1.1 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

No.	Variables	Unit	Direction	Display (Max.)	Accuracy
1	Current	A/kA		9.999 kA	Class 0.2
2	Active Power	kW/MW	Directional	20mA	Class 0.5
3	Reactive Power	kVar/MVar	Directional	20mA	Class 0.5
4	Active Energy	kWh	Directional	999999.99 MWh	Class 1.0
5	Reactive Energy	kvarh	Directional	999999.99 Mvarh	Class 2.0

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)

The measured parameter unit is displayed on PC as follows
