Feature: 1. WORKING VOLTAGE: The buck working mode ensures that the total voltage difference of the LED is 2‑3V lower than the input power supply voltage to work. 2. EXCELLENT CHIP: Adopt high efficiency, low consumption and stable chips to achieve the purpose of energy saving and environmental protection. 3. HIGH EFFICIENCY: Constant output current, low ripple, ensure the safety and stability of LED use, improve light efficiency and reduce light decay. 4. CIRCUIT PROTECTION: The DC constant current module has overload, short circuit and overcurrent protection to ensure the safety of the power supply. 5. PWM DIMMING: The module has multiple functions, supports PWM dimming, high level closes the output, low level opens the output, convenient and reliable. Specification: Item Type: LED Driver Module Input Range: DC5-35V Output: 700mA±20mA, drive 1-10 3W LEDs Function: Support PWM dimming, high level close output, low level open output, wide voltage input Wiring: VIN+ is the input positive pole, VIN- is the power input negative pole; LED+ is connected to the LED positive pole, LED- is connected to the LED negative pole. Package List: 6 x Module
