Fan speed controller 400 VAC - TK monitoring - remote run-stop - 1,5 A

Fan speed controller 400 VAC - TK monitoring - remote run-stop - 1,5 A

Product description

This is a transformer fan speed controller with digital input, alarm output and unregulated output. It controls three-phase voltage controllable motors with a maximum current of 1,5 A. The fan speed is regulated in 5 steps by varying the motor voltage. The TK monitoring function deactivates the motor in case of overheating. The digital input can be used for remote start-stop commands. After a power failure, the motor will automatically restart. The output voltage with perfect sinusoidal shape, guarantees quiet motor operation. The enclosure allows surface mounting in indoor environments (IP54). Available voltage taps: 0-130-180-230-300-400 VAC

Additional specifications and description

How does it work?
One of the five available speeds can be selected via the rotary switch. At position 0, the motor is disabled. Position 1 is low speed and position 5 is high speed.

Remote start-stop
Via the input(s), the motor can be remotely enabled or disabled. There is a normally open input and a normally closed input available.
E.g. via a remote switch - connected to the normally open input - the motor is enabled or disabled. A smoke alarm can be connected to the normally closed input. If a smoke alarm occurs, the motor will be disabled - regardless the status of the other input.
Unregulated output
The extra, unregulated output (230 VAC) is active when the motor is enabled. It can be used to control an external run-indicator, a damper, etc.
E.g. when the fan is deactivated, the dampers is closed. When the fan is active, the damper is open.

Thermal motor protection
This fan speed controller can monitor thermal motor contacts (TK or thermal contacts measure temperature in the motor windings). In case of motor overheating, the TK monitoring function will disable the motor to prevent motor damage. If the motor is not equipped with TK contacts, both TK terminals of the controller must be bridged to simulate normal motor temperature.

Alarm output
The alarm output (230 VAC) is activated when motor problems occur. It can be used to generate alerts.
E.g. in case of motor overheating, the alarm output is activated. The TK monitoring function will disable the motor to prevent further damage. The alarm output can control a warning light.

Auto reset after power failure
In case of a power failure, this controller will automatically reset itself. When the power is restored, the motor will restart automatically.

Solid enclosure
The enclosure is made of high-quality steel. The enclosure can be surface mounted and offers an IP54 protection against ingress of dirt, dust and moisture.
