5. Areas of Application
The meter can be used as a data acquisition unit for an Intelligent Power Distribution Automation System or a Plant Automation System that integrates process instrument and electrical requirements. The available serial communication option allows for fast and simple integration with these systems. The Meter is also suitable for any AC applications where there is considerable distortion of current wave form from nonlinear loads such as a VVVF Inverter, Ballasts and Switching Power Supply.
