24VDC to 12VDC 1.5A to 100A Step Down Non-isolated DC-DC Buck Power Converter

24V to 12V Series

This highly efficient switch mode step-dwon DC-DC converter converts an input voltage of 24 VDC nominal (range 18 VDC to 36 VDC) to a highly regulated output voltage of 12 VDC nominal. These DC-DC converters is non-isolated (no galvanic isolation between input and output) and meant for use in negative ground systems. Features include waterproof, overcurrent,short-circuit and overvoltage protection.
