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 cells 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 Code 110786 110788 Description SCM-N 20 SCM-N 40 Specifications Battery Charger System voltage (battery) 12/24 V auto select 12/24 V auto select Nominal charge current 20 A 40 A Battery types AGM, Gel, flooded AGM, Gel, flooded Battery temperature sensor optional, product code 110610 optional, product code 110610 Switchable output (max. current) 20 A 40 A Energy consumption (night) < 7 mA < 7 mA Specifications solar input (DC) Panel type (12 V system) 36 cells 36 cells Panel type (24 V system) 72 cells 72 cells Max.
