The user side consumes 80% of the electric energy of the whole power grid, and the intelligent power management of the user side is of great significance to the user's reliability, safety, and saving of electricity. The intelligent power service system is constructed to promote the multi-function energy meter intelligent energy management terminal and other equipment power management solutions to realize the two-ways positive interaction between the power grid and the user. The research contents that the client needs to solve mainly include: advanced meter, intelligent building, intelligent appliance, value-added service, customer power management system, demand-side management, and so on.
Acrel intelligent multi-function energy meter with an intelligent energy management system to help customers achieve real-time monitoring, high-precision electrical parameters acquisition, easy to install.
VERTESZ Electronics Ltd. focuses its attention on the market segments of industrial electronics; One is telecontrol (SCADA projects) of medium voltage secondary distribution network by TELPAM product range. The customer installs Acrel ADL400 multi-function three-phase watt-hour meter in the distribution cabinet, connects with the gateway through RS485 communication mode, and connects the uplink Ethernet to the server. Feedback the collected information to the management platform in real-time.
ADL400 is a smart meter designed for power supply systems, industrial and mining enterprises, and utilities to calculate electricity consumption and manage the electric demand. It features high precision, small size, and simple installation. It integrates the measurement of all electrical parameters with the comprehensive electricity metering and management provides various data on previous 48 months, checks the 31st harmonic content and the total harmonic content, realizes the remote communication and the remote control with switching input and relay output, and boasts the alarm output. It is fitted with an RS485 communication port and adapted to MODBUS-RTU Protocol. ADL400 can be used in all kinds of control systems, SCADA systems, and energy management systems. The meter meets the related technical requirements of the electronic meter in the IEC62053-21standards.
