The power load changes over time and can be described by a daily (or annual) load curve. When the power load increases significantly, it forms a peak load in the power grid, and when the power load decreases significantly, it forms a valley load. When the difference between the peak and valley values on the load curve is large, the capacity of the power generation and supply equipment cannot be fully utilized, and the operation is uneconomical.

Product Introduction

DF type multi rate multi-user energy meter is a fully electronic intelligent multi-user energy meter, with a single-chip microcontroller as the core and a fully modular structure. It records electricity consumption during peak and off peak times and charges electricity fees at different prices. It can measure multiple users simultaneously, display the electricity consumption of each user in a loop, and communicate with the upper computer management software through various communication methods. Implement the standard GB-T15284-002 Special Requirements for Multi Rate Energy Meters.

Product specification number and function

Note: The electricity consumption of multi rate meters is counted as positive, and prepayment is realized through the balance.

Technical Parameter

PRODUCT FUNCTION

*The electricity meter can be set to automatically operate in two periods, with 10 periods and 4 different rates (peak and valley) for metering and billing in each period. In addition, a holiday can be set during the period, with 10 different time periods and 4 different rates.

*The electricity meter can store four types of electricity consumption rates and total electricity consumption for the current month, the previous month, and the previous month.

*The display adopts a backlit LCD screen, and the backlight switch can be set. Can display the current period, current rate, and current time of electricity meter operation; Loop display of user account number, current electricity consumption rate, real-time power, three-phase household indication, phase loss indication, and power outage indication.

*Equipped with a power inquiry function, the inquiry button can be used to query the "peak", "peak", "flat", "valley", and "total" power of each user for the current month, including the "peak", "flat", "valley", and "total" power of the previous month, as well as the "peak", "flat", "valley", and "total" power of the previous month in February.

*An electric meter with prepaid function can recharge amounts and set alarm and overdraft amounts.

*It can remotely control the on/off status of the electricity meter and read the on/off status.

*Support DL/T645-2007 protocol communication protocol for retrieving power consumption data.

*Support broadcasting school time.

*The electricity meter can automatically freeze the electricity data according to the set settlement date.

*An electric energy meter can record the time of the last programming and the total number of programming times.
