WL-J Multi User Prepaid Smart Energy Meter
JX type ladder control type electric energy meter with multiple rate electric energy meter RS485 network/RF card network communication
FEATURES
The electric meter adopts advanced metering and control chips (industrial grade), modular structure design, and strong anti-interference ability.
The meter box has a small volume, with regular and neat internal wiring that meets the requirements of power distribution. It is easy to install, maintain, and upgrade.
The communication circuit of the electric meter adopts lightning protection circuit, and the signal adopts photoelectric isolation. The communication circuit is separated from other circuits of the electric meter for processing, which can minimize the damage of lightning strikes to the electric meter.
The interface of the electric energy signal acquisition module adopts a computer specific interface, which has undergone special processing to ensure reliable signal transmission.
The metering circuit and communication/display circuit adopt a dual CPU structure, with one CPU responsible for metering and the other for communication, display, and indication. Communication does not affect metering.
The internal strong and weak electricity are isolated by galvanized shielding plates, which can reduce the interference of strong electricity on weak electricity signals.
The internal power supply is three-phase, but the power supply is out of phase, and the electricity meter works as usual;
The incoming terminal of the electric meter adopts dedicated wiring terminals, which have strong current carrying capacity and are convenient for on-site construction.
◆ Data Security: Various data parameters of the electricity meter are encrypted using encryption algorithms to ensure data security.
◆ It can simultaneously measure and detect 36 households (39 households) of single-phase or 12 households (13 households) of three-phase, as well as any combination of single-phase and three-phase for households below 36 households (39 households).
◆ Equipped with power phase loss indication function;
Function Description
◆ Prepaid (countdown) function; Users need to purchase electricity first before using it, and there are various payment methods available for power outages due to overdue payments;
Overload protection (current limiting) function: When the user's load exceeds the maximum allowable load, the user automatically loses power protection.
◆ Power off automatic recovery function: After user overload power off protection, within the specified number of power outages, if the maximum power used by the user drops to the allowable range, the system can automatically restore power supply.
◆ Allow overdraft power function, which can be set according to the user's reputation. If the overdraft power exceeds the set parameters, the power will be cut off due to overdue payments.
◆ Set tiered electricity consumption and tiered unit price function: The monthly electricity consumption can be divided into multiple stages (up to 4), and corresponding unit prices can be set accordingly; The higher the electricity consumption, the higher the unit price, guiding users to save electricity.
Four types of rate unit prices can be set, and electricity billing can be implemented during peak, off peak, off peak, and off peak periods.
The function of saving electricity usage records can save the user's electricity usage history for three consecutive months, and the monthly settlement time can be set (1-28 days); The monthly settlement content includes: the time range of electricity consumption, the cumulative electricity consumption in each stage, the tiered electricity consumption and electricity price setting values implemented in each stage, and the electricity consumption fees for each stage.
