Starting with the Control Cabinets
Reduced Power Consumption with an EC Fan
Cooling fans offer adequate ventilation and air flow for the forced-air cooling of control cabinet heat sources. The EMU Series of EC fan achieves reduced power consumption through the use of a built-in brushless motor. With a long expected life of 60,000 hours, approximately 2.2 times longer than the conventional product, this also contributes to resource conservation.

Use of a Thermostat to Cool Only When Necessary
By combining the cooling fan that is already in the control cabinet with a thermostat, cooling becomes more efficient.
This will stop the cooling fan when the enclosure is already cool, reducing the power consumption from the cooling fan.

Compatible Products
EC Fans
EMU Series
Reduced power consumption through the use of a built-in brushless motor. With support for a wide voltage range, can use single-phase 100-240 VAC (50/60 Hz).
The same characteristics can be achieved regardless of the frequency used.
Thermostat for Fan
AM2-XA1
Automatically performs ON and OFF fan control in accordance with the temperature fluctuation inside the equipment. This helps improve the equipment's "environmental" performance relative to energy savings, noise reduction, etc.
