Charger Assembly 1203X

1203x On-Board Smart Charge with Harness, Mounting bracket and foam

Art. nr: 453013


The charger assembly allows your business to reduce costs in components and storage while offering comprehensive vehicle coverage. For this reason we have made 3 assemblies where the difference is just the length of the 12V harness. All charger assemblies include rings of various diameters to fit most North American battery fitments.

DEFA pays a lot of attention to detail, for this reason we have also provided in this assembly an aluminum bracket for easy and long lasting installation, as well as foam patches to insulate the charger from any possible contact with hard parts that might generate vibrations and noise.

SmartCharge 1203X Features:

  • Modern switch-mode technology preserves your battery and allows the charger to be permanently connected.
  • Temperature compensated charging ensures that your battery is charged in all conditions.
  • LED indicator for charging mode and quick charging mode (green and red).
  • If the battery experiences sufficient load during trickle charging to drop the voltage below 13V, the charger automatically switches to full power mode (quick charge).
  • Short-circuit protection and reverse-polarity protection. This requires installation of the fuse included with the charger.
  • 120V recognition prevents the relay from staying on and discharging the battery when the charger is not in use.
  • 2 relay controlled outputs for engine and parking heaters which can be activated with a time program control unit (external signal).
  • Will not damage the vehicle’s electronic systems.
  • Compact dimensions.
  • Prevents battery degradation (sulphating) and extends the lifetime of the battery.
  • Prevents release of harmful gases.
  • Comes with a waterproof socket.
