TKJB-1200 six-phase relay protection tester TKJB-1200 six-phase relay protection tester is in the reference issued by the Ministry of DL / T624-1997 basis "microprocessor-based relay test equipment and technical conditions" on , listen to the views of users, summed up the current strengths and weaknesses of the domestic like product, full use of modern technology and advanced microelectronics devices to achieve a new type of miniaturized relay protection tester. Relay protection tester uses a separate stand-alone operation, advanced structure can also join the laptop to run. Host using DSP + FPGA architecture, true 16-bit DAC output, built-in hi-fi novel modular linear power amplifier, comes with 8.4-inch 800 × 600 resolution TFT color display and high-end industrial keyboard and mouse. WindowsXP operating system and powerful. Small size, high accuracy. The relay protection tester tester has both large superior performance, advanced features, but also has a small tester compact and flexible, easy operation, high reliability, high cost performance. Following is a good tool to protect workers in handy. Products nickname computer following the security instrument, relay protection tester, relay tester, six-phase relay tester, following the security tester, six have security tester, six-phase relay calibrator, following the security check instrument, six have insurance calibrator, following the security instrument http://www.whgdmk.com/aspcms/product/2014-4-30/76.html product features 1, to meet the requirements of all on-site tests. The six-phase current relay protection tester with a standard six-phase voltage while the output current 30A / phase, voltage 125V / phase. Six-phase current in parallel up to 180A. A variety of both traditional and protection relay test equipment, but also a variety of computer protection against modern subjected to various tests, especially for transformer differential protection and automatic switching devices, testing more convenient and perfect 2, various techniques indicators fully meet the Ministry issued a DL / T624-1997 "microprocessor-based relay test equipment and technical conditions" standard three classic WindowsXP operating interface, friendly interface, easy operation; high-performance embedded industrial control Computers and 8.4-inch 800 × 600 resolution TFT color display that can provide a rich visual information, including current working status and a variety of helpful information, such as 4, the machine comes with Windows XP system restore function, to avoid system caused by the collapse of an illegal shutdown or malfunction, etc. 5, equipped with ultra-thin industrial keyboard and optical mouse, you can operate as an ordinary PC, like the completion of various operations through the keyboard or mouse 6, the main control board using DSP + FPGA structure, 16 Bit DAC output to the fundamental point can produce a weekly high-density sine 2000, has greatly improved the quality of the waveform to improve the accuracy of the tester 7, linear power amplifier using high-fidelity amplifier, both to ensure the accuracy of a small current, but also ensure the stability of a large current 8, the relay protection tester using the USB interface and PC communications directly, without any adapter cable, easy to use 9, can be connected to a laptop (optional) operation. Laptops and IPC using the same software, without re-learning how to operate the method 10, with separate dedicated DC auxiliary voltage source output, the output voltages are 110V (1A), 220V (0.6A). To provide to the relay or protection devices require the use of 11 DC Power Supply with software-calibrating function, avoiding the need to open the case by adjusting potentiometer calibration accuracy, thus greatly improving the accuracy of stability http: //www.whgdmk .com
