Product Description

 

The KDCW-20 device is designed for the Class II product combination wave test requirements of the SPD in the low-voltage power distribution system. It can generate impulse voltage (1.2/50μs) and impulse current (8/20μs) for the Class III test and limiting voltage test of SPD and components. It can also perform impulse current tests and residual voltage value verification on MOV valves, units and surge protectors (SPD), or be used for other scientific research tests.

The device uses computer and PLC control technology, and its main performance meets the various combination wave test requirements for SPD products and their devices at home and abroad.
