General Specifications:
Ripple and Noise: The peak to peak ripple and noise for +5V is less than 50mV. As for the other outputs are less than 100mV.  Measurement is done by 15MHz band width limited oscilloscope and terminated each output with a 0.47uF capacitor at rated loading, norminal line.


Line Regulation: The output line regulation for +5V is less than +/-1%, for +12V is less than +/-2%, for -12V and -5V is less than +/0-3% while measuring at rated loading and +/-10% of 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% rated load.
Output # +5V: +/-1%   +12V:+/-5%
Hold-up Time (ACE-890A): Hold-up Time is 16ms typical by measuring from the last AC line changing pulse to the point that +115V AC


Output Protection: The built-in over voltage protection circuit will shut down the outputs to prevent damaging external circuits.  The trip point of crowbar circuit is around 5.7V to 7.0V.


Efficiency: The efficiency is higher than 70% by measuring at norminal line and rated load.


Safety: Designed to meet the following standards
UL 1950 D3 (ACE-870A/870T/870C approved)
TUVS EN60 950 (ACE-870A/870T/870C approved)
CSA 22.2 No. 234


EMI: Meet the FCC docket 20780 curve "B" (ACE-890A)
