Let me take you to understand this product: PIR-GY protection device (hereinafter referred to as protective devices), with the 6kV, 10kV voltage level, the maximum rated current up to 400A of the shift change supporting the use of high-side switch, in order to achieve the power supply system various protection functions. Protection device uses an advanced microprocessor, high-precision data processing and advanced protection algorithms, protection of high precision, fast response. Complete undervoltage, overvoltage, overload protection features, short circuit, temperature measurement, test. My company is a new generation of protection, to overcome the previous generations of defective products, recommended. Using high-end CPU processing speed, advanced algorithms. The protection function parameters can be selected by the Chinese menu to adjust for a wide range, high precision protection. Protector smaller, more features and modular structure, optimize hardware and software interference treatment, with a friendly interface, making installation, use, maintenance easier, life greatly increased. Protector and LCD one, highly integrated, Chinese display; with menu-driven man-machine interface, easy operation. Real-time display of the current system of three-phase current and voltage in operation, the information-rich. Reserve / expansion abundant resources; high detection / protection accuracy. New temperature protection transformer temperature monitoring, and the action point temperature is adjustable. Future communications interface; stable and reliable, users can choose to add. ???????
