AC/DC Withstand Voltage Test System

The WB267* series AC/DC Dielectric Strength Test System is engineered for high-voltage safety verification of electrical products in compliance with international standards. Its primary function is AC/DC dielectric strength testing (with specific models optimized for AC dielectric strength testing). Through precise application of high voltage and continuous monitoring of breakdown current, this system evaluates the insulation integrity and dielectric strength of the Device Under Test (DUT), effectively identifying safety-critical defects including insulation degradation, circuit short circuits, and surface creepage. The WB267* series incorporates standardized features including programmable voltage/time parameters, rapid overcurrent protection, automatic discharge circuitry, and audible/visual alarm systems. Select models support remote control operation. Featuring an intuitive operational interface, this system satisfies both the throughput requirements of production line batch testing and the precision demands of laboratory compliance verification. It serves as essential high-voltage safety testing equipment across multiple sectors including consumer appliances, lighting systems, industrial equipment, and medical devices.
