Three-phase sequence tester, SM852B, 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 rotating magnetic fields, providing an efficient solution for electrical professionals. Technical Specifications Precise fault and phase sequence detection via LED indicators and an audible alarm Continuous battery life: up to 60 minutes at 200 V AC and up to 4 minutes at 600 V AC Maximum withstand voltage: 2,000 V per minute (4,000 V pulse voltage) Measuring frequency range: 20 Hz to 400 Hz Battery-free design, energy-saving and environmentally friendly Operation 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.
