Product Introduction

Microcomputer relay protection tester is in reference to issued by the ministry of the type of microcomputer relay protection test device technical conditions (discussion paper), on the basis of widely to listen to your users, summarizes the current domestic similar products strengths and weaknesses, full use of modern advanced microelectronics technology and the implementation of a new type of device miniaturization of microcomputer relay protection tester. Microcomputer relay protection tester with a large screen LCD display and flexible and convenient rotating mouse controller. Stand-alone operation has a strong function, can carry out most of the tests, connected to the computer operation has a more powerful operation function. Small size, high accuracy. Not only has the large tester superior performance, advanced function, but also has the small tester compact and flexible, easy to operate, high reliability, performance and cost. It is a good tool for the maintenance workers.

Product names:microcomputer relay protection tester, microcomputer relay protection tester, three phase relay protection tester, relay protection tester, three phase relay protection tester, three phase relay protection calibrator, relay protection calibrator, three phase relay protection calibrator, relay protection tester
