24 VDC-12 VDC Converter  SDC-12
 
This high efficiency switch-mode step-down DC-DC converter converts an input voltage of 24 VDC nominal (range 20 VDC to 32 VDC) to a highly regulated output voltage of 12 VDC nominal (13.6 VDC) at 12 Amps. The SDC-12 DC-DC converter is non-isolated (no galvanic isolation between input and output) and meant for use in negative ground systems. Features include short-circuit, reverse polarity and over-voltage protection.
