S Series (AC-DC)

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.

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.

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.
