SAFETY &

EMC

(Note4)

1. All parameters NOT specially mentioned are measured at 12,24,48VDC input, rated load and 25

of ambient temperature.

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

3. Tolerance : includes set up tolerance, 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.
