Product Introduction
The LDZKC-1000A DC Circuit Breaker Ampere-Second Characteristic Tester is specifically designed for substation testing, maintenance, and repair. Utilizing automatic control technology, DC high current generation technology, and high-speed sampling technology, it can measure and verify the overload protection trip time, short-circuit protection trip time, timed return time, and coordination between the upper and lower circuit breakers of micro or molded-case dedicated DC circuit breakers in power DC power supply systems. It features accuracy, safety, and reliability. The testing process strictly adheres to the GB14048.2-2008, GB10963.2-2008, and DL/T5044-2004 standards, thereby enhancing the health level of substation DC systems and preventing large-scale power outages caused by malfunctions, misoperations, and oversteps in the DC distribution network. The system is highly praised by users for its accuracy, safety, reliability, and aesthetics.
