rated load and +/- 10% of input voltage changing.
2.4 Load regulation
The load regulation for +24V is less then +/-1%, for +5V is less then +/-5%,
measuring is done by changing the measured output load +/-40% from 60%
rated load, and keep other output at 60% rated load.
2.5 Step regulation
When +24V load changes from min. to peak load or from load to min. load ,
the 5V should keep within 5V +/-5% at rated load.
3.0 General Features
3.1 Efficiency
The efficiency is higher than 75% while measuring at nominal line and rated
load.
3.2 Hold up time
The old up time is longer than 16ms at 115VAC input and rated load, which
is measured from the end of the last charging pulse to when the main output
drops down to 95% output voltage.
3.3 Protection
For some reason the power supply fails to control itself, the build-in over
voltage protection circuit will shut down the outputs to prevent damaging
external circuits. The trip point is around 26V to 31V. The power supply will
go into latch-off mode against short circuit or over load conditions, and have
to OFF and ON the AC input to restart the power supply.
