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

General DescriptionThis SM852B three-phase sequence tester is a portable AC phase rotation indicator, designed to detect faults and phase sequence in three-phase systems. Thanks to its LED indicators and audible alarm, it allows for precise detection of rotating magnetic fields.Technical SpecificationsMaximum withstand voltage: 2,000 V per minute (pulse voltage of 4,000 V)Measurement frequency range: 20 Hz to 400 HzBattery life: up to 60 minutes at 200 V AC and up to 4 minutes at 600 V ACBattery-free design: no charging required during useEnergy-efficient and environmentally friendlyOperationTo 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 the phase sequence using an LED and a buzzer.
