Energy Saving, Noise Reduction Operation During Fan Drive

Fan power consumption can be reduced by operating the fan only when necessary.
It also minimizes the noise emitted by the fan.

Application Example

ON-OFF Control for a Single Cooling Fan

When the inside of the equipment gets hot and reaches the setting temperature, the cooling fans are driven automatically, and it has cooled down, they automatically stop.

ON-OFF Control for Multiple Cooling Fans

For example, the AC Axial Flow Fan MU Series can drive up to 9 units at once. When the air flow of a single unit is not enough, multiple units can be controlled by a single thermostat.

Usage Example: 6 MU1238 type units

Operation Unit Number Switching Control

Two AM2-XA1 thermostat for fan can be used to switch operations for multiple fans. This allows the air flow to be changed between high and low temperatures, contributing to energy conservation and noise reduction.

Example

Three MU1238 type AC axial flow fans each with high temperature (40 °C) and low temperature (25 °C) settings

Power consumption halved/Noise reduced by 3 dB

100 V 50 Hz
