Multi Power Transducer
Model: M50EXWTU
OEL display clearly displays information
The OEL display allows you to check the measured values of voltage, current, power, energy, CO2 emissions (energy conversion value), and relative harmonic content of each element, as well as various setting values.
The display turns off if a set time elapses without any button operation. Just press any button while the display is off to return to the state before the display was turned off. You can also set the display to always be on.
Installation
Compact size
Multi Power Transducers, featuring the 41 mm (1.61 in.) deep (55 mm or 2.17 in. for M50EXWTU), terminal block style housing, are suitable for installation in a tight space of breaker boxes or wall-mounted panels.
Compact modules can be squeezed into a minimum open space found in existing panels.
Multi Power Transducer can be retrofitted
*1. Excluding M50XWTU-U. For details, please see the User Manual.
Easy installation with clamp-on current sensors
The current inputs are connected in one touch by using Clamp-on Current Sensors (Model: CLSE), needing no live cable modification.
Furthermore, the M5XWTU and M5XWT use the voltage input to drive their internal circuits, needing no auxiliary power supply connection.
Clamp-on current sensors can be retrofitted with no power line modification
*2. For the M50XWTU-U, use the clamp-on current sensor dedicated to the product (Model: CLSE-U).
Clamp-on current sensor
The one-touch clamp-type sensor, incorporating a nylon spring, can be easily installed on existing equipment, such as distribution boards.
5 A, 50 A, 100 A, 200 A, 400 A, and 600 A types are available.
| Model | Applicable wire diameter | Operational range |
| CLSE-R5 | 10 dia. max. | 5 A max. |
| CLSE-05 | 10 dia. max. | 50 A max. |
| CLSE-10 | 16 dia. max. | 100 A max. |
| CLSE-20 | 24 dia. max. | 200 A max. |
| CLSE-40 | 36 dia. max. | 400 A max. |
| CLSE-60 | 36 dia. max. | 600 A max. |
Settings and Connection
The built-in CPU calculates the AC power variables instantaneously
The built-in CPU calculates instanta- neously up to 290*3 variables for three-phase/3-wire system, including momentary values such as current, voltage, power, average values, maximum and minimum values, total harmonic distortion, and the 2nd to 31st harmonic contents, before updating the measured data in the memory every 500 milliseconds (approximate cycle).
*3. 104 variables for M5XWT (three-phase/3-wire), excluding harmonic contents.
Modbus communication
Modbus communication, convenient for remote energy monitoring by PLC or data loggers, is selectable as standard. Monitoring points can be easily added by daisy-chain wiring of twisted-pair cables.
Other output options such as analog signal, energy count pulse and alarm contact*4 are also available for direct input to PLC/DCS.
*4. Options for M5XWTU. Modbus only for M5XWT. Modbus plus energy count pulse signals are available for M50XWTU, M50EXWTU, and M50XWTU-U.
Free setup software tool with convenient functions
The PC Configurator Software is used to set up various parameters of the Multi Power Transducer. It has a convenient monitoring window showing all measurement values in real time.
The loop test output mode, in which any output value can be simulated without actually connecting to active input circuits, is useful for system commissioning.
• PMCFG is downloadable for free from Software Download & Upgrade.
Setup via Modbus communication
Using the PC Configurator Software to set the device address to the Multi Power Transducer in advance makes it possible to configure settings remotely via Modbus communication from a LAN-connected PC.
Built-in loop test output function
Loop test output mode in the PC Configurator Software can be used to simulate any output value without actually connecting to the active input circuits, which is useful for system commissioning.
Incorrect wiring and disconnection checking
The vector chart in the PC Configurator Software can be used to visually check for incorrect wiring and disconnections.
・Monitoring window for M5XWTU
Convenient for periodic inspections
The PC Configurator Software makes it possible to record items that are not constantly monitored—such as harmonics and power factor—during periodic inspections, and the recorded data can then be used for predictive and preventive maintenance.
・Monitoring window for M50XWTU
Tension-clamp terminal block
Wiring to the tension-clamp terminal block is quick and easy. Ferrules, solid or stranded wires of up to 1.5 mm2 can be used.
Single module can measure up to 4 circuits!
Space-saving and economical.
4 x single-phase/2-wire circuits
1 x single-phase/3-wire + 2 x single-phase 2-wire circuits
Three-phase/3-wire 2-circuit
Three-phase/ 4-wire 1-circuit
・Please see data sheet for more connection/application examples.
Applications
You can start a single- or multi-point power monitoring system with the Modbus.
Precise power management is essential to achieving carbon neutrality. You can install the Multi Power Transducers in a small space, even on existing equipment.
You can start with a small budget and gradually increase the number of measurement points, extending to overall management. For example, using Web Data Logger (Model: DL30-G) may be ideal as it enables Modbus communication at a reasonable cost.
