描述
?Short description:
WAGO’s 3-phase power measurement module in a DIN-railmount enclosure measures electrical data in three-phase supply networks – remotely from the control level.
Measured variables such as active/apparent/reactive power, energy consumption, power factor, phase angle and frequency can be accessed via Modbus® Interface. In addition, the measured variables can be stored on a microSD card.
Features:
Current measurement via 5A current transformer
Mobile measurement and storage of measured values on microSD card
Configuration and display of measured values during operation via configuration interface
Compact device in DIN-rail-mount enclosure saves space used for building technology
Communication of measured values via Modbus® Interface
Configurable digital signal output as pulse output
說(shuō)明:
?Additional setting options via interface configuration software
In the present network, ensure that the neutral conductor is not dangerously active!
