Apartment rental electricity meter prepaid multi-user meter

Description :

　　Product Introduction

Function:

　　The ADF400L series multi-user electric energy meter can achieve direct measurement of 12 three-phase or 36 single-phase channels or mixed measurement of 12 three-phase transformer connection, direct connection and transformer connection through module combination. This series of electric energy meters is highly favored by residential areas, schools, enterprises, etc. due to its high accuracy, centralized installation, centralized management, high installation flexibility, and non-interference advantages. This series of instruments supports prepaid functionality.

Application scope:

　　Used for residential communities, schools, and enterprises.

Ordering Example:

　　Specific model: ADF400L-4H3S12DY

　　Technical requirements: 4-channel transformer connection+3-channel three-phase direct connection+12-channel single-phase direct connection (prepaid type)

　　Communication protocol: RS485 interface DL/T645 protocol

　　Auxiliary power supply: none

　　Technical Specifications

　　A main module can carry up to 36 circuits (12 three-phase, 36 single-phase, or a mixture of single-phase and three-phase, with no more than 36 circuits), with one directly connected

　　One three-phase or three single-phase input module is connected, and one transformer is connected to two three-phase input modules.

　　Example: Customer demand, 5 households with three-phase transformers connected, 2 households with three-phase directly connected, 5 households with single-phase directly connected, with prepaid.

　　Selection instructions: First, determine if the number of circuits is greater than 36. One transformer is connected to two three-phase modules, so the connection of five three-phase transformers needs to be done according to the

　　According to the calculation of 6 three-phase circuits, there are a total of 18 circuits of 6 * 3; Two households with three phases directly connected to a total of 2 * 3=6 circuits; A direct access module with three single-phase channels, therefore 5

　　Direct connection of household single-phase requires calculation based on 6 single-phase circuits, totaling 6 circuits; Overall, the total number of circuits is 18+6+6=30<=36.

　　Product model: ADF400L-5H2S5DY

　　Module composition: Due to one transformer module with two three-phase channels, 5H requires three transformer measurement modules, and 2S requires two directly connected measurement modules

　　Module, one directly connected module with 3 single-phase channels, so 5D requires 2 directly connected measurement modules. Overall, this model of product includes one main module,

　　3 transformers connected to the measurement module, 4 directly connected to the measurement module

　　Product features

　　Multi user meters have only been developed in recent years. Compared to traditional meters, multi-user meters have more comprehensive functions and are more widely used in our daily lives. Now let's take a look at the significance of multi-user meters.

　　1. Multi user energy meters save energy. Compared with previous energy meters, multi-user energy meters have the characteristics of household metering, centralized collection, cycle display, small size, high accuracy, safety and reliability. They can simultaneously achieve mixed metering of single/three-phase circuits and high-power electricity consumption, effectively eliminating energy waste.

　　2. Multi user energy meters save space. Multi user energy meters can be used for multiple households and integrate electronic and computer technologies. It has a small size and can accommodate a large number of households (the area of a 24 household cluster meter is about one-third of that of a simple centralized installation with a single meter), and some multi-user meters can currently accommodate 39 households. Of course, this is also related to the magnitude of the current. At the same time, it also has the function of "one household, one meter". It is worth mentioning that there is currently a type of fully electronic intelligent multi-user energy meter on the market, which uses a single-chip microcontroller as the core and adopts a fully modular structure. It can simultaneously measure the electricity consumption status of multiple users and independently monitor the electricity consumption status of each user. It displays the cumulative electricity consumption or remaining electricity consumption of each user in a loop, saving space and achieving metering.

　　3. Multi user energy meters reduce the occurrence of electricity theft. Multi user energy meters can achieve household detection, centralized installation, and centralized management, and fundamentally eliminate various theft and leakage phenomena, reducing many electricity disputes and accidents. Taking the current multi-user electricity meters in the market as an example, a single meter can control the electricity consumption of multiple households. The outer shell is reinforced and locked, and only the property management or relevant personnel have the corresponding keys to open it. Other personnel cannot open it. In addition, the internal structure is equipped with corresponding anti-theft functions to prevent this phenomenon.

　　4. Multi user energy meters reduce fire hazards. Multi user energy meters reduce fire hazards. Taking university dormitory apartments as an example, the current commonly used electricity meters on the market are model based multi-user meters. The main functions of this multi-user energy meter include anti theft, prepayment, remote meter reading, remote control, overload protection, timed power cutoff function, and malicious load identification.
