MULTI POWER MONITORING EXTENTION UNIT
(clamp-on current sensor type CLSE use)
Functions & Features
• Multi power monitoring unit for Modbus (model: R9MWTU)
• Multi power monitoring unit for Modbus/TCP (model:
R9EWTU)
• Extension unit for Multi Power Monitoring Unit (model:
R9xWTU) to expand current inputs.
• Clamp-on current sensor (model: CLSE)
The clamp-on current sensors, not included in this product
package, must be ordered separately. Required number
depends upon the system configuration.
• By using clamp-on current sensors, there is no need of
current transformers.
• Up to 16 circuits can be measured with R9xWTU.
(Common voltage measurement)
• Current sensors are easy to install in existing systems.
Wide input range of 5 to 600 A is availabe.
