Recommended energy saving solution!
Measurement, data management,
and visualization of energy
usage made easy!
Data
Collection
made easy!
Automatic Saving to SD Memory Card!
Measurement data is automatically saved to an SD
memory card.
Data collection is possible without a network.
• Data can be saved at intervals of 1, 5, 10, 15, 30, or 60 minutes.
• Previous power usage is displayed on screen (up to 8 days worth).
• Lithium battery backup eliminates worries during power outage.
• Data is stored to memory of main unit when an SD memory card is not
inserted.
Visualization
made easy!
Simply Insert SD Memory Card into PC!
Measurement data that is saved to the SD card can be
easily displayed in graph form using the free KW View
software tool.
• No complicated settings are required. Data from
multiple KW2G-H units can be compared in a single
graph.
• In addition to electrical power, create comparison
graphs for pulse/analog data loaded by an expansion unit
(pulse input type / analog input type).
Measurement
made easy!
Simply Connect a Current Transformer (CT)!
Using the easy measurement mode, simply attach CT to the
target power cable that you want to measure.
Electric power measurement is possible without having to turn
the power off of existing equipment.
100 V AC

• It is possible to measure electric power even if it is not possible to
wire the power source to be measured.
Easy system expansion with add on modules
Eliminate excess wiring by using up to seven expansion units to add-on the required number of
CT inputs for your application.
• Power measurement, pulse input, and analog input expansion units are available for increased application
coverage.
8 units in total
Connector for easy expansion!
Up to 7 expansion units can be added

Have you ever had any of these issues when managing energy usage?
● Slow implementation of energy consumption monitoring
and visualization.
● Avoiding the purchase of expensive data loggers
● Having to deal with trakcing and measuring far away
facilities
● Not having a LAN or other system you need in place
Solve it all
with the
KW2G-H!!
Application example
Ideal for switchboards or embedded devices
Through the use of an SD card for storage, energy data can be gathered without the need for an external data
logger or network connection. This allows installation in smaller spaces and in remote locations.

Notes:
1) KW2G-H can measure regeneration electric power. Integrated electrical power is not integrated (not subtracted) when detecting regeneration electric power.
2) While detecting regeneration electric power, minus is displayed on instantaneous active electric power and power factor.
3) Eco-POWER METER is designed chiefly to manage saving energy. It is neither intended nor can it be legally used for billing.
4) Displayed digit of pulse counter differs according to the pre-scale set by pre-scale setting mode.

Notes: 1) Using the setting mode, you can select whether or not to write to the SD memory card for each of file types 1, 2, and 3. Files can be created for each unit.
2) When the battery gets low, the "BATT" display will start flashing. Please replace the battery in accordance with the battery replacing procedure. Also, battery life will be shortened if the main unit is used
in a high temperature environment.
* While measuring, data is collected in the memory of main unit. If, while measuring, the memory capacity of main unit is reached, data will be overwritten in succession starting from the oldest data. Initialization of the main unit memory is possible.
