3.3 Efficiency

The following table provides the required minimum efficiency level at various loading conditions.

These are provided at three different load levels: 100%, 50% and 20%.

Efficiency is tested over

an AC input voltage range of 115 VAC to 220 VAC.

3.4 AC Input Voltage Requirement

The power supply must operate within all specified limits over the input voltage range shown in

the following table.

Notes:

1. Maximum input current at low input voltage range is measured at 90 VAC, at maximum load.

2. Maximum input current at high input voltage range is measured at 180 VAC, at maximum load.

3. This is not to be used for determining agency input current markings.

4. Maximum rated input current is measured at 100 VAC and 200 VAC.

Harmonic distortion of up to 10% THD must not cause the power supply to go out of specified

limits.

The power supply powers off if the AC input is less than 75 VAC +/-5 VAC range.

The

power supply starts up if the AC input is greater than 85 VAC +/- 4 VAC.

Application of an input

voltage below 85 VAC does not cause damage to the power supply, including a fuse blow.

3.5 Protection Circuits

Protection circuits inside the power supply cause only the power supply’s main outputs to shut

down.

If the power supply latches off due to a protection circuit tripping, an AC cycle OFF for 15

seconds and a PSON

cycle HIGH for one second reset the power supply.
