Taidacent 100mA to 1A Adjustable 1-10 String LED Constant Current PT4115 Driver Module Power Drive Board Led Panel Light Driver
Product Description
This is a step-down constant current board, input 5-32v, the input voltage must be 1v higher than the voltage required by the LED lamp, otherwise the current will not reach the set value, this is a constant current board, not a step-down regulator board, Many people always ask how many volts to output. The board only controls the current, and the voltage will automatically adjust to the voltage required by the LED. For example, if the load is connected to a 3V LED bead, the input voltage is 5-32V, and the voltage at both ends of the LED light is always the same. About 3V, the two strings are about 6V, do not measure the output voltage with no load, the no-load output voltage is equal to the input voltage, it is a virtual voltage, this is a step-down constant current, not a boost constant current, for example, two strings of LED lights can only be turned on at 6V On, the input 5V is not on, the input voltage must be above 7, as mentioned above, the input voltage must be greater than the voltage required by the LED lamp by 1V or more, the output current calculation formula: l=0.1/RCs, the current sampling resistor RS1 on the board and RS2 is connected in parallel, you can know how much current the board is by looking at the resistance value, R200=500mA, R330=300mA, 1R=100mA, there is only one sampling resistor on the board, 1R=100mA, two 1R resistors are 100mA+100mA=200mA, 1 One R330=300mA, two R330=600mA, R200=500mA, R200+R200=1A, R200+R330=800mA.
