Product No: WB2671B
The WB267* Series AC/DC Withstand Voltage Tester is specially designed for high-voltage safety inspection of electrical products. Its core function focuses on AC/DC withstand voltage testing (some models specialize in AC withstand voltage testing). By accurately applying high voltage and monitoring breakdown current, it evaluates the insulation strength and breakdown resistance of the Device Under Test (DUT), and efficiently identifies safety hazards such as insulation layer damage, circuit short circuits, and creepage.
The entire series comes standard with preset voltage/time, fast overcurrent protection, automatic discharge, and acousto-optic alarm functions. Some models support remote control. With a simple and intuitive operation interface, it not only meets the high efficiency requirements of batch testing on production lines but also adapts to the accuracy needs of compliance verification in laboratories. It is a core high-voltage safety testing equipment covering multiple fields including household, lighting, industrial, and medical.
