Single phase relay protection tester Products Description
Overview
This high-performance, lightweight field tester features an attractive aluminum alloy chassis and PC panel. Equipped with an ARM chip controller, its LCD displays real-time voltage, current, and stopwatch data. It provides one fully isolated and adjustable AC/DC voltage and current output channel, along with an additional adjustable DC voltage output channel. The output circuit includes dual overload protection. Combining high output capacity with a compact size, light weight, and high reliability, it is ideal for field calibration and characterization testing of various relays.
