Digital Voltmeter for Alternating Current (AC) – Compatible with Single-phase and Three-phase, Blue LED Display
High-performance digital voltmeter for measuring voltage in alternating current (AC) systems, both single-phase and three-phase, with clear LED display, easy calibration, and no external power required.
This digital voltmeter is specially designed for measuring voltage in alternating current (AC) systems. It works efficiently in single-phase systems, measuring voltage between phase and neutral, as well as in three-phase systems, measuring voltage between any two phases. It is powered directly from the measured voltage, without requiring an external source.
Main Features
- Compatible with alternating current (AC) for accurate voltage measurement
- Measurement in single-phase systems (between phase and neutral)
- Measurement in three-phase systems (between two phases)
- Directly powered from the measured voltage, no external supply needed
