Isolated DC-DC Chargers

Isolated models keep the input and output electrically separate. They are a good fit when two battery systems should not share a connection.

The model name lists input voltage, output voltage and current. A 12/12-18 takes 12 V in and gives 12 V out at up to 18 A. A 24/12 steps 24 V down to 12 V, and a 48/12 steps 48 V down to 12 V.

• Choose the input voltage that matches your source battery.
• Choose the output that matches the battery you are charging.
• Pick a current that fits your battery size.
