Purpose:

JBC-III Relay Protection tester is newly developed high intelligent, multi-function relay calibration equipment. The instrument uses single-chip microprocessor technology over the same period by the number of milliseconds the table automatically, logic control unit, multi-function digital display unit, high-precision data acquisition and processing unit, current, voltage output unit, overload and over-range protection unit and other components, since with print and display, automatic testing process, greatly improve the accuracy and efficiency.

The instrument also has a beautiful appearance, reliable performance, easy operation, function is complete, the advantages of protection devices is the ideal calibration instrument.
