Details
Meanwell LDH-25-250 is 25W DC-DC Step-Up LED drive with 250mA12.5-84VDC21W5%9.5~32VDC91.5%/12V '94%/24V2.5A/12VDC1.2A/24VDC. The item features constant current output. Meanwhile, it could operate from 9.5~ 32VDC and offer model with rated current 250mA. Since the efficiency reaches high up to 95.5% with 94V-0 flame retardant plastic case, and fully-potted silicone enhancing the heat dissipation. these allow the unit to meet solar LED street light. In addition, it is equipped with various function options such as dimming methodologies. Due to its long lifetime, high efficiency and excellent quality, Meanwell LDH-25-250 is an ideally suitable solution for the optimal design flexibility for DC source LED lighting system.
