    Product Details of UHV-803 Three Phase Relay Protection Tester

    Product Introduction

    The UHV-803 Three phase relay protection tester is a new miniaturized microcomputer relay protection tester based on DL/T624-1997 "Technical Conditions for Microcomputer relay Protection test Device" issued by the Ministry of Power, which is widely listened to the views of users, summarized the advantages and disadvantages of similar domestic products, and made full use of modern advanced microelectronics technology and devices. The microcomputer relay protection tester adopts the advanced structure of independent operation of a single machine and can also be connected to a laptop computer. The main machine adopts DSP+FPGA structure, true 16-bit DAC output, built-in new modular high-fidelity linear high-power amplifier, 8.4 inch TFT true color display with resolution of 800×600 and industrial keyboard and mouse. WindowsXP operating system, powerful. Small size, high precision. It not only has the superior performance and advanced function of the large tester, but also has the advantages of small, flexible, easy to operate, high reliability, and high performance-price ratio. It is a good tool for continuity workers.
