Notes

1. All paramterers NOT specially mentioned are measure at 230VAC input, rated load and 25°C of ambient temperature.

2. Ripple and noise are measured at 20MHz of bandwidth by using a 12” twisted pair-wire terminated with a 0.1uf and 47uf parallell capacitor.

3. Tolerance: includes set up tolderance, line regulation and load regulation.

4. 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.

5. Peak currecnt can not exceed 60 sec.

6. Isolated CH3 & CH4 maybe series connected of can be used as positive or negative outputs.

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

All specifications are typical at nominal input, full load, and 25°C unless otherwise noted
