Speed controller for single phase voltage controllable motors.

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 startup
modes – kick start and soft start, internally selected by placing or
removing a jumper on the PCB.
