Systemair ITR1.5A Speed Controller

The electronic speed controllers of the ITR series control the speed of single phase (110-240V AC / 50-60 Hz) voltage controllable motors by varying the supplied voltage. ITR controllers provide automatic power supply detection. The minimum speed is internally adjusted via a trimmer. The output is regulated by a potentiometer in the range of the minimum output votage to the supply voltage. The ITR controller provides an unregulated output for a three-wire motor connection, valve, lamp, damper, etc. There are two start-up modes - kick start and soft start, internally selected by placing or removing a jumper on the PCB. Key Features Wide power supply range (110-240V AC / 50-60 Hz) Automatic supply voltage detection Adjustable stepless output voltage Minimum speed adjustable by internal trimmer Kick start or soft start Illuminated on/off switch
