constant current voltage led driver batery charging module lm2596 1.25~30v input Feature: 1.Use high quality chip LM2596, high precision(Max 92%), low calorific value. 2.Use the original low ESR Sanyo filter capacitor which can make the ripple voltage as low as 50mV. 3.Use machines to finish the SMD, reflow soldering. What’s more, all of those items have passed 2 hours burn-in test to make sure the stability before shipment. Application: 1.Charging for lithium battery: When the battery is under low voltage, it will be burned if we charge it with constant voltage. So we should charge it with constant current. 2.Driver high power LED: The power of one LED is limited, when we need higher brightness, we can use this module to achieve constant current drive for multiple LEDs. 3. Any other occasions which need constant current input. 2.Electric parameter. Output voltage: 7~35V. Input voltage: 1.25~30V. Output current: Max 3A. Transfer efficiency: 92%(Max). Switching frequency: 150KHz. Product size: 48mm(L)*23mm(W)*14mm(H). It is a adjustable step down power module, we can change the output voltage by adjusting the blue adjustable resistor. The input/output voltage difference value is 2V, the Min output voltage is 1.23V. Make sure the following pin connection are right, the wrong connect will bring damage to this module. “IN-” stands for input cathode. “IN+” stands for input anode. “OUT-”stands for output cathode. “OUT+”stands for output anode. How to charge the battery: 1). We should know the float voltage and charging current of the battery which needed to be charged, we also should know the input voltage of this module. 2). Adjust the Constant potentiometer until the output voltage is about 5V. 3). Use the 10A current function of the multimeter to test the input short-circuit current, adjust the constant-current potentiometer until the input current reaches the proper charging current. 4). Turn lamp current is default as 0.1 times of the charging current ( constant value ). 5). Adjust the constant-voltage potentimeter until the output voltage reaches the float voltage. 6). Connect it with the battery and test the charging. (For the 1,2,3,4,5 step, connect the input port of this module to the power supply and do not connect the output port with battery). 7).LED constant-current driver. (1). Make sure the operating current and maximum operating voltage of the LED driver. (2). Adjust the constant-voltage potentiometer until the output voltage is about 5V. (3). Use the 10A current function of the multimeter to test the input short-circuit current, adjust the constant-current potentiometer until the input current reaches the working current of the LED. (4). Adjust the constant-voltage potentimeter until the output voltage reaches the MAX working voltage of the LED. (5). Connect the LED, test it. ( For the 1,2,3,4 steps, just connect the input port of this module to the power supply, do not connect the output port with the LED.). 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 10A) 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). Aadjust constant voltage regulator, the output voltage about 5V. 3). With a multimeter ( to 10A) 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.). ezsuwhf sijpidk qyklede MPI Buyer should pay within 7 days after purchase. We only accept payment via PayPal.
