AC motor 5 A | variable fan speed control | TK monitoring

The Sentera ITRS9-50-DT fan speed controller, part of the ITRS9 series, efficiently regulates single-phase voltage controllable motors (110—240 VAC / 50—60 Hz) by adjusting the supplied voltage. The adjustable stepless output voltage enables precise fan speed control for optimal performance Offering automatic power supply detection, thermal contacts (TK) for motor protection, and open (NO) and closed (NC) inputs for remote start/stop, the controller ensures versatile and safe operation. Internally adjustable via trimmers, the ITRS9 controllers set minimum and maximum speeds. The series incorporates an unregulated output for devices like valves, lamps, or dampers, regulated by a potentiometer within the range of minimum output voltage to the supply voltage. Equipped with kick-start and soft start modes, selectable via a jumper, the controller provides flexibility in motor acceleration. The ITRS9-50-DT model, with a maximum motor current of 5,0A, features an illuminated on/off switch, LED indications for quick diagnostics, and an alarm output for timely issue alerts. In summary, the ITRS9-50-DT offers precise speed control, safety features, and flexibility, making it an ideal choice for HVAC systems.
