Triac and Phase Cut Motor Controls

Triac controls are used in a wide variety of applications such as pumps, vacuum cleaners, blenders, mixers, fans, lamp dimmers, and other small tools and appliances where variable uni-directional speed control is desired.

They are ideal for universal motors, DC brush motors, AC induction (PSC) motors, shaded pole motors and resistive loads. LCR has developed easily-customized demonstration boards to reduce OEM project start-up time. Contact an LCR representative for information on how to obtain a sample.

All of our triac controls feature:

  • Single, multiple or ranged voltage (85 to 265 VAC)
  • Variable motor speed
  • Operating temperature range of -40 to 85 ºC and beyond
  • RoHS compliance
  • Broad range of load current options
  • Feedback control options
  • Custom user interfaces
  • Current monitor options
  • CE compliant including EMI
  • Customized designs
  • Quick time to market

 

LCR offers the following three standard boards that provide various features depending on your design needs. These products are available off the shelf, or are customizable -- consult for details on how we can help meet your specialized needs with these products or custom design filters.
