Phase Sequence Indicator 8030 Product Introduction (English)

The Phase Sequence Indicator 8030 is a professional portable instrument designed for three-phase power system analysis, providing real-time phase sequence detection with high reliability. Featuring a dual-display system combining multicolor LED indicators and LCD digital readout, this device offers clear visual confirmation of phase rotation status. Its ergonomic housing with impact-resistant casing ensures optimal performance in demanding industrial environments.

This analyzer operates within a wide voltage range of 200V to 480V AC, automatically identifying phase sequence through advanced detection circuitry. The unit provides immediate feedback through distinct audible alerts and color-coded visual signals: steady green illumination with continuous tone indicates correct phase rotation, while flashing red light accompanied by pulsed alarm signifies reversed sequence. Integrated voltage protection mechanism safeguards the device against transient surges up to 600V.

Equipped with interchangeable test probes and spring-loaded clips, the device supports flexible connection to various terminal types. The dual-power system utilizing rechargeable lithium battery and USB external supply ensures 40+ hours of continuous operation. Energy-saving sleep mode activation after 5 minutes of inactivity significantly extends battery life. Widely applicable in motor commissioning, power distribution testing, and generator maintenance scenarios, this instrument delivers efficient phase verification for industrial electrical systems.
