>150% of rated output power or short circuit then constant current limiting. If output drops to 40% of
rated output voltage then shutdown and auto recover for 5 times attempts. If fault remains for more
than 5 attempts then latch off output and re-power on to recover.

Notes:

1. All parameters NOT specifically mentioned are measured at 230VAC input, rated load and 25°C ambient temperature

2. Ripple and noise are measured at 20MHz bandwidth by using a 12” twisted pair wire terminated with a 0.1µF ceramic & 47µF electrolytic capacitors across the output

3. Derating is required at low input voltages. Below 100VAC, derate linearly to 80% load at 90VAC

4. Tolerance: includes set up tolerance, line regulation and load regulation

5. The power supply is considered a component which will be installed into a final equipment. The final equipment must be re-confirmed that it still meets EMC Directives
