Product introduction
UHV-316N Intelligent Power-Frequency Withstand Voltage Tester is suitable for power-frequency withstand voltage tests of various single/three-phase AC/DC electric motors, transformers, and electrical coils. It complies with relevant technical requirements in national and industrial standards, featuring complete functions, convenient operation, safety, and reliability. Output voltage or capacity for special specifications can be customized according to user requirements.
Product Features
(a). Equipped with a color LCD touch screen, guided prompt operation, and self-diagnosis function, ensuring convenient and intuitive operation.
(b). Supports multiple parameter storage groups, allowing separate setting of test parameters and storage of test data and results.
(c). Displays real-time test values, as well as real-time curves of measured voltage and leakage current.
(d). Adopts electric voltage regulation for test voltage output, with complete overvoltage protection.
(e). Output voltage can be preset; uses approaching voltage regulation algorithm to reach the set value, and maintains stable voltage output during timing.
(f). Automatically alarms audibly and visually, cuts off high voltage, and resets the electric voltage regulator to zero if the test object's leakage current exceeds the set value, providing complete overcurrent protection.
(g). Real-time grounding protection detection: testing is prohibited or terminated if grounding is unreliable, ensuring personal safety.
(h). Equipped with a micro printer for printing stored test data and results.
