The range of input voltage is from 72~136VDC
The maximum input current is 5A at 110VDC input
Will not exceed 10A at 110VDC input cold start, 25°C
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
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 0.47 μF capacitor electrolysis
capacitor at rated load, nominal line
The output line regulation for each output is less than +/-1% while
measuring at rated load and -40~-72VDC input voltage changing
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
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
This TTL compatible signal (active low) is use to switch ON the When power start-up, the power good signal will increase between
100ms to 500ms after all output DC voltages are within
regulation limits
The power fail signal will fall at least 1ms before any of the
output voltages lower than the regulation limits
The efficiency is higher than 65% while measuring at nominal
line and rated output
Will operate properly at any altitude between 0 to 10000ft
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
0~+70°C, -20°C can start up, derating from 50°C (operating);
-40~+75°C (storage)
The power supply can operate from 5% humidity to 95% humidity
non-condensing at 40°C
