operating power depending on the power usage conditions so that you can see where energy can be saved.

Note: This is just an example of setting the threshold values.
KM50 Power Monitors have a thermister chip built onto the panel surface for easy measurement of the panel surface temperature.
The temperature display can be offset to match the room temperature to manage trends.
In addition to the consumed energy (total regenerative power consumption), generated power (total regenerative energy) can also be measured.
A single Power Monitor can measure equipment that effectively uses power generated by reverse motor rotation.
In addition to instantaneous reactive power, the total leading or lagging power consumption can also be measured.
Together with peak power measurements, this function aids with monitoring the power distribution equipment.
Automatic range switching enables high-accuracy measurements even for microcurrents.
Standby and stopped power can be accurately measured.
When measured at the distribution board, the total of the distributed values is almost the same as the base measurement.
You can measure microcurrents of ±75 mA with a CT with a rated current of 100 A. (Reference Value)
You can measure microcurrents of ±4 mA with a CT with a rated current of 5 A. (Reference Value)
Note: Reference values are typical values. Actual values may vary.
Measurements can be made on the primary side of an inverter.
Power consumption can be measured even after installing inverters which are widely used to save energy. This enables you to accurately grasp the effect obtained by introducing the inverter.
The total power consumption can be converted to the equivalent monetary cost.
Energy consumption classified as standby and stopped power can also be converted to the cost.
Displaying the cost of the wasted energy can be used to support energy-saving measures.
Alarms can also be set up for generated power (regenerative power), current, voltage, power factor, or reactive power to assist plant monitoring.
Data can be saved as follows: 5-minute data for two days, 1-hour data for eight days, 1-day data for month, and 1-month data for one year.
Measurement is possible for single-phase two-wire, single-phase three-wire, three-phase three-wire, and three-phase four-wire power.
You can directly measure the voltage of a three-phase, three-wire 400-V line.
Incorrect voltage wiring can be detected.
If any mistakes were made during installation, they are automatically detected, reducing the time required for checking after installation.
This also reduces the risk of having to restart when a mistake is found.
Display for Faulty Wiring
Up to 99 KM50 Power Monitors can be connected using RS-485 Modbus.
The energy use of each device can be managed with minimal wiring.
