SM852B Three-Phase Sequence Tester, Portable AC Phase Rotation Indicator for Current and Voltage Detection

General Description

The SM852B Three-Phase Sequence Tester is a portable AC phase rotation indicator, designed to detect faults and phase sequence in three-phase systems. This portable instrument accurately identifies the rotating magnetic field, providing an effective solution for electrical professionals.

Technical specifications

• Accurate fault and phase sequence detection with LED indicators and audible alarm
• Continuous runtime: up to 60 minutes at 200 VAC and up to 4 minutes at 600 VAC
• Maximum withstand voltage: 2 000 V per minute (4000 V pulse voltage)
• Measuring frequency range: 20 Hz to 400 Hz
• Battery-free, energy-saving and environmentally friendly design

Usage

To use the tester, simply connect the supplied well-insulated auxiliary clamp to the three-phase circuit under test.The device will then indicate faults and phase sequence using an LED and a buzzer, thus facilitating the analysis of electrical systems.
