XINY DC 24V To 12V CC CV Step Down Volts Regulator Constant Current/Voltage 8A DC Adjustable Buck Converter 7-40V To 1.2-35V LED Driver Charger Module With Charging Indicator Solar Power Supply DIY Item Description Module Properties: non-isolated step-down constant current , constant voltage module (CC CV) charging module. Input voltage : DC 7-40V . Output voltage :DC 1.2-35V continuously adjustable . Output Current: 8A ( when power tube's temperature exceeds 65 degrees, please add cooling fan ) . Constant current range :0.2-8A ( adjustable ) . Turn lamp current : constant current value * ( 0.1 ) , turn the lamp current and constant value linkage, such as constant current value is 3A, turn the lamp current is set to a constant current is 0.1 times (0.1 * 3A = 0.3A). Lowest pressure : 1V . Output Power: 300W, Maximum . Conversion efficiency : up to about 95% . Operating frequency : 300KHZ . Output ripple : 20M bandwidth . Input 24V Output 12V 5A ripple around 50mV ( excluding noise ) . Operating temperature : Industrial grade (-40 °c to +85 °c) ( please note the actual use of the power tube temperature , high temperature heat strengthened please ) . No-load current : Typical 20mA (24V switch 12V) . Load regulation : ± 1% ( constant ) . Voltage regulation : ± 1% . Dynamic response speed : 5% 200uS . Potentiometer adjustment direction : clockwise ( increase ) , counterclockwise ( decrease ) . the potentiometer(CV) closed to the input voltage is used to regulate voltage, the potentiometer(CC) closed to output voltage is used to regulate current (CC) . Indicator : dual color indicator , charging indicator light is red , the green light means fully charged ( No load is green ) . Output short circuit protection : Yes , constant current. Size:65*47*23.5 mm. Weight:66g. Battery recharging methods: 1. Determine whether you need to recharge the battery float voltage and charge current, input voltage of the module. 2. Adjust the constant voltage potentiometer, the output voltage is regulated to about 5V. 3. 10A current with a multimeter to measure the output short-circuit current block, while adjusting the constant current potentiometer allows the output current reaches a predetermined charge current value. 4. Adjust the constant voltage potentiometer to make the output voltage reaches the float voltage. 5. Connect the battery, try charging. (1,2,3,4 take steps to block input power, output load is not connected to the battery.). LED constant current drive to use: 1. Determine whether you need to drive the LED current and the maximum operating voltage. 2. Adjust the constant voltage potentiometer, the output voltage is regulated to about 5V. 3. 10A current with a multimeter to measure the output short-circuit current block, while adjusting the constant current potentiometer allows the output current reaches a predetermined LED operating current. 4. Adjust the constant voltage potentiometer to make the output voltage reaches the LED maximum working voltage. 5. Connect LED, the test machine. (1,2,3,4 step input module connected to the power supply, output load is not connected LED lights. ). Shipping Our stock all ships from our US-based warehouses.
