MHFS3 / MHFW3 3W Isolated DC-DC Converters

Cosel MHFS3 / MHFW3 3W Isolated DC-DC Converters are single- and dual-output devices in a standard SIP8 footprint that provides 2xMOOP for medical electrical equipment. The series features 3KV_AC I/O isolation voltage, built-in remote on/off, and adjustable external output voltage. Cosel MHF DC-DC converters include multiple safety-agency approvals and come with a five-year warranty.
