This is a variable speed controller. It regulates fan speed from high to low. Designed for single-phase voltage controllable motors with a maximum current of 2,5 A. The minimum speed can be adjusted via an internal trimmer. The enclosure allows inset mounting (IP44) or surface mounting (IP54). Phase angle control (Triac technology) is used to vary the motor voltage and to regulate the motor speed.
Via the rotary knob, fan speed can be set
from high to low
by turning the knob clockwise. This knob has an OFF-position. Turning
the knob counter-clockwise stops the
enclosure, different mounting possibilities
The enclosure is made of
is UV resistant, it protects against impacts and looks nice. It
protects the electronics against ingress of dust, dirt and water. The
protection class is IP44 for inset mounting and IP54 for surface
unregulated output (230 VAC) is active when the
motor is enabled. It can
be used to control an external run-indicator, a damper,
when the fan is deactivated, the damper is closed. When the fan is active, the
damper is open.
