Applicable to LED driver, vehicle power supply, battery charging, regulated power supply, etc. Specification: Input current: Maximum 10A Continuous input current: Maximum 8A Output current: Maximum 8A Continuous output current: Maximum 6A Constant current adjustable: 0.5-8A Output power: Maximum 180W Standby current: About 20mA Conversion efficiency: About 90% Reverse polarity protection: No, please first determine positive and negative and then power on Dimensions: Approx. 70 x 52 x 21mm / 2.76 x 2.05 x 0.83in Weight: 74g (approx.) 2. Adjust the current adjustment potentiometer clockwise by about 20 turns to set the output current to the minimum, connect the LED, and adjust to the current you need. For battery charging, after the battery is fully discharged, connected the battery to the output and adjust to the current you need. Please do not adjust the current by short circuit due to the circuit structure of this boost buck module. Package List: 1 x Boost Buck Converter Note: 1. The input and output current cannot work at the Maximum value, and the input plus output currents can not exceed 12A 2. When the module temperature exceeds 65 ℃, heat dissipation needs to be strengthened. Package List
