S Series (AC-DC)

Like all of the Bel Power Solutions cassette series, the S line features high efficiency, high reliability, low output voltage noise and excellent dynamic response to load/line changes, with its very wide input voltage ranges of 8 ~ 385 VDC. They offer input over and undervoltage lockout, along with adjustable output voltage with remote on/off.

The Bel Power Solutions S Cassettes, with their 100W of output power, are well-suited for rugged applications seeking single or dual output converter configurations. These cassettes are available with or without PFC.

The Bel Fuse LR Series provides 240 to 300 watts across two isolated, adjustable outputs with a universal AC input (90–264 VAC) and DC input support (125–300 VDC). Featuring full power factor correction, up to 92% efficiency, parallel operation with active current sharing, and a 20 ms hold-up time, these converters are built for demanding industrial and railway environments. Safety-approved to IEC/EN 62368-1 and UL/CSA 62368-1, AREMA compliant, EN 45545 rated, and RoHS compliant — with a 5-year warranty.
