1. General Description

DDS238-1 WIFI type multi-function smart energy meter is designed to measure single phase two wire AC active energy and variable parameter. The meter have WIFI communication, it can use APP for remote reading and control on/off. Its data communication rules obey the requirement of WIFI 802.11b/g/n. It is a long life meter with the advantage of high stability , high over load capability , low power loss and small volume.

The meter is manufactured complying with international standard IEC62052-11 on “Electricity metering equipment (AC) General requirements test and test conditions” and IEC62053-21 on “Static meters for active energy (classes 1 and 2)”.

2. Specification and Technical Parameters

Specification

3. Basic Features

3.1 Measuring positive & negative active energy with negative energy accumulated into positive energy,.

3.2 The meter also display real voltage , real current , real active power

3.3 Pulse LED indicates working of meter，Pulse output width 80+-20ms

3.4 Measuring active energy without calibration under long term operation

3.5 display step by step with button

3.6 it can use APP software for data reading and remoter control on/off.

3.7 it has timing control function , it can set value from APP

3.8 it can control on/off by hand through the button

4. Working principles

Single phase voltage and current are sampled from respective sampling circuit and transformed into suitable signal, which is carried into integrated circuit , then the meter output pulse signal in positive appropriation to measured power to drive LCD counter to realize energy measurement. The meter has energy pulse output for testing with pulse width of 80+20ms

5. Structure

The meter consists of a meter base, meter cover, terminal base, and terminal cover. There are lead seals on the meter cover and terminal cover. A special screw is used to fix the terminal cover on which a lead seals can be installed

6. Usage

6.1 setting button : you can push this button to check the different data display, if you push the setting button last 5s, the meter will enter into the status of waiting for WIFI distribution network. If you want to reset status of WIFI distribution network, you also can push the setting button last 10s.

6.1 Installation : The meter can be installed on a 35 mm DIN rail

6.2 The meter can not installed and used until it is checked goods and sealed before delivery

6.3 The meter should be install in the water proof box indoor or outdoor . the meter’s box should be fixed on strong and flame-resistant wall with a recommended height of about 1.8 m , where there is no corrosive gas around.

6.4 The meter should be install fully in accordance with connection diagram on the terminal cover, it is better to use copper as the leading wire for connection. All screws should be tightened.
