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 designMount in almost any locationCompact and light weightReverse polarity protectionHigh efficiencyCurrent limiting circuitOvervoltage crowbar circuitNon-Isolated for negative ground systemSpecifications:Input: 20-30 VDCOutput: 13.8 VDCAmps: 20 AmpsWeight: 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 LimitedApplications:Earth moving equipmentHeavy trucksBusesMarine vehiclesCB radios12 Volt lighting systemsAM/FM sound systemsWARNING: This product can expose you to chemicals which are known to the State of California to cause cancer, birth defects or other reproductive harm.
