20A Non-Isolated Step-Down 24VDC-12VDC ConverterThis 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.Features: Advanced switchmode design; Mount in almost any location; Compact and light weight; Reverse polarity protection; High efficiency; Current limiting circuit; Overvoltage crowbar circuit; Non-Isolated for negative ground system; Specifications: Input: 20-30 VDC; Output: 13.8 VDC; Amps: 20 Amps; Weight: 2.2 (lbs); Weight: 1 (kg); Dimensions: 7.75 x 4.75 x 2.4 (in); Dimensions: 19.7 x 12.1 x 6.1 (cm); Warranty: 2 Year Limited; Applications: Earth moving equipment; Heavy trucks; Buses; Marine vehicles; CB radios; 12 Volt lighting systems; AM/FM sound systems; WARNING: This product can expose you to chemicals which are known to the State of California to cause cancer, birth defects or other reproductive harm.
