3-in-1 AC Digital Volt, Current & Freq. Meter

3-in-1 AC Digital Voltage, Current & Frequency Meter – Red LED, 22mm Panel Mount

Product Description

The AD16-22AVHz 3-in-1 Digital AC Meter is a compact, multifunction electrical monitoring device designed to measure AC voltage, current, and frequency in a single, easy-to-read LED display.

Featuring a bright red digital display and a space-saving 22mm panel-mount design, this meter is ideal for electrical control panels, power distribution systems, industrial machinery, generators, and electrical monitoring applications.

The included current transformer (CT) allows non-direct current measurement by passing a load conductor through the transformer, making it a convenient solution for monitoring AC electrical systems.

Key Features

• 3-in-1 Measurement: Displays AC voltage (V), current (A), and frequency (Hz).

• Wide Voltage Range: Measures 50–500V AC.

• Current Measurement: Monitors 0–100A AC using a current transformer.

• Frequency Measurement: Measures frequencies from 0–100Hz.

• Bright Red LED Display: Clear, easy-to-read digital measurements.

• Compact 22mm Panel Mount: Ideal for electrical enclosures and control panels.

• Square Front Cover: Professional appearance for panel installations.

• Current Transformer Measurement: Measures current without directly routing the full load through the meter.

• Integrated Design: Combines three electrical monitoring functions in one compact device.

Technical Specifications

Applications

Important Installation Notes

• Designed for AC electrical systems only.

• Voltage measurement requires an AC input within the specified 50–500V range.

• Current measurement requires the correctly matched current transformer.

• Pass only one appropriate load conductor through the CT for current measurement.

• Installation should be performed by a qualified electrician or technician.

• Disconnect power before installation or wiring.

• This device provides electrical measurements; it is not a circuit breaker or electrical protection device.
