Samlex 12A Heavy Duty 24V to 12V Step-Down Converter

Description

The Samlex SDC-15 is a heavy-duty non-isolated DC-DC converter that steps a 24V nominal source down to regulated 13.8V DC for 12V equipment. It is designed for negative-ground marine, commercial-vehicle, heavy-equipment, and mobile applications that need dependable low-voltage power from a higher-voltage electrical system.

The converter accepts approximately 20-35V DC input and provides up to 12A at 13.8V DC. High-efficiency switch-mode circuitry helps keep the unit compact while supplying stable voltage for radios, lighting, audio systems, displays, and other 12V loads.

Protection features include cycle-by-cycle current limiting, short-circuit protection, output over-voltage protection, input over-voltage and transient protection, temperature-compensated current limiting, and reverse-polarity protection. These safeguards help protect both the converter and connected equipment during common electrical fault conditions.

The SDC-15 is non-isolated, so input and output share a common negative connection and the unit should be used in negative-ground systems. For 24V installations that need a rugged 12A step-down converter with regulated 13.8V output and comprehensive protection, the Samlex SDC-15 provides a reliable heavy-duty power solution. Worth comparing against our other DC-DC converters & power supplies.
