NOTES

1. Input voltage is 90 ~ 260VAC however, the unit does not reach full power until >170VAC. See derating curve below.

2. All parameters NOT specially mentioned are measured at 230VAC input, rated load and 25 of ambient temperature.

3. Ripple & noise is 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. Current limiting 3 times (1.5s, 3.0s, 5.0s) then intelligent auto recovery before shut down

6. The power supply is considered a component, which will be installed into final equipment. The final equipment must be re-confirmed

that it still meets EMC directives.
