Total Regenerated Energy
The generated power
(regenerative power) is measured, recorded in memory, and displayed.
Power can be generated by utilizing the weight of objects in motion, such as
large cranes or large presses. This regenerated energy can be collected and
stored as an energy saving measure. KM50 Power Monitors display both the power
consumption and power generation, and save these values in the built-in memory.
Therefore it is possible to check the status of the energy generation and total
regenerated energy, as well as the regenerated energy for the last two days in
five minute intervals.
Total Reactive Power
The total reactive
power is displayed and the power factor is improved to support energy-saving
Reactive power is generated when there is a phase difference between the voltage
and the current in the load. If the total reactive power is known, a phase
advance capacitor can be introduced to reduce power loss. This will reduce
KM50 Power Monitors display the reactive power and save the data in the built-in
memory. Therefore it is possible to check the total reactive power for the
advanced or lagging reactive power, as well as the reactive power for the last
two days in five minute intervals.
Conversion to Monetary Cost
The amount of power
consumed in standby mode can be displayed as a monetary cost or the equivalent
It is essential that people in the workplace as well as all department personnel
are committed to energy-saving activities. Presenting the outcomes of the
energy-saving activities with easily understandable information such as the cost
of electricity and amount of CO2 emission can increase the effectiveness of
these activities. The KM50-E Power Monitors can display the power consumed in
different energy classifications in monetary terms.
Flow Rate Measurements
The flow rate and
power can be measured simultaneously, enabling the optimization of energy usage
Pulse inputs from a flow meter with pulse transmission are counted using the
pulse conversion function. Power and the flow rate can be measured
simultaneously, enabling optimized energy usage according to the status of
Simple Temperature Measurements
The indoor temperature
and power can both be viewed, making it easier to manage the energy usage.
With a temperature sensor built into the front panel of the KM50 Power Monitor,
temperature and power can be measured and displayed at the same time. Mounting
the KM50 Power Monitor on the distribution board makes it possible to monitor
the room temperature and status of air-conditioning to devise energy saving
strategies. Mounting it on the control panel makes it possible to monitor the
temperature inside the control panel.
In addition to active
power, the current, voltage, power factor, reactive power, and regenerative
power can be used to monitor the equipment.
Upper and lower limit thresholds can be set for each measurement item. An alarm
will sound if the current, voltage, or power factor instantaneously exceeds the
threshold value. An alarm can also be output when regenerative power
(generation) is generated.
Energy Level Classifications
(Equipment Operation Status Measurement)
Stopped Power (Three-state Energy Classification)
Saving power starts with eliminating standby power and stopped power. The KM50
accurately finds where power can be saved through high-precision measurements,
even for stopped power. The three-state function of KM50-E Power Monitors
classifies power consumption into stopped power, standby power, and operating
power to clarify areas for improvement.
New! In addition to the conventional threshold values,
external inputs can be used to classify the energy level.
of Standby Power When Equipment Is Stopped
Micropower measurement is the key to measuring stopped power. The low-cut
current below the 10% level can be accurately measured. This was not possible
with the measurement accuracy of previous power monitors.
Just Clamp on the
Sensors to Take Measurement
The Power Monitor can be attached without having to stop the power supply
because measurements can be taken directly from the AC input without any wiring.
Data Logging for
Installation Tests and Daily Operation
Measurements are logged at an interval of 5 minutes, 1 day, or 1 month, and
saved in the Power Sensor. The logged data can be analyzed according to the
application to assist in effective operation from installation to maintenance.
Incorrect Voltage Wiring Detection
Incorrect voltage input wiring is detected. The location where the wiring is
incorrect is reported.
The Smart Power Monitor itself can also save energy. The display is turned OFF
whenever there is no key operation.
