HZDL5000S Three Phase Primary Current Injection Tester With Temperature Rise Function

Overview
The HZDL5000S 5000A high current generator is a self-developed test instrument that combines the advantages of similar domestic and international products. Utilizing CNC technology, it offers strong anti-interference capability. Compared with previous generation upconverters, it features low power consumption, a large-capacity self-coupling voltage regulator, and a high-permeability iron core converter, resulting in high output power, compact size, and light weight.
Primarily used for primary bus protection and various current transformer ratio testing applications, this generator is widely used in scientific research, production, and electrical testing sites across the electric power, railway, petrochemical, metallurgical, and mining industries.
