Automotive Surge Protection and Electronic Protection Devices

During welding work on the vehicle or when charging the vehicle’s built-in battery, voltage spikes or elevated voltages may occur in the vehicle electrical system. Electronic and surge protection devices are designed to limit or absorb such voltage spikes, thereby protecting sensitive electronic components in the vehicle.

Autotestgeräte Leitenberger offers the ES 01 for 12-V electrical systems and the ES 02 for 12- and 24-V electrical systems for this purpose. The ES 02 automatically detects the on-board voltage and is therefore suitable for both passenger cars and compatible commercial vehicle applications.

In addition, the NSV 03/1 for 24-V vehicle electrical systems combines voltage maintenance with an electronic protection function. It can supply power to the vehicle via an external 24-V power source during battery replacement and also offers pulse spike suppression to protect the vehicle’s electronics.

When performing any work, the specifications of the vehicle, battery, charger, and, if applicable, welding equipment manufacturers must be followed.
