Note
|
1. A parameters NOT specially mentioned are measured at 230VAC input, rated load and 25 ºC 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. Please connect positive pole of input voltage with mark “N” of terminal block, connect negative pole of input voltage with mark “L” of terminal block, using DC voltage for input voltage.
