This solar charge regulator, based on PWM technology, is a great solution to charge your batteries with solar energy. Suitable for both 36 cells panels (in 12 V systems) and 72-cell panels (in 24 V systems). Its protection against water spray, suitability for high ambient temperature and compatibility with negative grounding make it the perfect solar regulator for marine and mobile environments. Optionally, a temperature sensor is available.Safe, user-friendly and flexibleThe SCM40 PWM is suitable for all types of lead-acid batteries in both 12 V and 24 V. The device features a large display and switchable output with evening/night lighting function.Specifications Battery ChargerSystem voltage (battery): 12/24 V auto selectNominal charge current: 40 ABattery types: AGM, Gel, floodedBattery temperature sensor: Optional, Product code 41500500Switchable output (maximum current): 40 AEnergy consumption (night):Specifications Solar Input (DC)Panel type (12 V system): 36 cellsPanel type (24 V system): 72 cellsMax.
