CHARGE AMPS Charge Controller/Charger DC-DC SRNE 12V 20A 300W

The CHARGE AMPS Charge Controller/Charger DC-DC SRNE is a high-efficiency DC-DC battery charger designed for 12V systems in RVs, caravans, marine, and off-grid vehicles. It converts input voltage from 9-16V DC to a regulated 12V output, delivering up to 20A (300W) to charge and maintain auxiliary batteries. With support for multiple battery chemistries and intelligent multi-stage charging, this unit ensures optimal battery health and performance.

Advantages

This charger features >97% efficiency, reducing energy loss and heat generation. Its compact design with intelligent fan cooling allows for reliable operation in temperatures from -35°C to +65°C. The common negative grounding simplifies installation, while comprehensive protection (input over/under voltage, output over voltage, over temperature, reverse polarity, output short circuit) safeguards your system.
