Safety Standards
*Safety: UL 1950 / CSA 22.2 No.234 / VDE EN60950
*Inrush Current: Does not exceed 40A at 115VAC input or
80A at 230VAC input, at cold start 25oC
*EMI: FCC class B / EN55022B
*EMS: Level 3 of IEC-801, 802, 803, 804
*Ripple And Noise: Peak to peak ripple and noise for each
output is < 1% of each output voltage at rated load
115~230VAC
*Line Regulation: < +/-1% at rated load with +/-10% change
in input voltage
PIN
Output
*Load Regulation: The output voltage load regulation is less
than the values on the table when each output loading changes
+/-40% from 60% rated load while all other outputs at 60%
rated load
*Hold Up Time: > 20ms 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
*Power Good Signal: Goes high 100~500ms after all DC
output are ready

*Power Failure: Goes low 0.5ms before any DC output falls
*Power On: TTL compatible signal (active low) used to switch
ON the main output. When power on is disconnected from
secondary common, all outputs except +5Vsb are turned off
*Efficiency: > 65% at nominal line and rated load
*Altitude: 10,000 feet
