Digital Voltmeter with LED Display for Voltage Monitoring
This digital voltmeter indicator measures and displays real-time AC voltage between 20V and 500V, ideal for electrical panels, control panels, or industrial installations. The blue LED display offers excellent visibility even in bright light conditions, and the standard 22mm hole mounting makes installation quick and universal.
What you get with this product
- Constant monitoring of electrical voltage without external measuring devices — see the exact value at any time
- Blue LED display with large digits, legible from a distance even in brightly lit or dusty environments
- IP65 protection for the front head — resistant to dust and water splashes, suitable for industrial environments
- Simple installation in a 22mm hole — compatible with standard openings in electrical cabinets and panels
- Robust construction that supports vibrations up to 0.7g and tested at 2.5kV — long-term reliability
- Wide measuring range 20-500V AC — useful for both standard 230V circuits and three-phase installations
How it works and how to install
The voltmeter is installed by inserting it into the 22mm hole in the electrical panel, secured with the nut on the back, and connected to the two terminals (phase and neutral or two phases for differential measurement). After connection, the LED display automatically shows the measured voltage in volts, continuously updating the value. It does not require a separate power supply — it operates directly from the measured voltage.
Frequently Asked Questions
Can I measure 400V three-phase voltage with this voltmeter?
Yes, the voltmeter measures AC voltages up to 500V, covering both 230V single-phase and 400V three-phase between phases.
Is it moisture resistant if I install it in an outdoor panel?
The front head has IP65 protection against dust and water splashes, suitable for industrial environments, but the panel itself must be protected according to regulations.
Does it need a separate power supply or does it connect directly to the mains?
It does not require a separate power supply — it operates directly from the voltage it measures, simplifying the connection.
