This module is a regulated 13.8Vdc power supply with built-in 1.5A current limiting. It can serve as a 12V lead acid battery charger that starts charging when the battery voltage decreases below 13.8V. The charger can be left to trickle charge 12V lead acid batteries indefinitely, even when the batteries are not used. It can also be used with solar panels to charge 12V batteries. It stops charging when the battery voltage is more than 13.8V (fully charged).
Technical data:
- Input voltage: 16...20V= (solar panel or power supply)
- Output: regulated for charging a 12V accumulator to max. 13.8...14.2V
- Output current: 0...1.5A, depending on the charging state of the accumulator
- Dimensions: approx. 60 x 46 x 20 mm
