Main technical features

The main technical features of KD-ZKH type electric energy meter

※ Diversified charging methods: According to user needs, they can choose to pay in advance or pay after before placing an order.

※ 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.

※ Multiple low battery alarm functions: The alarm battery level can be set. When the user's electricity consumption is below the set value, three methods can be used to remind the user to purchase electricity: window flashing, SMS reminder, and dynamic LED screen display.

※ Allow overdraft power function: Depending on the user's reputation, different overdraft power limits can be set. If the limit is exceeded, the power will be cut off due to overdue payments.

※ Timed power-off (switch) function: Divide a day into multiple time periods (up to 8), set the on/off status of each time period, and achieve timed power on/off control for users

Dual circuit (KD-ZKA II) and triple circuit (KD-ZKA III) power supply function: Users can divide the room's electricity consumption into multiple circuits according to the actual situation, and each circuit can be controlled and managed independently.

※ Free battery gift function: It means giving users a certain amount of battery free of charge every month and adding it to the remaining battery.

※ Malignant load recognition function: Considering the safety of electricity use, the product is equipped with malignant load recognition function. This function can effectively control malignant loads (malignant loads: purely resistive heating appliances that are prone to fire and other hazards, such as fast heating, electric furnaces, electric pots, etc.) without affecting the normal (allowed) use of electrical appliances.

※ Night low power limit function: Set the night load parameters, making it convenient for users to use low-power appliances (such as battery chargers, etc.) at night

※ Permitted load function: Multiple resistive licensed loads (up to 8) can be set, and once set, they will no longer be restricted by load recognition, making it convenient for users to use special electrical appliances normally

※ Power outage event recording function: The electricity meter will record the last power outage time and reason for each household, making it convenient for users to query and manage.

The public electricity allocation function allows the system to allocate public electricity by household or number of people. (Only applicable to postpaid models)

Month end arrears freeze function: After the monthly settlement, users with arrears will be subject to power consumption restrictions. Free electricity can be set, and after monthly settlement, if the monthly electricity consumption is less than the free electricity, there will be no frozen power limit; When the electricity consumption exceeds the set free electricity consumption, the user's electricity consumption restriction will be frozen before payment. After payment, the electricity consumption restriction will be lifted. (Only applicable to postpaid models)

management style

※ Hybrid mode: Combining RS485 bus network with RF card mode.

※ Network mode: Managed by computers through transmission networks such as 485 bus network, local area network, wireless network, telephone network, GPRS network, fiber optic network, etc.

※ RF card method: Users can purchase electricity, send electricity, and perform user information queries, statistics, and other operations through RF cards.

※ Infrared handheld terminal method: Management personnel sell electricity on-site through infrared handheld terminals.
