Parameters
with Modbus communication.
Single Phase Parameters: Voltage,
Current, Power,
Reactive Power, Apparent Power, Power Factor,
Frequency and
KWH in a standard 1/8 DIN package. Standard
RS485 communications capable. Economical choice when monitoring and measuring are
required. No metering over kill. Single phase defined as 1
hot lead up to 500V, 1 Neutral.

Data
EV-190
|
The EV100 single phase
meter may be used as a data gathering device for an
Intelligent Power Distribution Automation System or a Plant
Automation System that integrates instrument and electrical
requirements. All monitored values are available via RS485
comm. port running the Modbus protocol.
Not UL listed. Accuracy is revenue grade. |
