The KM1 platform solves the work and cost issues to visualize
Previous Problems
For mixed distribution panels that
contain both power and lighting
circuits, a separate power sensor
was required for each circuit.
Electrical
room
Previously, measuring electric power for multiple circuits or systems required
costly and difficult-to-install power sensors.
Inside power distribution facility
Multiple sensors were
required because each
circuit required its own
sensor.

Monitoring
Industry-first Dual System
Monitoring
A single KM1 can perform measurements for
mixed distribution panels with circuits for both
air-conditioners and lighting equipment.

room
Measure up to
36 circuits.
Add CT Expansion Units for
More Measurements
One Measurement Master Unit accepts up
to 4 CT inputs, and a CT Expansion Unit
accepts up to 8 CT inputs. (Up to four CT
Expansion Units can be added.) This
enables the measurement of up to 36
single-phase two-wire circuits.
Space-efficient Design and Reduced Wiring
Mounting Space Reduced to
1/4 That of Previous Models
With the KM1, all you need is five Power Monitors.
You can reduce the mounting space by 76%.

Visualization of Specific Power
Consumption through
Pulse/Temperature Input Units
Use pulse inputs to measure production information at
the same time, including flow rates, throughput,
temperature inputs, and more. When this information is
combined with other electric power data, you can
easily visualize the specific power consumption.

Primary-side Inverter Support
The KM1 can provide accurate measurements
without any current waveform distortion even after
an inverter is installed. Measurement accuracy:
±2% FS This enables measuring the effectiveness
of energy conservation measures after installation.

The total power consumption and total time can
be divided up between the three states of
stopped, standby, and operating based on the
power consumption value and pulse input.
Classifying energy helps to clearly identify areas
where improvement is possible.
