1. Fixed turn lamp current is 0.1 times the current value ( Used to identify whether the battery is fully charged 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 driver2. Lithium battery(or lead accumulator) charge3. Vehicle-mounted power supply4. Low voltage system power supply5. 6V, 12V, 14V, 24V battery chargeMaterial: AluminumPackage Included:2 x DC buck converter module 12AOnly the above package content, other products are not included.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.
