Keep Battery Voltage in View 

Add a compact voltage display to a compatible DC installation. This digital panel voltmeter brings a three-digit LED readout to a vehicle, boat or electronics project, making the measured voltage visible at a glance.

Key Benefits

• LED digits — Read the voltage on a dedicated panel display.
• Two-wire design — Use a compact connection format for the planned circuit.
• Display-color options — Choose the listed red, green or blue version.

Instead of reaching for a separate meter every time you want a reading, integrate a display into the project itself. Match the installation to the specified operating range and wiring instructions.
