Product Details

Step by step electricity meter:

“The full name of "tiered electricity price" is "tiered progressive electricity price", which refers to setting the average household electricity consumption into several tiers. The first tier is the base electricity facility quantity, and the electricity quantity within this tier is relatively small, resulting in a lower electricity price per kilowatt hour; The second tier has higher electricity consumption and higher electricity prices, while the third tier has more electricity consumption and higher electricity prices.

Functional Features:

1、LCD display, with clear and intuitive display content.

2、Using encryption cards andDESDynamic encryption algorithm ensures secure and reliable system data.

3Adopting high-power magnetic holding relays, with strong overload capacity and sensitive and reliable action.

4After inserting the card, the function of writing back the meter parameters is designed rigorously and will not cause any electricity disputes.

5、High precision, stable performance, low self power consumption, anti-theft, no need for calibration for long-term use.

6Network electricity price change function: When the electricity price changes, it can be done through485The network transmits the new electricity price information to the electricity meter.

7Control power on/off function: through485The property management department can control the power on and off of users' electricity meters without leaving their homes through the internet.

8Step by step electricity pricing function: According to the requirements of the local electricity management department, any step can be set up to achieve tiered billing based on usage.

9、Power outage alarm function:When the remaining power does not reach the set alarm value, the electricity meter automatically shuts off to remind users to purchase electricity in a timely manner.

10Network meter reading function: equipped with485Interface, which can retrieve the electricity consumption of each meter at any time, facilitating the management department to calculate monthly electricity consumption.

11Load control function: When the load exceeds the set value, the electricity meter automatically shuts off, and the load decreases5The electricity meter will automatically restore power supply in about minutes.

The DDSY825 prepaid electricity meter has multiple anti-theft functions. The DDSY825 prepaid electricity meter has a small starting current, no creep, wide load, and low power consumption. The error curve of the DDSY prepaid electricity meter is straight and stable during long-term operation.
