Art. nr: 418991

Description

Comfort functions like defrosters and seat heaters require a lot of power from the battery. Modern vehicles also depend on advanced electronics that increases the load on the battery. A normal driving pattern will not keep the battery sufficiently charged over time. Routine charging is necessary to prevent the battery from becoming discharged and degraded.

DEFA On-Board Smart Charger 1203X is designed for modern 12V battery technology (no Li-Ion), and actually extends the life span of the battery. This charger has an internal relay function to control the DEFA engine and interior heaters, and is primarily designed for passenger cars and light trucks.

With a temperature sensor and sophisticated software, 1203X offers a perfect charging curve in all climates and an automatic boost mode for charges up to 5A/14.7V, especially when it gets cold. The new body design of the charger offers high quality resistance to water and dust intrusion.

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 and drops 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 cabin 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.

MultiCharger 1203X is included in WarmUp Bluetooth assemblies.
