Product No: LS-RVT-2000W
The LS-RVT-2000W Residual Voltage Tester (Residual Voltage Tester / Peak Power-Off Device) is a specialized instrument focused on detecting residual voltage in electrical equipment. It can disconnect the tested equipment from the mains voltage at voltage peaks, and maintains sufficiently high insulation resistance after circuit disconnection to simulate a plug-and-unplugged scenario. The instrument accurately measures the residual voltage after power failure, supports multiple cyclic tests, automatically records test data and calculates relevant statistical values, and features audible and visual alarms. It can promptly cut off the voltage when the detected value exceeds the set range, providing accurate and reliable testing support for verifying the safety performance of electrical equipment.
