For Standard type and Advanced type

  • Resolution of integral active power measurement from 0.01Wh; which helps you to monitor detail data of shorter period.
    * For RS485 communication only. (Display data range of KW9M has not been changed.)
  • 115,200 and 57,600 bps are added to RS485 transmission speed for high speed data collection.

Features

Large-screen LCD with backlight clearly displays the electric power of each phases and their total on one screen.

Large-screen LCD with backlight clearly displays the electric power of each phases and their total on one screen.

Capable of displaying small currents of 1 mA or above.

This allows for the monitoring of standby power consumption, which helps energy saving.

Capable of displaying small currents of 1 mA or above.
* Capable of measuring 0.1 % or higher the rating of the secondary side of CT.

Capable of simultaneously measuring up to three circuits in a single phase two-wire system of same power supply.

Capable of simultaneously measuring up to three circuits in a single phase two-wire system of same power supply

Data can be made visualization by connecting the meter to DLL* and logging the data.

Alarms can be e-mailed to mobile phones or other equipment.
*DLL is the abbreviation for Data Logger Light.

Data can be made visualization by connecting the meter to DLL* and logging the data.

You can measure power with a direct connection to an already-installed large-capacity general-purpose CT (secondary side 1 A / 5 A type).

* The dedicated CT for Eco-POWER METER® cannot be used. Use a CT with a secondary side current of 1 A / 5 A.

The measuring accuracy of the Eco-POWER METER® does not take the CT error into account. Other Eco-POWER METER® series (except AKW8115) need to use two CTs for measurement. KW9M is ready for direct input from only one CT, allowing higher accuracy measurements than with other Eco-POWER METER® series.

You can measure power with a direct connection to an already-installed large-capacity general-purpose CT (secondary side 1 A / 5 A type).

Free visualization software for supporting energy management

Free software to create graphs from data collected by DLL for energy management.

  • Cumulative bar charts by equipment and pie charts
  • Comparison graphs by time and equipment
  • Numeric display function
  • Auto graph updating function
* KW Watcher cannot simultaneously display values of three phases in graphs.
(Up to two graphs for comparison can be displayed.)

Configurator KW9M supports easy setup on PC of KW9M

Configurator KW9M

■Set or change of the setting of KW9M Eco-POWER METER

  • As you can set up several units at one time, setting time is reduced.
  • You can readout the setting value from a unit and copy the setting to another unit.
  • You can select register No. and set it up.

■Monitoring and logging function of measuring values on KW9M Eco-POWER METER

  • Monitoring and logging of measuring values are available.

Configurator KW9M

Demand measuring function compliant with IEC61557-12 effective for energy saving

* 30-min demand method is also selectable for use in Japan. (Advanced type)

IEC demand (Sliding block interval and Fixed block interval)
Users set the time span for demand calculation to an arbitrary value between 1 to 60 minutes (in increments of one minute).
The average power demand within the set span is calculated at the end of the span. [The demand values of active, eactive, apparent, active (export), and reactive (export) power are calculated.]

Sliding block interval method

・Sliding block interval method
The next time span starts “n” minutes later. (Value "n" is arbitrarily set by users.)

Fixed block interval method

・Fixed block interval method
The next time span starts after completion of the current span.

System configuration

System configuration
* Also ready for CT inputs (electric power measurement)

Harmonic measurement [Advanced type]

Inverter equipment and fluorescent lighting fixtures are harmonic sources and can have adverse effects on precision equipment, thereby causing it to malfunction.

Harmonic measurement
*Standard type unit is equipped with THD measurement function only.

Measurement of interphase unbalance [Advanced type]

If there is an unbalanced load due to a V-connected transformer or a heater, a voltage imbalance occurs between phases, and the motor torque becomes insufficient, causing a rise in heat or reduction in product life.

Improvement of between phases unbalance

The advanced type is also capable of N-phase measurement using the fourth CT. [Advanced type]

The advanced type is also capable of N-phase measurement and electric leakage detection using the fourth CT.

Equipped with input and output terminals [Advanced type]

Two pulse input points
Simultaneously measures data including that other than electric energy (production amount, flow rate, etc.).
Capable of time synchronization by inputting a clock setting trigger

Two pulse output points
The PhotoMOS output allows for connection of NPN input and PNP input devices.
Ready for alarm outputs, which are frequently used.

Equipped with input and output terminals

Various log functions available
