Auto Transformer fan speed controllers ATC & ATC-TK range
A range of auto transformer fan speed controllers for use with single and three phase voltage controllable fans. Auto transformer speed controllers regulate the voltage output whilst maintaining a true sine wave. The great advantage of this type of control is the low motor noise (humming) and almost no EMC emission problems
The ATC-TK range has connections for a fan motors thermal contacts (TK’s). If the motor overheats and the contacts open then the controller will trip and the fan will stop. This range of controllers can also be used on fans without thermal contacts by simply fitting a link in the controllers.
ATC1-1.5TB
The ATC1-1.5TB has the option of connecting a switch device e.g thermostat to terminals 1 & 2. When the switching device operates the fan will change from trickle speed (as set of rotary switch) to full speed.
