Product Desciption

1, overview:
Single-phase multi-function network power meter is specially designed and manufactured for the power monitoring requirements of power supply and distribution systems. It can measure all commonly used power parameters with high precision, such as single-phase voltage, single-phase current, active power, reactive power, and frequency, Power factor, electric energy, etc. At the same time, it also has the functions of electric energy accumulation, over-limit alarm, switch input and output, network communication, etc., and has a good man-machine interface.
Single-phase multi-function network power meters have extremely high-cost performance and can replace conventional measurement indicating meters, electric energy meters, multi-function power meters, and auxiliary units of agencies. The instrument can be used in various control systems, energy management systems, substation automation, and distribution network automation. In industrial automation, intelligent buildings, intelligent distribution boards, and switch cabinets, it has the advantages of convenient installation, simple wiring, convenient maintenance, and small engineering volume. The characteristics of the input parameters can be set on site. It can complete the networking of different PLC and industrial control computer communication software in the industry.
