DM Series DC-DC charger

Charges the house battery from the vehicle or engine alternator, including Euro 6 smart alternators.

Modern vehicles often vary alternator voltage to save fuel, which leaves a house battery undercharged. The DM Series sits between the starter and house batteries and delivers a proper charging profile whenever the engine runs.

Choose the 20A or 30A model for a smaller battery bank or lighter wiring, and the 60A model for large lithium banks that need to recharge on a short drive.

Models

DM1220	12V, 20A
DM1230	12V, 30A
DM1260	12V, 60A

Features

Works with smart and variable-voltage alternators that a simple isolator can’t charge from properly.
Multi-stage charging profile suits lithium as well as lead-acid house batteries.
Silent fanless design.
Protects against over-voltage, over-current, short circuit and battery over- or under-temperature.
