JGDL-63 is an energy metering type current limiting protector, which provides multiple protection functions for overvoltage, undervoltage, overcurrent, leakage, temperature, frequency, and energy meteringThe comprehensive protector of Neng can set all protection
JGD multi-functional power meter is designed for the power monitoring needs of power systems, industrial and mining enterprises, public facilities, and intelligent buildings. It can measure all common power parameters, such as three-phase current, voltage, active and reactive power, electricity, harmonics, etc. Because the power meter also has a complete communication networking function, we call it a network power meter. It is ideal for real-time power monitoring systems. The meter has a high performance-to-price ratio and can directly replace conventional power transmitters and measuring instruments. As an advanced intelligent and digital front-end acquisition element, this series of network instruments has been widely used in various control systems, SCADA systems and energy management systems
The product adopts DIN35mm rail installation structure, small size, can measure electric energy and other electrical parameters, can set parameters such as clock, rate period, etc., with high precision, good reliability, and performance indicators in line with the national standard GB/T17215-2002, GB/T17883-1999 and the power industry standard DL/T614-2007 for the technical requirements of the electric energy meter, and has the function of electric energy pulse output; RS485 communication interface can be used to realize data exchange with the host computer.
Fault arc protector: hereinafter referred to as the protector, effectively detects the fault arc in the access line, including the fault parallel arc and the fault series arc, and when the fault arc that causes fire is detected in the line, the power off function can be carried out to achieve the purpose of early warning of fire. The fault arc protector is suitable for electrical circuits of 10KW and below in industrial and civil buildings
Intelligent current limiting type over-under-voltage protector is a set of: over-voltage, under-voltage, over-current protection functions of a comprehensive protector, product modular, intelligent, visualized, product over-voltage, under-voltage, over-current protection, all protection parameters can be set, when the line over-voltage, under-voltage, over-current and other faults occur the protector can instantly cut off the power supply, protect the electrical equipment intact and not damaged.
After 10 years of technical precipitation, N times of testing and technical improvement, JGGQ-80 self-resettable over-under-voltage protector is on the market, using high-speed micro-low-power processor as the core of the control circuit, magnetic latching relay as the main circuit, and modularized standard design, which has the technical advantages of low power consumption, precise control, beautiful appearance, anti-harmonic, anti-interference, and withstand voltage up to AC450V.
D85, D69, D91 series is a small volume of economical digital electrical measuring instrument, mainly used for real-time measurement of AC voltage, DC voltage or AC current, DC current in the electrical circuit, and with LED digital tube or LCD liquid crystal in digital direct reading mode. It is widely used in substation automation, distribution automation, testing equipment, generators, and so on. The product has the advantages of high precision, high stability, high reliability, low power consumption, small size, easy installation, and LCD has the advantages of clear backlight display, etc., which is an ideal product to replace various pointer electric measuring meters.
JGFH-JS series is a three-phase four-wire current-limiting protector is a comprehensive protector with a variety of protection functions such as overvoltage, undervoltage, overcurrent, leakage, phase loss, and lack of zero, and the advantages of product modularization, intelligence, visualization, etc., while supporting the standard Modbus485 communication protocol, all protection parameters such as overvoltage, undervoltage, and overcurrent protection can be set according to the power demand to ensure that overvoltage, undervoltage, and overcurrent occur in the line
