Features: _x000D_ Made with high quality electronic component for high stability and performance. _x000D_ High output current, the maximum output current can reach 8A. _x000D_ Using high thermal conductivity aluminum heat sinks for quick heat dissipation. _x000D_ Output voltage and output current are adjustable. _x000D_ Applicable to LED driver, vehicle power supply, battery charging, regulated power supply, etc. _x000D_ _x000D_ _x000D_ Specification: _x000D_ Module properties: Non-isolated voltage regulator _x000D_ Input voltage: 10.5-70VDC _x000D_ Input current: Maximum 10A _x000D_ Continuous input current: Maximum 8A _x000D_ Output voltage: 5-58VDC _x000D_ Output current: Maximum 8A _x000D_ Continuous output current: Maximum 6A _x000D_ Constant current adjustable: 0.5-8A _x000D_ Output power: Maximum 180W_x000D_ (The maximum current is 8A when working at low voltage, the maximum output of bare board without auxiliary heat dissipation is 30W, and the maximum output is 50W with heat sink without fan.)_x000D_ Standby current: About 20mA _x000D_ Conversion efficiency: About 90% _x000D_ Reverse polarity protection: No, please first determine positive and negative and then power on _x000D_ Dimensions: Approx. 70 x 52 x 21mm / 2.76 x 2.05 x 0.83in _x000D_ Weight: 74g (approx.) _x000D_ _x000D_ Output Voltage / Current Regulation Method: _x000D_ 1. Adjust the voltage adjustment potentiometer (clockwise to reduce the voltage, counterclockwise to increase the voltage), set the output voltage to the voltage you need according to your load requirements. _x000D_ 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. _x000D_ _x000D_ Package List: _x000D_ 1 x Boost Buck Converter _x000D_ _x000D_ Note: _x000D_ 1. The input and output current cannot work at the Maximum value, and the input plus output currents can not exceed 12A _x000D_ 2. When the module temperature exceeds 65 , heat dissipation needs to be strengthened.
