SCM20 PWM

Product catalog summary

Overview
The SCM20 PWM is a solar charge regulator designed for charging batteries using solar energy. It is compatible with both 12 V and 24 V systems, making it suitable for 36 cells panels in 12 V systems and 72 cells panels in 24 V systems. Its robust design includes protection against water spray, high ambient temperatures, and compatibility with negative grounding, making it ideal for marine and mobile environments. An optional temperature sensor is available for enhanced functionality.

Key Features

Compatible with all types of lead-acid batteries (AGM, Gel, flooded).
Features a large, backlit LCD display with switchable output and evening/night lighting function.
Passive cooling system and common negative grounding.
Protection degree of IP23.

Specifications
