² Ripple and noise
The peak to peak ripple and noise for each output are
less than 1% of output voltage at rated load which is
measured by a 15MHz bandwidth limited
oscilloscope and each output is connected with
0.47
µ F capacitor.
² Line regulation
The line regulation is less than +/-1% at rated load
with +/-10% change in input voltage.
² Load regulation
The load regulation for +5V is less than +/-1%, for
+12V less than +/-10%, which are measured by
changing the output load from 20% to 100% of the
rated load and the other output is kept at 60% rated
load.

² Efficiency
The efficiency is higher than 70% while measuring at
normal line and rated load.
² Hold up time
The hold up time is longer than 16mS at 115V
AC
input and rated load
² Protection
a. Over voltage protection : The built-in crowbar
circuit will shut down the outputs to avoid
damaging the external circuits. This trip point of
over voltage protection is around 6.4V to 7.4V. To
recover from over voltage protection, cycle the AC
line OFF and ON to make it restart.
b. Short circuit protection : The power supply will
generate a hiccup mode to protect itself against
short circuit or over load conditions and will return
to normal after wrong conditions are removed.
