Listed applications include consumer electronics, telecommunications, office equipment and industrial equipment. Select this complete model for the required output and connection.
Unless otherwise specified, parameters are measured at 115 VAC input, rated load, 25°C and 70% RH. DC output voltage is measured at the plug terminal at 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 to high input at rated load. Load regulation is measured from 10% to 100% of rated load. Check the static input and temperature curves together when selecting the operating load.
