1 Phase LCD Energy Meter DS-1

It's the smallest AMR meter in the world with multifunction. It is popular in West European as its standard installation with DIN EN 50022, small size, RS485 as well as multi-functional, which is the ideal solution for residential and commercial installations.

Features

• The meter can read these data during the definite time period and analysis the quality and load condition of user's grid.
• DIN RAIL standard installation size.
• Only 18mm wide, can up to 100A.
• RS485 communication, Protocol: IEC1107 or Modbus-RTU Mode.
• Multi-tariff function. The user can set time period through RS485 communication, then the meter will measure the energy of each different time period.
• Meter has 3.6V Lithium battery, which is used to support multi-tariff function. And the precision of RTC is better than 0.5s/day.
• Blue LCD backlight allows the meter to be read in low light conditions.
• Display current and voltage.
• Accurately measure forward and reverse energy.
• Reactive energy can be measured.
• The data can be displayed through 2 methods:

1. Display data automatically by page and the time interval is 5s.
2. Check data through the external button.

• Material of Meter housing: ABS fire resistant.
• Degree of Protection: IP51 (indoor meter).
