Samlex 30A Non-Isolated 24V to 12V Step-Down Converter

This Samlex SDC-30 (30A Non-Isolated Step-Down Converter) converts an input voltage of 24 VDC nominal (range 20-32 VDC) to a highly regulated output voltage of 12 VDC nominal (13.8 VDC) at 30 amps. It is designed for boaters who want a high efficiency switch-mode design meant for use in negative ground systems.

This converter has no galvanic isolation between input and output, mounting in almost any location thanks to its compact, lightweight design. Features include overload, over-heating, reverse polarity, and over-voltage protection, with a cycle-by-cycle current limiting circuit and short circuit protection.
