Product Description
CG series power monitoring instrument is designed for the power system, industrial and mining enterprises, public facilities, intelligent building power monitoring needs. It can measure all the commonly used power parameters, including current, voltage, frequency, power factor, active power, reactive power, active energy, reactive energy, etc.; with switching input and output, power pulse output and R S485 communication interface, can realize the remote transmission of data. And can be equipped with analog output, harmonic content analysis, complex rate power statistics, event recording and other functions.
The series of products have been widely used in energy management systems, substation automation, distribution network automation, community power monitoring, industrial automation, intelligent buildings, intelligent switchboards and switchboards.
The display magnification, communication address, baud rate, etc. can be set through the buttons on the panel, which is very flexible and convenient to use.
0~20 mA or 4~20 mA analog output.
Alarm output, monitoring the upper and lower limits of the measured parameters.
R S-4 85 digital interface, using standard M O D B U S-R T U protocol.
Switch input, can monitor the system switch status.
Digital calibration zero, digital calibration, high precision, cost-effective.
