KB Electronics Fan Speed Control
The KB Electronics KBWC are wall mount fan speed controllers. These innovative controls are designed to seamlessly fit into a 2" X 4" electrical wall box, offering convenience and ease of installation. Operating flawlessly on 115/230/277 VAC, 50/60 Hz, these controls have a remarkable maximum rating ranging from 2.5 - 15 Amps, ensuring optimal performance in ambient temperatures ranging from 25° to 40ºC.
Experience the power of infinitely variable speed motor control, perfectly suited for Shaded Pole, Permanent Split Capacitor, and Universal (AC/DC) motors. The variable speed motor control boasts an array of impressive features, including an on/off line switch for effortless operation, a high gain RFI noise suppression filter for a whisper-quiet experience, an adjustable trimpot that allows you to set the minimum speed to your desired level, and a flame-retardant ABS enclosure that prioritizes safety.
Versatility is at the core of the KB Electronics KBWC, with applications extending to Ceiling Fans, Commercial Vent Hoods, Industrial Blowers, Laminar Flow Hoods, Heat Tunnels, and Magnetic Stirrers. Don't miss the opportunity to enhance your motor control experience with KB's 21 Wall Mount, AC Motor Fan Speed Controls.
- Radio Frequency Interference (RFI): Solid-state speed controls are notorious for producing irritating radio noise on the AM band. However, our KB speed controls come equipped with a high-gain RFI suppression filter as a standard feature, effectively minimizing this interference and providing a more enjoyable listening experience.
- Low End Set Point (Minimum speed): KB Electronics’ speed controls are designed to meet the specific voltage requirements of your system. For 115 Volt input controls, the factory settings ensure a consistent 65 Volts AC output (with a variation of ±3 Volts) as the standard. Similarly, for 230 Volt input controls, the output is set to a reliable 120 Volts AC (with a variation of ±6 Volts). Rest assured, all our controls are meticulously calibrated using a responsive AC voltmeter. If you have unique voltage needs, we also offer customizable settings to cater to your specific requirements.
- Motor Suitability: Achieving optimal speed control for your motor requires careful consideration. Proper loading of the motor, combined with the appropriate fan blade, is essential. Motors are tested for suitability by determining their speed response to applied voltage. A motor is deemed suitable if it exhibits a linear speed change across a wide range of voltages. Also, to ensure the safety and longevity of your motor, it must include a built-in thermal overload protector when used with our solid-state speed controls.
- 230 & 277 VAC Controls: KB Electronics prioritizes reliability, especially when it comes to the 230 VAC controls. That's why all the 230 VAC controls are equipped with snubber networks that utilize Y-Type capacitors and flame-proof resistors. This ensures maximum performance and protection. Furthermore, our 277 VAC controls feature MOV Transient Suppression, further enhancing their reliability and durability.
- Temperature Test: It's essential to consider the impact of a solid-state speed control's non-sinusoidal output voltage on motor heating. To guarantee that your motor operates within the manufacturer's specifications, KB Electronics has conducted rigorous temperature tests. This ensures that your motor remains in optimal condition and delivers consistent performance.
- Leads: We understand that every project has unique requirements. Conveniently, this model leads come in a standard length of approximately 6" (15 cm), stripped 1/2" (1.25 cm). However, if you need custom lead lengths, colors, or terminations, we offer a range of options to suit your specific needs and preferences.
What is an AC Fan Speed Controller?
AC Fan motors have two TRAICs (triode for alternating current) to meet variable speed requirements. These thyristors have three-terminal electronic components that conduct current in either direction when triggered. The TRIACs control the voltage of the motor.
eMotors Direct’s stock of AC motor fan speed controllers are designed to control the speed of AC fan motors easily. They provide infinite and precise variable speed control to permanent split capacitor motors, shaded pole motors, and universal motors, so you can run them in low, medium, and high-speed ranges. Most often applied to ceiling fans, commercial vent hoods, industrial blowers, and magnetic stirrers. They are found in the agricultural industry, controlling the speed of barn fans to help provide a more comfortable environment and necessary airflow/exchange.
Our AC motor fan speed controller category covers the wall-mounted fan speed controllers by KB Electronics. Designed to be mounted into a 2” x 4” electrical wall box, these controllers are easy to install and use. They are equipped with an on/off switch, a noise suppression filter, and a flame-retardant enclosure.
