1  The high-performance 32-bit processor provides powerful computing processing, profect circuit design, and industrial-level components to ensure stable and reliable operation.

2  Unique component level - engineering level - user level，three level programming mode, component type can be set on site. The digital input and relay output are programmable.

3  High-speed and high-precision AC signal measurement with sampling frequency up to 1600Hz. Multiple channels AC signal FFT calculations are done in milliseconds. Sampling values are digitally corrected and can effectively suppress noise and offset.

4  A powerful vectorization calculation algorithm can obtain a variety of derived AC signal characteristics, including positive, negative, zero sequence, phase-to-line transformation, angle, impedance, power and so on.

5  The device is capable of continuously recording 64 events, with a full event record of the protection action with fault time, type, and peak value.

6  Graphic LCD（128x64）, can display graphics, icons and full English&chinese display.

7  The main signal process circuit is equipped with an electromagnetic interference absorbing element to meet the working environment in a harsh electromagnetic environment.

8  The enhanced MODBUS-RTU communication interface can transmit real-time waveforms, vector data, etc. in addition to normal data.

9  Complete self-test function, including tuning parameters, recording, operation loop, current, voltage loop and other abnormal monitoring.

10  The fully enclosed thin metal chassis is waterproof and dustproof, and has strong anti-static and electromagnetic interference capability; it can be installed on the switch cabinet in a distributed manner, and can also be grouped.

11  SMT technology, important components (such as power supply modules, transformers, relays, LCDs, terminals, etc) adopt mature products from well-known enterprises at inboard and abroad to ensure that the average running time more than 100,000 hours.
