a¦aЂ“a°a?a»a?a§a 1/2 aЂ~a©a?aµ 6 DC 8A 80W Adjustable Step Down Buck Converter CVCC 7-40V To 1.25-36V LED Driver Description: 100% brand new and high quality Quantity:1pc Weight:79 g Color: as picture show Aluminum case size:70mmx38mmx30mm/2.76"x1.50"x1.18"(inch) (approx) DC-DC8A - high current step-down voltage constant current module. Which can be used for all DC power, solar battery charging. With light prompt. Convenient to observe the state of charge. Can be used for high power LED driver module. Features: *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 constant current is 3A). *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. Battery charging useage methods: 1. Determine the float voltage that you need to charge the battery and charging current, module input voltage; 2. Adjustable constant voltage (CV) potentiometer. The output voltage is regulated to about 5V; 3. Multimeter 20A current block measurement output short circuit current. Meanwhile regulating constant current potentiometer (CC) to make the output current reaches a predetermined value of the charging current; 4. Turn the lamp current and the value of constant current charge linkage lamp current default is 0.1 times of charging current (current value); 5. Adjustable constant potentiometer to make the output voltage to the floating charge voltage; 6. Connect the battery, try charge (1, 2, 3, 4, 5 steps as the module input power supply, output no-load not connected to the battery) . LED constant current driving, useage methods: 1. Determine the current that you need to drive LED and maximum working voltage; 2. Adjustable constant potentiometer (CV). The output voltage is regulated to about 3V; 3. Multimeter 20A current block measurement output short circuit current, meanwhile regulating constant current potentiometer (CC) to make the output current is up to predetermined LED working current; 4. Adjustable constant potentiometer to make output voltage to the LED maximum working voltage; 5. Connected to the LED, try machine (1, 2, 3, 4 steps as the module input power, output no-load not connected to the LED lamps). Note: Constant current setting. The input voltage is higher than 7V, and the output setting voltage is higher than 2.5V. Otherwise, the function of constant current will fail. Reminder: Please don't connect input and output altogether. So it will cause the current sampling resistor bypassed. Sure, it can not to control output current. Small load, current is not adjustable. Big load will burned the main chip. So please make sure to pick input negative and output negative separately.
