Stinger SVMR

The Stinger SVMR is a compact digital voltmeter designed for continuous monitoring of the vehicle’s onboard or supply voltage. Reliable voltage monitoring is particularly important for high-performance car audio systems, as it allows for the early detection of voltage drops or problems with the battery and power supply.

The easy-to-read 3-digit red LED display allows for quick monitoring of the current system voltage. Thanks to its compact dimensions, the SVMR can be flexibly integrated into the vehicle interior. It can be mounted on the surface or installed flush with trim or interior panels.

The voltmeter features an automatic on/off function and is connected via a simple 3-wire wiring harness consisting of a constant positive, ground, and a switched 12-V signal. This allows the display to be activated, for example, along with the ignition or the car stereo’s remote output.
