Easy and Low-Cost Measurement
■Simple Measurement/Installation
The built-in LCD screen enables the settings, measurements, and displays required for
measuring energy with a single unit.
■Product Lineup that Provides Easy Equipment Selection
This measuring unit lineup consists of a "High Performance Model" and a "Standard Model".
High Performance Model: For customers who want to perform harmonic measurements, alarm monitoring,
①
upper/lower limits monitoring, alarm output and pulse input/output, in addition to the Standard Model features
Standard Model: For customers who "want to start measuring energy in a simple and low-cost manner".
②
■Specialized Cable is Not Required
You can use a general-purpose cable between the measuring unit and split current sensor!
Cost can be reduced because no specialized cable is required.
* EMU2-CB-Q5B(-4W) is necessary if using a split 5A current sensor.
* Refer to "Wiring Precautions" on p. 26 for information about general-purpose cables.
