The SDC-60 DC-DC converter is a highly effective switch-mode step-down DC-DC converter that turn an input voltage of 24 VDC nominal (range 20 VDC to 35 VDC) to a extremely regulated output voltage of 12 VDC nominal (13.8 VDC) at 60 Amps. This product is a non-removable (no active isolation between input and output) and is for use in negative ground systems. This converter contains overload, over-heating, reverse polarity and over-voltage protection.
