Main Features of Circuit Breaker Switch Characteristic Tester
1) The main control part adopts a high-performance industrial computer, Windows XP operating system, real-time display of various parameter curves and values.
2) Keyboard, touchpad input (external USB mouse can be connected); 5.7-inch TFT true color LCD display. Simple operation, beautiful interface, all parameters at a glance.
3) Switch constant current control technology, new power devices, 1A~500A self-set constant current output, high constant current accuracy, strong load capacity, can work stably for a long time.
4) Suitable for ampere-second characteristic testing of DC circuit breakers with rated current 1A~500A, and can also be used for ampere-second characteristic testing of DC fuses 6A~100A.
5) The measurement method adopts full-point testing or sampling point testing, with fast response speed, high test accuracy, safe and reliable.
6) The instrument has overheat, overcurrent, and overvoltage protection functions, good electromagnetic compatibility, and strong anti-interference ability.
7) The test management software can automatically complete the ampere-second characteristic test of DC circuit breakers, and analyze the test data to draw the circuit breaker protection characteristic curve (ampere-second curve), and generate report output.
8) The industrial computer comes with 4G storage space, can store test records arbitrarily, and is equipped with two USB interfaces for easy extraction and printing of test records.
9) The instrument adopts an integrated design for easy portability.
