Application:

        Model DTSD5558 three phase four wire electronic multifunction energy meter is a kind of new style three-phase four wire multifunction energy meter. The meter completely accord with relevant technical requirements of class 1 three phase active energy meter stipulated in international standard IEC 62053-21 and class1 three phase reactive energy meter in international standard IEC 62053-23. It can accurately and directly measure 50Hz or 60Hz active energy consumption from three phase four wire AC electricity net, This meter has LCD monitors shows the active energy power consumption, and there are far infrared and RS485 communication module in it. I t has following features: Good reliability, small volume, light weight, specious nice appearance, convenient installation, etc.,

Functions and features:

1- Have three tariffs, may select 12 daily period of times. You can set the date arbitrary which can automatic read the meter every month. May select single tariff function in weekend. Work with battery, keep data more than 10 years

2- There is a clock and Maintenance-free backup lithium batteries in it. Battery capacity detection and display all the time. It can keep the electricity data for 12 months. The data can be kept forever after power cut off.

3- May select cycle display (default) or push the button itemized display, we can set the cycle display, it can display 14 data at most. Can select the data which displayed. The decimal median which displayed can choose set one or two.

4- There is a polarity port of pulse output passive closed and a no polarity port of pulse output passive distant, the output rate is 10 or 100 imp/kWh (can select),Complying with standard IEC 62053-31.

5- There are far infrared and a p ort of RS485 communication data. It is use for setting and reading the meter. Set and operation have password protection, communication protocol complying with standard DL/T645-1997.

6- The LED instructions respectively power state, signal of power impulse, the direction of the trend of load current, the state rates just now and the data communications state.

7- three components measure three phase four wire active power consumption. It is nothing with direction of the trend of load current. Complying with standard IEC 62053-21.

8- Standard configuration for direct connect and use, type A connection, we can also choose another type of connection, and use CT.

9- Standard configuration short terminals cover, may select extended terminals cover, in order to protect to use electricity safely.
