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.
