MEAN WELL LDH-45B-500W 500mA 21~86V DC Dimmable Constant Current LED Driver with 18~32V DC Input

The MEAN WELL LDH-45B-500W is a step-up (boost type) dimmable constant current LED driver LED driver with 500mA 21~86V output. It can take the power produced from 12V or 24V sources (such as solar panels, generators, or batteries) and provide a ‘clean’ constant current output suitable for powering LEDs. These LED drivers are fully encapsuled and feature a remote on/off control function. They can be dimmed by applying a 0.25~1.3V analogue signal, or a PWM signal. When a PWM signal is applied, the output current follows the duty cycle of the PWM waveform.
