Samlex America SDC-23 20A Non-Isolated 24VDC to 12VDC Step-Down Converter

20A Non-Isolated Step-Down 24VDC-12VDC Converter

This high efficiency switch-mode step-down DC-DC converter converts an input voltage of 24 VDC nominal (range 20 VDC to 35 VDC) to a highly regulated output voltage of 12 VDC nominal (13.8 VDC) at 20 Amps. The SDC-23 DC-DC converter is non-isolated (no galvanic isolation between input and output) and meant for use in negative ground systems. Features include overvoltage/short-circuit protection, temperature compensated current limit, output-side overvoltage protection, input-side overvoltage/ transient protection and input-side reverse polarity protection. The SDC-23 DC-DC converter is designed for heavy duty applications.
