rated load and +/- 10% of input voltage changing.

2.4Load 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.

2.5Step 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.

3.0General Features

3.1Efficiency

The efficiency is higher than 75% while measuring at nominal line and rated load.

3.2Hold 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.

3.3Protection

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.
