Type: EXR50

Description

The EXR50 is a so-called voltage monitor. By means of an in-built microcontroller, the on-board electrical network voltage is permanently monitored. As soon as the charge status of the vehicle battery becomes critical, the EXR50 automatically disconnects the load. This ensures that the vehicle battery is not discharged by comfort consumers such as a cool box, fan, coffee machine, laptop, smartphone, etc. to such an extent that the engine can no longer start.

  • Continuous monitoring of the on-board electrical voltage.
  • No vehicle breakdowns due to weak batteries
  • 12 V version for passenger cars and 24 V version for trucks

This voltage monitor is suitable for standard automotive relay sockets to ISO 7588 (ISO MINI). With its mechanical contact system, the EXR50 is designed for continuous currents of 10 A, 30 A and 40 A.
