The CH201 is a microcontroller-based smart charge controller that is ideal for charging 12 Vdc VRLA batteries. The charger uses MPPT (maximum power point tracking) technology to safely manage amperage and voltage for optimal battery charging and longevity. It has dual inputs for use with a solar panel and/or any 15 to 50 Vdc charging source. The dual inputs provide the option for fail-safe charging. The CH201 also outputs various parameters to allow close monitoring of the battery and power usage via RS-232 or SDI-12. In your system, use the CH201 to charge your battery and supply power to your peripherals and data logger. The 12 V output is regulated and switched, with the ability to charge a 12 V battery at a rate of 10 A.
