DTE-20M with DTE-6 current injector AC/DC

DTE-20M primary current injector AC with DTE-6 DC current injection test kit

The purpose of DTE-20M with DTE-6 is designed for high AC and DC current injection for testing DC relays and circuit breakers. The test kit is split into two modules: 1) Control unit with current transformer; 2) AC/DC converter. AC current output uo to 20 kA, DC current output - up to 6 kA.

DTE-20M primary current injector with DTE-6 DC current injector is a mobile device, which could be easily transported to a required testing location. Built in timer and ammeter. Thermal and short-circuit protection.
