Discription

The SLQ-5000AS Primary Current Injection Tester is an advanced electrical testing instrument independently developed by our company, incorporating modern numerical control technology and strong anti-interference capabilities. Designed with a high-capacity autotransformer voltage regulator and a high-permeability iron-core converter, it delivers high output power while maintaining a compact, lightweight, and portable design. The tester is primarily used for testing and calibrating thermal relays, motor protection devices, contactors, circuit breakers, air switches, switchgear, and protection panels. It also supports primary busbar protection testing and current transformer (CT) ratio measurement. With its reliable performance and versatile testing capabilities, the SLQ-5000AS is suitable for research, manufacturing, maintenance, and electrical testing applications across the power, railway, petrochemical, metallurgy, and mining industries.
