A three-phase cost controlled smart electrical meter is a power metering device with functions such as prepayment and remote control. To distinguish three-phase cost controlled smart electrical meters, the following aspects can be taken into account:
1、 Appearance features
Display screen: Three phase cost control smart electrical meters are usually equipped with LCD screens, which are used to display information such as electricity level, electricity bill, remaining amount, etc. The clarity, brightness, and amount of information displayed on the screen can serve as a reference for determining its level of intelligence.
Prepaid system: The three-phase cost control smart electrical meter has a prepaid function, so there may be signs or buttons related to the prepaid system on its appearance, such as recharge card slots, query buttons, etc.
Communication interface: Three phase cost control smart electrical meters are usually equipped with RS485, Infrared and other communication interfaces to achieve remote meter reading, remote control and other functions. These interfaces may appear on the appearance of the electrical meter in the form of sockets, ports, etc.
2、 Functional Features
Prepaid function: This is one of the most prominent features of three-phase cost controlled smart electrical meters. Users need to purchase electricity first before they can use it. This function can be determined by observing whether the electrical meter has functions such as recharging and checking the remaining power.
Remote control function: The three-phase cost control smart electrical meter supports remote control, such as remote power outage, power restoration, etc. This can be verified by operating the management system or APP that is compatible with the electrical meter.
Electricity limit management: Three phase cost control smart electrical meters can set electricity limits. When the electricity consumption reaches the limit, the electrical meter will automatically shut down or issue an alarm prompt. This function can be determined by observing whether the electrical meter has limit settings, alarm prompts, and other functions.
3、 Application scenarios
Three phase cost controlled smart electrical meters are commonly used in places that require prepaid management, such as households, commercial buildings, enterprises, etc. These places usually have strict management requirements for the use of electricity, requiring accurate measurement of electricity and timely settlement of costs.
In summary, by observing the appearance, functional characteristics, and application scenarios of three-phase cost controlled smart electrical meters, it is possible to accurately distinguish this type of meter. At the same time, you can also refer to the product manual of the electricity meter or consult professionals for more accurate information.
