compactmodularautomatic

The HZJB-II Single Phase Relay Protection Tester is a portable field testing device with excellent performance. It features an elegant, polished appearance with an aluminum alloy chassis and PC panel. Controlled by an ARM chip, the tester has an LCD screen that displays voltage and current outputs, as well as a stopwatch. The instrument provides fully isolated outputs for adjustable AC/DC voltage, AC/DC current, and adjustable DC voltage. It also features double overload protection in the output loop, ensuring safety and reliability. With its high output capacity, small size, light weight, and high reliability, the HZJB-II is ideal for field calibration and testing of various relays.
