1. Fixed turn lamp current is 0.1 times the current value ( Used to identify whether the battery is fully When charging). 2. 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 drift less than 1%). Particularly suitable for LED driver. 3. High output current, the max output current can reach 12A. 4. Four high frequency capacitance, can lower output ripple, enhance the work stabilization. 1. High-power LED driver 2. Lithium battery(or lead accumulator) charge 3. Vehicle-mounted power supply 4. Low voltage system power supply 5. 6V, 12V, 14V, 24V battery charge Material: Aluminum Package included 1 x DC buck converter module 12A Note:Light 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.
