It has the characteristics of high reliability, small size, light weight, beautiful appearance, advanced technology, installation of 35mm DIN-rail, and has the advantages of good electromagnetic interference resistance, low self-consumption, high accuracy, high overload, high stability, electricity-stealing prevention, and long service life.
Function Description
1. Suitable for measuring AC parameters and electrical energy with rated frequencies of 50Hz or 60Hz.
2. Some chips are selected from well-known foreign brands, and the shell is made of advanced flame-retardant PC and fiberglass material.
3. The measurement data cycle interval is automatically displayed, and the instrument parameters can be modified by pressing buttons (on-site settings: device address, protocol switching, and current ratio, etc.).
4. With small size to reduce installation space, and meeting the installation requirements of any non-standard embedded or wall mounted box and terminal household distribution box. Standard 2, 4, and 7 module structure, using 35mm DIN-rail mounted method.
5. Meet the energy-saving requirement, with a power consumption of 1/3 that of traditional electronic energy meters.
6.The preferred meter for the energy consumption monitoring platform, which is the reading terminal for electricity consumption.
7. Multiple protocol selection (MODBUS-RTU and DL/T645-2007 switching selection).
8. Malignant load judgment, power reverse judgment, free selection of forward and reverse electrical energy and full power, direct connection and CT connection can be selected.
9. Cooperate with the charging platform to achieve prepaid management, and remotely control the switches’ power on/off to achieve energy-saving.
