OR3F Small Relay Protection Tester 4 Phase Voltage 3 Phase Current
OR3F Relay Protection Tester
I. Product introduction
OR3F relay protection tester is controlled by a high-performance industrial computer, with built-in Windows platform software, and can also be operated externally through a computer. Adopting high fidelity and high reliability modular linear power amplifier, the output waveform is smooth.It can output standard 4-phase voltage and 3-phase current, and has a built-in independent DC output dedicated power supply. The switch node configuration is rich, with 8-way contact input and 4 pairs of blank node output. The advantages of small size, high precision and complete protection function have further improved the cost performance of the instrument.
