Fan speed controller with day-night function - 7,5 A
This is a transformer fan speed controller with day-night function. Two optimal motor speeds can be selected. The integrated change-over input, makes it possible to select one of these optimal motor speeds. A clock, thermostat or switch can be connected to the change-over input. Single-phase voltage controllable motors with a maximum current of 7,5 A can be controlled. The output voltage with perfect sinusoidal shape, guarantees quiet motor operation. The enclosure allows surface mounting in indoor environments (IP54).
Fan speed control - high-low speed

Manual fan speed control - AC voltage controllable motor
This solution controls single-phase motors. The maximum motor current is 7,5 A. Typically, it regulates fan speed in HVAC applications. Two optimal fan speeds can be selected via the 5-step rotary switches. Via a clock, thermostat or external switch, one of both can be selected.
Temperature control - AC voltage controllable motor
This solution controls single-phase motors. The maximum motor current is 7,5 A. Typically, it regulates AC fan speed in HVAC applications. Two optimal fan speeds can be selected via the 5-step rotary switches. The IMRT thermostat will activate the high speed when the temperature setpoint is exceeded.
