Unless otherwise stated, specifications use 230 VAC input, rated load, 25°C and 70% RH. Output voltage is set at the plug terminal with 50% load.
Ripple and noise are measured with 20 MHz bandwidth, a 12-inch twisted pair and parallel 0.1 µF and 47 µF capacitors. Voltage tolerance includes set-up tolerance, line regulation and load regulation.
Line regulation is measured from low line to high line at rated load. The measurement note specifies load regulation over 20% to 100% rated load and cross regulation within ±15%; observe the individual channel limits and minimum-load ranges above.
