Intelligent Watt-hour Mete

1、Product Summary
The three-phase electronic ammeters with multi-function of DTS72 and DTS71 series are one of new generations to enter the market, with some other international advantages. We have taken a lot of redundancy design for the reliability of the products. They are applicable to grid situation of all domestic areas. Various technical indexes in accordance with national standards and industry standards. They have the features of high-precision measurement, steady and reliable performance, long life, small size, low power consumption, simple operation, easy to implement the expansion of management functions, multi-function and so on.
Product models
Features and application
DTSD71-type used in machine room with smart integrated Power watt-hour meter
specially made for communication equipment room and BS
The electricity will be measured respectively.
All the dynamic parameters are included.
Surge-resistant design are more suitable for communications equipment room.
It can measure in different time and provides exact basic data for saving energy.
You can choose the power supply at the basis of your own demand. (~220V or DC48V/24V)
There can be 4 fee rates intercalated all day
The circumstances of blackout and lack of phase will be recorded.
Dedicated communications room, the base station customization
DTS72-type used in machine room with smart integrated Power watt-hour meter DTS72
Three-year freeze on electricity monthly and one-year freeze on electricity daily
You can make use of the short message module for long-distance communication.
Interface for infrared meter and interface of RS485 can be allocated to improve the efficiency of extracting data.
The magnification of the transformer can be set through the handhold device for reading the data on meter. And it can reduce the difficulty of construction and improve the efficiency of the construction.
Custom designed for power management
