Starting with 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 means fewer natural resources are consumed.

Reduction of power consumption: 33kWh/year
CO2 emssions: 15 kg/year, approximately 66% reduction


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 fan.

The Effects of Using a Thermostat
-Application Example-
-Volume setting (operating temperature of thermostat): 40°C
-Cooling fan: MU1428S-11 × 1
(140 mm-28 mm thick cooling fan)
-Size of control cabinet: W:470×H:470×D:160 mm
-Heat generated by heat source: 200 W

EC Fans EMU Series

EC Fans
EMU Series



Reduced power consumption through the use of a built-in brushless motor. With support for a wide voltage range, the fans can use single-phase 100-240 VAC (50/60 Hz).
The same characteristics can be achieved regardless of the frequency used.

EC Fans EMU Series

Fan Thermostat
AM2-XA1



Automatically controls the operation of the fan in accordance with temperature fluctuations inside the equipment. This helps improve the equipment's "environmental" performance relative to energy savings, noise reduction, etc.
