Bel Fuse HC12-3.4-A Power Supply

Bel Fuse HC12-3.4-A is a linear AC-DC power supply from Bel Power Solutions that delivers a fixed 12 V DC output at up to 3.4 A, for an output around 40.8 W. Designed as an open-frame module, it is intended for mounting inside equipment where a compact, fixed-output supply is required, and it belongs to Bel’s HC12 family. The unit accepts universal AC input in the AG family specification (87–264 VAC) and is RoHS compliant. Safety documentation for the HC12-3.4 family references IEC 62368-1:2018 conformity; the CB certification profile confirms these ratings for the product family. Availability is broad through major distributors and catalog listings, including Digi‑Key, Mouser, and RS‑Online, which show the HC12-3.4-AG/HC12-3.4-A model with 12 V output and 3.4 A capability. This combination of fixed 12 V output, 40+ watt capability, RoHS compliance, and open-frame packaging makes it a suitable supply for industrial controls and embedded electronic systems that require a compact mains-to-DC converter.
