The 50-W ZWS50BAF and 75-W ZWS75BAF combine 76% to 78% typical efficiency, operating temperature from –10° to +50°C without derating, and up to 10-years electrolytic capacitor life. They accept ac input from 85 to 264 Vac, measure 2.0 x 5.2 x 1.0-in (ZSW50BAF). and 2.0 x 5.9 x 1.3-in. (ZWS75BAF). The supplies suit applications in light industrial, factory automation, LED signage, test and measurement, gaming, point-of-sale and IT equipment.
The open-frame power supplies feature ac-input with PFC and can operate from a 120 to 370-Vdc input. The supplies also are designed to withstand 3-kVac, input-to-output. They provide output voltages of 3.3, 5, 12, 15, 24 or 48 Vdc and have a ±10% adjustment range for nonstandard system requirements. (From $41 ea/500 — available now.)
