 15MHz bandwidth limited oscilloscope and terminated each output with a 0.47uF capacitor electrolysis capacitor at rated load, nominal line |
Line Regulation:
The output line regulation for each output is less than +/-1% while measuring at rated load and -40~-72VDC input voltage changing |
Load Regulation:
The output voltage load regulation is less than the values in the following table by changing each output load +/-40% from 60% from rated load, and keep other outputs at 60% rated load |
Output Power:
The total DC continuous power shall be kept within 300W ambient temperature of 40°C below, and input voltage at 110VDC. The maximum, total combined output power on the 3.3V and 5V rails is 150W |
Power On Signal:
This TTL compatible signal (active low) is use to switch ON the main output. When power on is disconnected from secondary common, all outputs except +5Vsb shall turn off |
Power Good Signal:
When power start-up, the power good signal will increase between 100ms to 500ms after all output DC voltages are within regulation limits |
Power Fail Signal:
The power fail signal will fall at least 1ms before any of the output voltages lower than the regulation limits |
Efficiency:
The efficency is higher than 65% while measuring at nominal line and rated load |
Altitude:
Will operate properly at any altitude between 0 to 10,000ft |
Protection:
Over Voltage: For some reasons the power supply might fail to control itself, the build-in crowbar circuit will automatically shut down the outputs to avoid damaging the external circuits. The trip point of O.V.P. circuit is around 5.7V to 7.0V
Short Circuit: The power supply will go into hiccup mode function against short circuit or over load conditions. If the faults condition removed, the power supply will restart automatically |
Temperature:
0~+70°C, -20°C can start up, derating from 50°C (operating); -40~+75°C (storage) |
Humidity:
The power supply can operate from 5% humidity to 95% humidity non-condensing at 40°C |
