MeanWell LED Driver

LDH-45B-1050WDA is a DC/DC step-up converter with constant current output and a wide input voltage range. It features built-in EMI filters (according to EN55015), PWM, analog dimming, and remote ON/OFF capabilities. The device includes protection against short circuits and overtemperature, making it suitable for driving LED lighting with cooling by free convection. The LDH-_WDA version comes with stranded wires and DALI dimming.

Note: Important information! Please do not dimension your LED driver/LED transformer too small. Choose a LED driver/LED transformer that has about 1/3 more power (Watt). The decisive factor for the load of the LED driver is not the wattage specification of the LED manufacturer but the actual current consumption (ampere) of the LED. It must be taken into account that the inrush current is much higher.
