Product Description

Product Detail
 DR-ZMK is a new type of power distribution measurement and control equipment integrating data collection,communication,reactive power compensation, power grid parameter analysis and other functions It is suitable for monitoring and reactive power compensation controlofAC0.4KV,50Hz low-voltage power distribution system.
 DR-ZMK takes high-sped digital signal processor as the core,adopts AC sampling,and the man-machine interface is displayed in Chinese characters.It is easy to operate,and has power distribution monitoring,reactive power compensation,harmonic analysis,event recording,and temperature sensor interface (standard configuration),Fan control,alarm output and other functions,adaptive frequency algorithm,the input signal changes between 45Hzand55Hz.
 The device provides RS485(standard configuration)communication port,and the communication mode supports GPRS, wireless communication,twisted pair,coaxial cable,digital radio,etc.It can also use optical MODEM and optical fiber for communication.Combined with the communication part,it can also communicate with the SCADA master station to complete various monitoring functions for the distribution line
 The installation conforms to DIN standard,embedded installation,and the front panel is made of ABS flame retardant material.
