HZDK-500 DC Circuit Breaker Ameper-Second Characteristic Test System is designed for testing the time-current characteristics of DC circuit breakers with rated currents from 1A to 500A. It can also be used for testing the time-current characteristics of DC fuses rated from 6A to 150A.
Product Features
Can be used as a standalone device or connected to a PC.
Features a 7-inch LCD display, high-speed thermal printer, and an interactive full-keyboard operation interface for an intelligent workflow.
Utilizes power electronics control technology to generate high-current output, offering fast response, high precision, and continuously adjustable output.
Incorporates multiple high-precision sensors for automatic current range switching and a high-performance 24-bit AD acquisition chip.
Equipped with power-off storage, capable of saving up to 1000 test data sets.
Automatically saves settings; displays the previous configuration upon restarting after a power loss.
Offers optional test modes: time-current operation test and carry-current non-operation test.
In PC-connected mode, users can control the instrument, import/store test data, generate data reports, data curves, and Excel reports.
Includes built-in protection against overheating, overcurrent, and overvoltage.
Exhibits strong anti-interference capabilities and excellent electromagnetic compatibility.
