Adjustable Power Step-Down Module Supply Buck Converter Board Voltage Regulator Transformer DC-DC 8-60V to 3-32V Max 7A

Specifications: Input Voltage: DC 8V~60V (Recommended within 55V, Input voltage must be higher than the output voltage 1V above) Output Voltage: DC 3V~32V Continuously adjustable (It can save the last set voltage automatically) Output Current: Max 7A (Recommended use within 5A, Please pay attention to heat dissipation.) Accuracy: 1%, the voltage three bits display, the current two bits display, the unit is "A". Input Anti-reverse Protection: Yes Short Circuit Protection: Yes Conversion Efficiency: Max up to 95% Load Regulation S(I): ?0.8% Voltage Regulation S(U): ?0.8% Size: 62 x 44 x 18mm / 2.59 x 1.73 x 0.7in Weight: 67g Voltage Calibration Method: Power-off no load status, press and hold the left button access the power supply, release the left button, the display voltage starts flashing, then using multimeter measured the output terminal voltage, press the left and right keys to adjust the module display voltage value is the same as the multimeter display voltage value. Current Calibration Method: After calibrated the voltage is completed, connect the load, with a multimeter to measure the actual current value, power off the power supply, then press and hold the right button access the power supply, release the right button, the display current value starts to flash, press the left and right keys to adjust the module display current value is the same as the multimeter display current value. Package includes: 1 x Step-Down Module Kit 1 x Acrylic shell Note: If it is used for charging, after charging, please first disconnect the battery end and then the input end to prevent the battery from damaging the module by backflow. Or at the output end add a diode preventing backflow
