A multi-user electric meter is a fully electronic, intelligent, multifunctional electric power meter, with a microcontroller at its core. It employs a fully modular structure, enabling simultaneous measurement of electricity consumption for multiple users. It independently monitors each user's electricity consumption and cyclically displays their usage. It also supports both wired and wireless communication methods for management. It can facilitate individual metering, centralized installation, and centralized management, fundamentally eliminating various theft and leakage phenomena, reducing many electricity-related disputes and accidents.
Product Features
Cyclic display of each household's electricity consumption, with clear and intuitive presentation
Multiple households on a single table, multiple calculations on one table, merging multiple tables into one.
Direct connection and external power supply mixed, with external power supply first, followed by direct connection; single and three-phase mixed, with three-phase first, single-phase last.
DualCPU architecture, powerful functionality, superior performance
Remote meter reading with computer functionality
Easy installation; installation location unaffected
The housing is formed in a single stamping operation, ensuring good sealing properties.
The circuit is powered by a three-phase power supply, and it can still accurately measure even if one phase is missing.
Utilizing dedicated terminal blocks, dual-bolt wiring, for safe and reliable operation
A single multi-user electric meter can simultaneously provide single-phase and three-phase outputs.
The signal employs opto-isolation, separating the communication lines from other circuits to mitigate the damage to the meter from lightning strikes.
Utilizing high-precision current transformers, operates without heating, offers excellent electrical insulation, strong overload capacity, and long service life.
Communications interface functions can be provided upon customer request, facilitating the integration of energy consumption data into the customer's management information system.
