Input Voltage

The range of input voltage is from 72~136VDC

Input Current

The maximum input current is 5A at 110VDC input

Inrush Current

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

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

Specifications

Industrial Power Supply

Efficiency

The efficiency is higher than 65% while measuring at nominal line

and rated output

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 automaticallly 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

Humidity

The power supply can operate from 5% humidity to 95% humidity
