UNI-T UT261B Phase Sequence and Motor Rotation Indicators
The UNI-T UT261B is a handheld, battery-powered device designed for identifying phase sequence and motor rotation directions in three-phase systems. It helps in verifying the correct phase orientation and the direction of motor rotation, which are critical in industrial applications. This compact tool is essential for ensuring the proper operation of three-phase motors and electrical equipment.
The instrument is robust and portable, equipped with multiple indicators to provide clear visual feedback on phase sequence and motor rotation. The test leads connect to the system’s phases, and the instrument automatically determines the phase orientation. It features a non-contact motor rotation testing mode, useful for both single-phase and three-phase motors.
The UT261B is designed for ease of use with a simple power button and indicators for clockwise and counterclockwise rotation. It is built with safety in mind, including multiple protection features like double insulation and warnings for hazardous conditions. The device is durable and can withstand minor impacts, making it suitable for use in rugged environments.
