3-in-1 Digital Indicator for Complete Electrical System Monitoring
This digital voltmeter-ammeter-frequency meter helps you instantly check the status of AC electrical circuits without separate instruments. Ideal for electrical panels, control panels, or monitoring the consumption of industrial equipment, it simultaneously displays voltage, current, and frequency on a visible LED display.
What you get with this product
- Simultaneous monitoring of voltage, current, and frequency on a single display — eliminating the need for three separate devices
- Excellent visibility regardless of ambient light — powerful yellow LED, clear reading even from 2-3 meters away
- Simple installation in a standard 22mm hole — integrates directly into existing electrical panels without modifications
- Rapid detection of electrical problems — instantly identify overvoltages, undercurrents, or abnormal frequencies before they affect equipment
- Current transformer included in the package — complete kit for measuring up to 100A, no additional purchases
- Robust construction for industrial environments — shock and vibration resistant casing, continuous operation without degradation
How it works and how to install it
The indicator measures voltage directly from the AC 60-500V circuit, while the attached toroidal transformer measures current up to 100A without interrupting the circuit. The tricolor LED display simultaneously shows all three parameters, updated in real time. Installation involves inserting the body into the 22mm hole in the electrical panel, then connecting the cables according to the included diagram. The current transformer clamps onto the phase conductor without requiring disconnection. Installation requires certified electrician qualifications according to safety standards.
Frequently asked questions
Can I use it for single-phase 220V household networks?
Yes, it works perfectly with household 220V AC, measuring voltage between 60-500V and current up to 100A, covering both residential and industrial installations.
Is it necessary to cut the power to measure amperage?
No, the included toroidal transformer clips onto the phase conductor without interrupting the electrical circuit.
What does it mean that the LED light is visible from a distance?
The yellow LED display emits powerful self-light, making the values clear to read even in bright spaces or from positions 2-3 meters away from the panel.
