ENTF-M
ENTF-M Intelligent reactive power controller
Product overview:
ENTF-M is a flexible modular intelligent reactive power automatic compensation control system, which includes two basic components: basic unit and expansion module. As the main component, the basic unit mainly completes the functions of data acquisition, communication and logic control. It is the core of the whole system. It can communicate with the expansion module or intelligent switching switch through a unified communication interface, collect the input signals on the expansion module or intelligent switching switch through communication, and control the opening and closing operation of the expansion module or intelligent switching switch. This architecture optimizes the control before switching various switches and capacitor banks, greatly improves the flexibility of various reactive power compensation schemes, and greatly reduces the switching, operation and maintenance costs of reactive power compensation system.
Product features:
The distributed IO module with temperature monitoring can directly control the conventional switching switch, which is not limited by the hardware of a single controller;
At the same time, it supports three-phase common compensation, partial compensation and hybrid compensation;
The color touch screen can help users operate the controller conveniently, and the menu navigation and parameter setting are quite simple and intuitive;
Through RS485 communication, various intelligent switching switches, intelligent capacitor modules, SVG devices or APF devices can be controlled or coordinated;
Support cloud data storage and analysis to facilitate users to master power quality data at any time;
Total electric quantity measurement, THDu and THDi can be measured at the same time, sub harmonics can be measured, the maximum harmonic number can reach 31, and sub harmonics can be displayed by histogram;
Adjust the power direction by adjusting the CT polarity on site;
Low voltage protection, overvoltage protection, harmonic over limit protection, over temperature protection, external emergency stop protection.
