.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.
