The fully waterproof PV Lighting Controllers series charge and lighting can be used with 12 or 24 VDC systems and are well-suited for operating area lighting or signage. MD-designated controllers have a motion sensor to activate the light or load when motion is sensed. Controllers with and without motion detectors are available in 15 A and 40 A versions. All controllers have low-voltage load disconnect (LVD) and temperature compensation and can be used with sealed or flooded batteries. Pulse action reduces sulfation.
