Triac Controls
A TRIAC, or triode for alternating current, is a three terminal electronic switch that conducts current in two directions. Because they can switch current in both directions, they are useful for switching alternating current and controlling the average current that flows into a load. This allows triac control components to control the speed of motors, dim lamps, and adjust electric heaters.

Triacs are similar to thyristors in that they are used as solid state switching devices, but with the added benefit of being able to trigger with both positive and negative voltages applied to the anode. This allows for full-wave power control without additional components or complex wiring.

Bidirectional switching makes triac controls ideal for basic AC switching to start/stop a motor or turn on/off a lamp. They are also capable of phase control and can vary the amount of power supplied to a load, useful for motor speed control applications.

KBWC Series Image
  • RFI Filter
  • Minimum Speed Trimpot
  • Built-In On/Off AC Line Switch
The KBWC series is a comprehensive line of motor speed controls for air-moving applications that utilize shaded pole, permanent split capacitor (PSC), and AC motors. These economical speed controls are designed to replace obsolete, tapped winding, or reactive methods of speed control. This model covers a wide range of current and voltage ratings.
  • Various Agent Approvals
  • Standard 2 x 4 Electrical Wall Box
KBMC Series Image
  • Input: 120/240 VAC, 50/60 Hz
  • 1.6-4.0 A Ratings
  • Flame Retardant ABS Enclosure
  • Wall Box Mounting Kit
  • Minimum Speed Trimpot
The KBMC and KBMS solid state controls provide infinitely variable speed control of shaded pole, PSC, and AC/DC motors. The consumer is allowed selection of air volume, noise level, and energy consumption to individual preference. All models utilize full-wave phase control circuitry that minimizes power loss and heat dissipation. Controls are UL recognized and CSA certified.
KBGE Series Image
  • Input 120/240 VAC, 50/60 Hz
  • 15 or 25A Triac Current Rating
  • RFI Supression
  • Electrically Isolated Heat Sink
  • Adjustable Minimum Voltage Trim
The KBGE series solid state triac voltage control assemblies provide the user versatility when used in power control applications. Their convenient, compact size is only 3 x 2 x 1 allowing for mounting in most locations. They are designed to provide a phase controlled symmetrical AC output for variable voltage control or static switching. Applications include air curtains, ventilators, heat tunnels, stirrers, theater lighting, and laminar flow hoods.
