3. Product characteristics
(1) Flexible combination of voltage current output
NR802 is with 4-phase voltage and 3-phase current output, that can carry out combination of various types of output protection testing easily. Each phase voltage can output to 120V, the trip-combination current can output to 120A, the fourth phase voltage Ux is the multi-function that can be set to four kinds 3U0 or synchronization voltage, or other certain voltage output.
(2) Easy stand-alone operation
Device panel set a trackball mouse, optimized keyboard and large-screen TFT LCD, built-in a full set of English windows platform operating software. Boot to use, easy to operate.
(3) Dual operation mode
In addition to the stand-alone operation, the device can connect with laptop and desktop computer to operate. The two operation functions are exactly the same, and truly dual operation mode.
(4) New high-fidelity linear amplifier
The output terminal always adopts modular linear amplifier with high-fidelity and high reliability, not use switching amplifier. Testing on site will not generate medium or high frequency interference, and guaranteed the smooth and precision waveform which from high-current to small-current.
(5) High-performance of host
The output part adopts DSP control, high speed of calculation, powerful real-time digital signal processing capability, widely transmission frequency, controlled high-resolution D/A converter. High precision of output waveform, good linearity distortion. Adopting lots of advanced technology and precision components materials, and with professional structural designed, which make the device small, light, full-functions, easy to carry, boot to use, and the flow testing is very convenient.
(6) Powerful software function
It can complete a variety of large and complex calibration task with highly automation, that can test and scan varies protection value easily, make fault recurrence, real-time storing of test data, display vector and online printing reports. 6-phase can test three-phase differential protection conveniently.
(7) Separate and special DC power output
802 Series setting 110V and 220V special adjustable DC power output. With separate dedicated DC power output 802 device has a special way adjustable DC 110V and 220V power supply output.
(8) Complete interface
The device panel has a built-in keyboard and mouse, can be stand-alone operating, and also operating by connected keyboard and mouse, beside there are USB interface and RS232 interface, that can connect with computer and other external devices.
(9) Perfect self-protection
Self-protection
Adopting reasonable cooling structure, with a variety of reliable and comprehensive protection measure and soft starting power, and some self-diagnostic and interlocking function.
(10) Light & highly integrated stand-alone and unitary structure
Adopt a large number of well-designed ultra-light and high-tech smart structures, which make the machine extremely light and small.
