Quality first, customers first. Ji 宁浩博 mining equipment specializing in the production and sales of mining equipment protection switching products, adequate supply, complete model, low price, timely delivery, quality Three Guarantees, welcome to contact to discuss the industry, integrity is priceless, win-win cooperation . PIR-400I magnetic starter intelligent integrated protection device, is the first to make a successful design for explosive gas (methane) and coal dust coal mine intelligent multi-functional integrated protection, with 380v, 660v, 1140v voltage level, The maximum current to various types of magnetic starter 400A of supporting the use of various functions to achieve the above-mentioned power supply system. Protector uses an advanced microprocessor and infrared remote control technology, high-precision data processing and advanced protection algorithm has the advantage of protecting high precision, fast response and so on. This protection can be achieved total leakage protection switch, sub-switch selective leakage protection, leakage lockout, overload, short circuit, phase imbalance (including off-phase), undervoltage protection and other features. Split design, flexible installation. Applicable to the common good 5-500A current levels selectable data communication interface and control system connection. According to user needs can be equipped with RS-485/232 interface. Used modular structure protection, anti-jamming hardware and software optimization and has a friendly interface, making installation, use and maintenance easier, life greatly increased. Has been in operation for five years in order to stabilize the market by adjusting the menu to select a wide range of application, protection and high accuracy. Has a "memory" function. The protection function parameters are adjusted every memory saved, the next power-up or system to automatically extract the parameters set by the last reset. Moreover, the protector can remember fault information, including the last fault type, fault time, three-phase current value when a fault occurs, the system voltage values ??are saved, you can tune out the menu display. Easy maintenance. Has the hardware and software self-test function, if the problem, the system gives the appropriate error message. You can easily perform remote control / control functions through the door near the button. Stable performance, simple operation. Using 10 × 5 Chinese character LCD 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. The protection function parameters can be.
