Specification:100% brand new with high qualityInput Voltage: DC 7-32VOutput voltage: DC 0.8-28V continuously adjustableOutput Current: 12AConstant current range: 0.2-12A (adjustable)Output Power: Maximum power is about 300WConversion efficiency: up to about 95%High-power LED driverLithium battery (or lead accumulator) chargeVehicle-mounted power supplyLow voltage system power supply6V, 12V, 14V, 24V battery chargeFixed turn lamp current is 0.1 times the current value (Used to identify whether the battery is fully charged when charging).Made from a dedicated benchmark IC and high-precision current sensing resistor, proving a more stable constant current, (when 20 to 100 constant current 1A, temperature drifts less than 1%). Particularly suitable for LED driver.High output current, the max output current can reach 12A.Four high frequency capacitance can lower output ripple, enhance the work stabilization.Package Included:1 x DC Buck Converter ModuleNote:Light shooting and different displays may cause the color of the item in the picture a little different from the real thing.The measurement allowed error is +/- 1-3cm.
