Specifications
* Input Voltage:
85~270VAC
* Input Current:
2A at 115VAC or 1A at 230VAC max.
* Inrush Current:
Does not exceed 30A at 115VAC input or 60A at
230VAC input, at cold start 25
o
C, and excluding EMI suppression
capactiors
* Load Range:
All outputs are at min. load conditions, while +5V
output is between 5~5.1V and all other outputs are within the
specified voltage accuracy range
* Ripple and Noise:
Peak to peak ripple and noise for all outputs is <
1% of output voltage at rated load
* Line Regulation:
< +/-2% for each output measured at rated load
and +/-10% input voltage range
* Load Regulation:
< +/-3% for +5V, +/-4% for +12V, and +/-5% for -
12V with +/-40% change on the measured output load, +/-40% from
60% rated load, while keeping other outputs at 60% rated load
* Hold Up Time:
> 16ms at 115VAC input and rated load, measured
from the end of the last charging pulse to when the main output
drops down to 95% output voltage
* Efficiency:
> 70% at nominal line and rated load
