Normally works within 110 ~ 125% rated output power for more than 3 seconds and switches to constant current limiting, with

auto-recovery after the peak load condition is removed

Protection type : Constant current limiting, recovers automatically after fault condition is removed

Constant current limiting, if >125% rated power, with auto-recovery after the overload condition is removed

Protection type : Shut down o/p voltage, re-power on to recover

Shut down O/P voltage, recovers automatically after temperature goes down

1. All parameters NOT specially mentioned are measured at 230VAC input, rated load and 25

of ambient temperature.

℃

2. Peak current or peak power up to 3 seconds is provided.

3. Ripple & noise are measured at 20MHz of bandwidth by using a 12" twisted pair-wire terminated with a 0.1uf & 47uf parallel capacitor.

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

5. Line regulation is measured from low line to high line at rated load.

6. Load regulation is measured from 0% to 100% rated load.

7. Length of set up time is measured at cold first start. Turning ON/OFF the power supply very quickly may lead to increase of the set up time.

8. Derating may be needed under low input voltages. Please check the derating curve for more details.

9. The power supply is considered as an independent unit, but the final equipment still need to re-confirm that the whole system complies with the

EMC directives. For guidance on how to perform these EMC tests, please refer to “EMI testing of component power supplies.”
