MGDBK25HF

MGDK25 25W POWER BOARD MOUNTED ISOLATED DC/DC CONVERTER 1500 Vdc ISOLATION Description The MGDK25 series features a Quality Cost Effective range of 25W board mounted isolated dc/dc converters. With multiple selection of wide input voltage ranges, the MGDK25 is proposed with a single, double, symmetrical or triple output channel. The converter embeds an output overload protection, and comes encapsulated in a low profile fully potted 2’’x2’’X0.5’’ metallic case.

When the output current reaches a value above typically 200% of it’s full-rated current, the converter falls into hiccup mode by testing periodically if an overload is applied. The module restarts automatically to normal operation when overcurrent is removed.
