Easy Air Flow Control

The air flow can be easily adjusted by simply turning the setting dial.
Also, the air flow of the fan can be checked on the controller’s display.

Realizes Noise Reduction and Reduces On-Site Stress

Realize noise reduction by setting the fan to low speed.
Allows you to reduce equipment noise even after equipment is installed.

Energy Savings Reduces Running Costs

Achieves a reduction in wasted power by driving the fan at the required air flow when needed.
Realizes energy savings and contributes to reduced running costs.

Range of Use Expanded by 2 Speed Control

By using an external input signal, can be set to any speed with the setting dial, and 2-speed switching with full speed is possible.
Also, when combined with a thermostat (sold separately), 2-speed switching can be automated (switching is triggered by ambient temperature).
Using this function, it is possible to optimize the air flow according to the load and operation conditions (for further noise reduction and energy savings).

Introduction to Examples of Utilization

Adjust the air flow according to the type of load (Size/Density)

When a fan that adjusts the air flow according to the type of load (size/density) is used to cool the load, it can be connected to an external input such as a sensor to switch the speed, such as full speed (strong wind) for large loads, or low speed (weak wind) for small loads.

Adjust the air flow according to the ambient temperature

When the fan is used for temperature control in a control cabinet, it can be connected to a temperature sensor such as a thermostat instead of a 2-speed switch, and the speed can be switched between full speed when the heat generated in the cabinet is high and low speed when the temperature is normal.

Early Detection of Abnormalities, Full Range of Alarm Functions

Outputs an alarm signal when there is an abnormality in the fan or controller. This contributes to the reliability of the equipment.
In addition, alarm contents being generated can be identified on the display of the controller. (External output by alarm signal output is also possible.)

Can Control the Air Flow of Multiple Fans Simultaneously

This is a single speed controller that can control multiple fans at the same air flow.
(Up to 8 multi-fan operation units can be connected, depending on the connection.)

Compact Shape and Choice of Easy Mounting Methods

This is a lightweight (65 g) compact speed controller.
Three mounting methods can be selected according to installation conditions: “panel mounting,” “DIN rail mounting,” and “screw mounting.”
