.1 Description
DEM8900-1/DEM8900-2/DEM8900-3 (short form for DEM8900) is designed by adopting the updated microprocessor and digital signal processing technology, which can be applied for monitoring the electrical system. DEM8900 can measure and analyze the real time electrical parameters, such as I,kWh,kvarh., Meanwhile, DEM8900 has functions of multi-tariff,RS485 communication ( MODBUS protocol),analog output, remote input and electrical pulse output.
All our instruments fulfill all important requirements and regulations concerning electromagnetic compatibility and safety isolation (IEC61000, IEC1010 standard and EN61010 standard). The devices have been developed, manufactured, and tested in accordance with Quality Assurance System ISO 9001.
1.2 Measured parameters
Note 1. DEM8900-1 measure current, active energy, active power (optional, with analog output)
2. DEM8900-2 measure current, reactive energy, reactive power (optional, with analog output)
3. DEM8900-3 measure Current, active energy, reactive energy, active/reactive power (optional, with analog output)
1.3 EMC and Safety standard

Especially developed for indication and
supervision of the three-phase circuit. Provide
three-phase active power, reactive power,
power factor measurement and display, can
expand the measurement range, replaces old
analogical meter, reducing installation
manpower and optimizing the used one of
spaces in the panel.
Ideal for protection of three-phase networks is
monitored and generally to own alarm superior
and inferior. Protection of the parameters of
programming by password.
DDS5558 Single Phase Meter is a kind of new style single phase two wire active energy meter, it adopts micro-electronics technique, and imported large scale integrate circuit, use advanced technique of digital and SMT techniques, etc. It has minimum size, and also a new single phase two wire active energy meter.
