  • Four Capacitive Couplers, each charged by their own dedicated circuit.

  • The CouplerTec module incorporates a microprocessor that employs a process called ‘Monitored & Controlled Performance’ – This is where the microprocessor monitors and controls the performance of the system, ensuring that it is operating at the optimum level. The module confirms that it is working correctly by way of a Green flashing LED, giving you peace of mind that your vehicle is being protected. Conversely, the system will also indicate the detection of a fault by way of a Red flashing LED. The system will reset after the fault has been rectified.
