Information about MEAN WELL ELGC-300-H-AB

Equipped to drive low-voltage, high-current LED configurations, the MEAN WELL ELGC-300-H-AB features both internal potentiometer fine-tuning and versatile external 3-in-1 dimming (0–10V DC, 10V PWM, resistance). Supplying 301 W across an operating output window of 29–58 V DC, it caters directly to demanding high-density COB array lighting layouts. Encapsulated inside a ruggedized, IP67-rated metal housing, the driver maintains total immunity against dust ingress and continuous moisture exposure. Outstanding mechanical resilience ensures steady operation when subjected to high-impact environments with up to 5G vibration resistance. Circuit protection is further reinforced by a strong input-to-output isolation voltage of 3750 V AC. Certified under the strict UL8750 Type HL safety rating for hazardous locations, this high-amperage power supply is an excellent choice for stadium floodlights, commercial horticulture fixtures, and heavy industrial installations.
