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: +/-3%   +12V:+/-3%
              -5V: +/-5%     -12V +/-5%

 

Hold-up Time: Hold-up Time is 16ms typical by measuring from the last AC line changing pulse to the point that +5V drop down to +4.75V

 

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. The power supply will go into hiccup mode against short circuit or over load conditions, and will autorecovery while faulty conditions are removed.

 

Efficiency: The efficiency is higher than 73% 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-870A)
