The Multi-user Pre-paid Electricity Meter from Yongnuo Electrical (Leqing) Co., Ltd. is a new pre-paid electricity meter designed for up to 39 single-phase or 13 three-phase users (can also be a mix of both phases on a single meter). It uses high-frequency radio frequency cards (MI cards) for data transmission, offering advantages such as contactless, anti-attack, large capacity, good encryption, stable data transmission, and long service life. The meter can also be connected via RS485, allowing up to 256 meters to share a single card reader. After purchasing electricity, users don't need to swipe a card at the meter; they can automatically retrieve each user's electricity consumption information through a computer at any time, facilitating timely statistics of monthly electricity consumption for management purposes. It is an ideal product for electricity metering and control in enterprises, urban residential complexes, student dormitories, old building meter upgrades, and high-rise buildings.
Product Features
Cyclic display of each household's electricity consumption, with clear and intuitive presentation.
Multiple users on a single table, multiple counts on a single table, merging multiple tables into one
Direct and external mixed supply, with external supply first, followed by direct supply; three-phase mixed with single-phase, with three-phase first and single-phase last.
Adopting dualCPU architecture, powerful functionality, superior performance
Features remote meter reading with computer technology
Easy installation; installation location unaffected
Case shell is single stamping formed, with good sealing properties.
The circuit is powered by a three-phase power supply, and it can still measure normally even if one phase is missing.
Utilizing dedicated terminal blocks, dual-bolt wiring, for safe and reliable operation.
A single multi-user electricity meter can simultaneously provide single-phase and three-phase outputs.
The signal employs optical isolation, separating communication lines from other circuits to mitigate the damage to the meter from lightning strikes.
Utilizing high-precision current transformers, operates without heat generation, excellent electrical isolation, strong overload capacity, and long service life.
Communications interface functions can be provided upon customer request, facilitating the integration of electricity consumption data into their existing management information system.
