DY-KA DC switch ampere second characteristic tester

This instrument is designed specifically for testing, inspection, and maintenance work in substations. Satisfy the overload and short-circuit characteristic testing of DC circuit breakers, thereby improving the health level of the DC system in substations and avoiding the occurrence of over class tripping and large-scale power outages in the DC distribution network.

Features

Switching constant current control technology, new power devices, self setting constant current output from 1A to 500A;

Suitable for ampere second characteristic testing of rated current 1A~500A DC circuit breakers and 6A~100A DC fuses;

The measurement method adopts full point testing or spot testing, with fast response speed, high testing accuracy, safety and reliability;

It has overheat, overcurrent, and overvoltage protection functions, good electromagnetic compatibility, and strong anti-interference ability;

The test management software can automatically complete the testing of the ampere second characteristics of DC circuit breakers, and analyze the test data to draw the protection characteristic curve of the circuit breaker

And generate report output.
