Functional characteristics
Ultra-small integrated aluminium alloy chassis
32-bit CPU, 16-bit AD, realize 32-point sampling of weekly wave, high sampling accuracy, 2% precision of protection current, 0.2% precision of voltage, AC/DC wide-range auxiliary power supply, working range AC or DC86-275V.
Supporting multiple communication protocols
6-way switch (4 of which can be set as non-electric input), passive contact input, 4-way relay output, and 1-way RS485 communication interface
Display
Chinese/English Wide Temperature LCD Display with Resolution 128*64 and Static Power Consumption less than 5W
High Anti-interference
Through 10 EMC certifications (fast transient, electrostatic discharge, surge anti-interference, etc.).
It provides the measurement function of system parameters at measurement level, and the measurement accuracy is better than that of measuring instruments at the same level, but it can not be used as measurement. The system mainly adopts two-meter method. Besides providing basic measurement parameters such as current and voltage, it also provides the measurement of active power, reactive power and power factor, etc. When the ratio of CT and CT is changed, the primary value can be displayed, which can replace the digital measuring instrument.
Multiple Protection
It can upload remote signals of switch quantity, protection function pressure plate, fixed value area code and accident alarm. At the same time, the switch is equipped with remote control to switch on and off, the soft pressure plate of the protection function is thrown back, and the fixed value of the protection is modified, and the fixed value area is switched over.
