英文介紹
The SM852B phase sequence indicator is a highly efficient tool for detecting phase sequences and power status in three-phase electrical systems. It can quickly determine the phase sequence, open phase status, and voltage parameters of power sources, making it suitable for industrial equipment debugging, power system maintenance, and electromechanical installation.
This product utilizes intelligent detection technology to automatically identify the phase sequence of R/S/T three-phase voltages and provides detection results through intuitive LED indicators and audible signals. The working voltage range is 60V to 600V (three-phase AC), with a maximum withstand voltage of 2000V per minute and a pulse voltage of 4000V. The measurable frequency range is 20Hz to 400Hz. When reverse phase sequence or open phase conditions are detected, the device immediately triggers audible and visual alarms to help operators quickly locate issues.
The SM852B features a compact ergonomic design with a high-strength engineering plastic housing that is both lightweight and impact-resistant. The three measurement probes are treated with special processes to ensure good insulation and stable contact. The included portable storage case facilitates the organization and transportation of the tool and its accessories, meeting the mobility needs of on-site operations.
