85~264VAC
47~63Hz at AC input
2A at 115VAC or 1.5A at 230VAC max.
The maximum inrush current will not exceed 30A at 115VAC or
60A at 230VAC input, cold start, 25°C
The adjustable range of +5V output is around 4.5~5.8V. At factory,
the +5V output is set to between 4.95~5.05V at 60% rated load,
and +/-12V are checked to be within the specified voltage accuracy
range. The peak load cannot exceed 5 sec.
The peak to peak ripple and noise for +5V output is less 50mV for
+/-12V output are less than 100 mV. Measuring is done by 15MHz
bandwidth limited oscilloscope and terminated each output with a
0.47μF capacitor
The line regulation for each output is less than +/-1% while
measuring at rated load and +/-10% of the input changing
The load regulation for +5V is less than +/-1%, for +/-12V is less
than +/-5%, measured is done by changing the measured output
load +/-40% from 60% rated load, and keep all other output at 60%
rated load
The hold up time is longer than 16mS at 115VAC input and rated
load, which is measured from the end of the last charging pulse to
when the main output drops down to 95%output voltage
The efficiency is higher than 75% typical while measuring at
nominal line and rated load
For some reasons the power supply fails to control itself, the
build-in over voltage protection circuit will shut down the outputs to
prevent damaging to external circuits. The trip point of crowbar
circuit is around 5.8V to 7V for output voltage. The power supply
will go into latch off mode against short circuit or over load
conditions
