Product Feature: DC to DC 8A high current buck power supply with constant current, constant voltage function. can be use as dc power supply, solar battery charger, Lithium Battery charger, with turn light indicator. can be use as high power LED driver module. Feature: Module Properties: non-isolated step-down module (BUCK) Input Voltage: DC 7-40V Output voltage: DC 1.25-36V continuously adjustable Output current range: 0.05-8A (the default output current is 1A) Turn light current: constant current value * (0.1), such as the constant current value is 3A, Turn light current is set to constant current of 0.1 times (0.1 * 3A = 0.3A), when adjusted constant current value to 2A, then Turn light current is constant current of 0.1 times (0.1 * 2A = 0.2A). this version is 0.1 times fixed Operating temperature: -40°C to +85°C Operating Frequency: 180KHz Conversion efficiency: Up to 95% (efficiency depnd on the input and output voltage, current, pressure) Short circuit protection: Yes (Limit the current to the set current value) Over-temperature protection: Yes (over-temperature shutdown output automatically) Input reverse polarity protection: Yes (please do not reverse connection for long time) Output protection against anti-irrigation: none Charging (turn lights) indication: Yes (charging red, full charger blue, constant current green) Wiring: IN+ IN- as the input positive and negative, OUT+ OUT- as the positive and negative output Aluminum Case Size: 70MM x 39MM x 31MM Battery Charging method: 1.Make sure the recharge battery float voltage and charge current, input voltage of the module. 2.adjust constant voltage regulator, the output voltage about 5V. 3.With a multimeter ( to 20A) Measuring output Short-circuit current, Also adjust the constant regulator allows Output current reaches a predetermined charge current value; 4.Adjust Constant regulator allows Output voltage reaches the float voltage; 5.connected to the battery, try charging. (1,2,3,4 step input connect power, output do not connect battery.) LED constant current driver Usage: 1.Make sure LED current and the maximum operating voltage; 2.adjust constant voltage regulator, the output voltage about 3V. 3.With a multimeter ( to 20A) Measuring output Short-circuit current, Also adjust the constant regulator allows Output current reaches a predetermined LED working current value; 4.Adjust Constant regulator allows Output voltage Reach LED maximum working voltage; 5.Connected to the LED, test. (1,2,3,4 take steps input connect power, output do not connected LED.) Package Include: 1x DC Converter ------------------------------------------A077------------------------------------
