LED Digital Voltmeter for Real-Time AC Voltage Monitoring
The digital voltmeter with red LED display shows you the supply voltage at any time, without additional instruments. It is mounted directly in the electrical panel or control panel through a 22mm hole. Ideal for industrial installations, automations, and control panels where continuous voltage monitoring prevents equipment failures.
What you get with this product
- Read the voltage instantly on a visible LED display from a distance, without a multimeter or external devices
- Quick installation in a standard 22mm hole in any panel, with secure threaded screw fastening
- Works across the entire AC 12-500V range — compatible with residential and industrial installations
- Minimum consumption under 20mA — does not overload the network and does not generate additional costs
- High-brightness red LED display, readable in any ambient light conditions
- Durable construction with flame-retardant casing, tested for over 30,000 hours of continuous operation
How it works and how to install it
The digital voltmeter measures the AC voltage from the network and displays it on the LED screen in real time. Installation is done by inserting the component into the 22mm hole in the panel, securing it with the nut on the back, and connecting two conductors to the marked terminals. No calibration is required — after connection, it immediately displays the voltage value. It operates continuously, without interruptions, as long as the network is powered.
Frequently Asked Questions
Does it measure DC voltage or only AC?
The voltmeter exclusively measures AC voltage, in the 12-500V range. It is not compatible with DC voltage.
How large should the hole in the panel be for mounting?
The hole must have a diameter of 22mm, standard for panel components. It is secured with the nut from the back.
Is the display clear in bright light or in the dark?
Yes, the red LED has a brightness of over 60 cd/m², which ensures excellent visibility in all lighting conditions.
