PACKING
1. All parameters NOT specially mentioned are measured at 230VAC 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. 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.
