Product Description
1. Product IntroductionNR1200 microprocessor-based protection relay test set is adopted advanced structure, which can run independently on the machine or connected with a laptop or computer to operate. The host computer is equipped with a new generation of high-speed digital signal processor, a true 16-bit DAC module, a new modular high fidelity high-power amplifier, a large screen LCD and a flexible and convenient rotating mouse controller. Stand-alone operation has a strong function, can carry out most of the tests, connecting computer operation has more powerful operation functions. Small volume and high precision. It not only has the superior performance and advanced function of large-scale tester, but also has the advantages of small-scale tester, such as small size, flexible, simple operation, high reliability, and high-performance price ratio. It is a good tool for the replay protection workers.2. Technical parameters
