1.1 Description of EV/DV300
Powerful and Economical
EV/DV300 series power meter is designed for three phase electrical parameter
measurement by using of latest microprocessor and digital signal process
technology. It can True-RMS measure Voltage, Current, Power, Reactive Power,
Power Factor, Frequency and Energy. The meter can be well used in high harmonic
environment especially in middle and low voltage power system, electric
apparatus, power system automation and factory automation. All the measuring
electrical data are available via digital RS485 communication port running
ModbusTM Protocol. The meter also got some flexible I/O ports that made the
metering, monitoring, remote controlling and Analog output in one unit possible.
This can save large cost for user in setting up electric power automation system.
Small Size & Easy Install
EV/DV300 series was designed in compact size DIN96*96 and reduced depth
60mm. It is suitable for small cabin installed in switch gear. Easy install and remove
on panel by using clips.
Display Clear and Easy to Use
Large character LCD characters with blue back light made the display easy to read
even under the dark light. All the Value reading and parameter setting can be
access by using 4 panel keys or communication port. The meter parameters are
protected in EEPROM, which will maintain its content after the meter is power off.
High Level Reliability and Safety
Multi-isolation and anti-interference methods were adopted in the EV/DV design
according to the industry standards. The meter can be installed in hazard industry
area. Also the meter was tested under IEC standards and EMC standards. The
meter house was design by using glass polymer which is durable and inflaming
retarding.
