DC-DC 5-36V to 1.25-32V Step Down Buck Converter CC/CV Adjust Power Supply Module#091013 Product Description Module Parameters: Input voltage : 5-36V Output voltage :1.25-32V continuously adjustable,default output 17V. Output Current : 5A MAX( Please use it within 4.5A) Output Power: Max 75W ( Please use it within 50W. if the pressure difference is big,please reduce power) Operating temperature: -40 to +85 ° C Operating frequency: 180KHz Conversion efficiency : up to 96% Short circuit protection: Yes Overtemperature protection: (automatically shut off the output after overtemperature) Input reverse polarity protection: No, (if necessary, please in input String into high current diode) Installation: 4pcsx 3mm screws Wiring:(solder terminals) V-IN is the input, V-OUT is the output Usage: 1. Use as an ordinary buck module with overcurrent protection capabilities (1) Press the right button, LED adjust to the output voltage, adjust the "constant voltage potentiometer" so that the output voltage reaches the voltage value you need; (2) LED display is adjusted to Display output current, module output terminal directly short connect ( ie: use thick wire short circuit output terminal), at this time, adjust "constant current potentiometer" so that the current value of the digital Meter reaches the preset value of overcurrent protection; (Such as on-board ammeter shows current values 4A, then the module maximum current is limited 4A. current to 4A, the red light is on.) (3) connect to the load, it works. 2. Use as a battery charger (1) to determine the battery float voltage and charging current ( If lithium battery parameters is 3.7V / 2200mAh, then the float voltage to 4.2V, the maximum charging current is 1C, namely 2200mA) (2) no-load conditions, LED display is adjusted to Display output voltage,, adjust the "constant voltage potentiometer" so that the output voltage reaches the float voltage; (3) LED display is adjusted to Display output current, module output terminal directly short connect ( ie: use thick wire short circuit output terminal), at this time, adjust "constant current potentiometer" so that the current value of the digital table reaches the preset value of charge current value; (4) Charge turn the lamp current default factory is 0.1 times the charging current; (Battery charging current is gradually reduced, and gradually charged by a constant current constant voltage charging into, if the charge current setting is 1A, then when the charge current is less than 0.1A when the blue lights off, the green light is on, then the battery is fully charged.) (5) connect to the battery, then charge. (Step 1/2/3/4 : Input terminal connect power supply; Output terminal no-load, and don't connect the battery) 3. Use it as a constant current LED driver module (1) to determine the LED current and maximum operating voltage; (2) under the no-load conditions, LED display is adjusted to display output voltage,, adjust the "constant voltage potentiometer" so that output voltage reaches the LED operating voltage; (3) LED display is adjusted to Display output current, module output terminal directly short connect ( ie: use thick wire short circuit output terminal), at this time, adjust "constant current potentiometer" so that the current value of the digital table reaches the preset value of LED operating current; (4) connect LED, to test machine. (Step 1/2/3: input connect power supply; output no-load, don't connected LED lights.) Note: 1. If the module can not be adjusted, the output voltage is always equal to the input voltage." When you encounter this problem, please counterclockwise rotation of the potentiometer 10 laps or more, then you can adjust the output voltage. Because the factory default output voltage is 17V. 2. Module output terminal string has a current sampling resistor, there will be 0-0.2V voltage drop after connected to the load, it is a normal phenomenon. 3. If its output is more than 3A/35W, please enhance heat dissipation! Package include: 1xDC/DC Buck Converter Payment Method We accept only Paypal for both domestic and international.
