Three-phase AC phase tester with LED indicator, buzzer, and clip. Suitable for transformers, inverters, and other devices (60V-600V). Compatible with

【Two Functions】This three-phase AC phase sequencer has two functions: an indicator to verify the correctness of the phase sequence and an indicator to show whether the phases are open or not. This function allows for easy verification of the operating status of the circuit and phases.

【LED Indicator】The LED indicator is a key feature of this phase indicator. When the phase sequence is correct, the LED indicator shows green and emits an intermittent beep. When the phase sequence is reversed, the LED indicator shows red and emits a continuous beep.

【20Hz-400Hz Measurable Frequency Range】It's easy to use. Suitable for three-phase AC voltages, it can measure frequencies from 20Hz to 400Hz. Simply connect this phase sequencer to the circuit to measure the phase state, making it very suitable for various practical application scenarios.

【With Clip】Safe and reliable design. Equipped with a clip that easily contacts circuit terminals, ensuring the safety and reliability of measurements. Users can use it with peace of mind and feel a greater sense of security.

【60V-600V Three-Phase AC Voltage】A wide voltage testing range is the main feature of this three-phase AC phase sequencer. It can detect three-phase AC voltages from 60V to 600V with excellent performance. It can accurately test and display the phase state in both low-voltage and high-voltage situations.
