CaptiveAire KBWC-110K User Manual

DESCRIPTION

T

he KBWC Series is a comprehensive line of motor speed controls
for air-moving applications that utilize Shaded Pole, Permanent Split
Capacitor (PSC), and AC/DC motors. These economical speed controls
are designed to replace obsolete, tapped winding, or reactive methods
of speed control. The full-wave phase control circuitry minimizes power
loss, thereby reducing energy requirements. The controls provide infi­nitely variable speed adjustment which allows the end-user to select the
desired level of air volume. These models cover a wide range of current
ratings (2.5 - 15 Amps AC) and voltage ratings (115, 230, 277 Volts AC).

Important features, such as RFI Filter, Minimum Speed Trimpot,
and built-in On/Off Line Switch are standard. These speed controls are
available as bulk packaged or in distributor type packaging with acces­sories such as: knob, dial plate, mounting hardware, instructions, and
individual carton. All models are designed to be mounted into a stan­dard 2” X 4” electrical wall box.

APPLICATION NOTES

1. Radio Frequency Interference (RFI): All solid-state speed controls generate annoying radio noise on the AM band. KB speed

controls contain, as standard, a high-gain RFI suppression filter which significantly reduces this interference.

2. Low End Set Point (Minimum speed): All 115 Volt input speed controls are factory set to 60 Volts AC output (±3 Volts), as

standard. All 230 Volt input speed controls are factory set to 120 Volts AC output (±6 Volts), as standard. All controls are factory

calibrated using an average responding AC voltmeter. Custom voltage settings are available.

3. Motor Suitability: Motors must be loaded to near full capacity with the appropriate fan blade in order to achieve proper speed

control. Generally, motor suitability is established by determining motor speed as a function of applied voltage. A motor is

determined as suitable if it changes speed linearly over a wide range of voltage.

It is required that all motors contain a built-in thermal overload protector when used with solid-state speed controls.

4. 230 & 277 VAC Controls: To achieve maximum reliability, all 230 VAC controls contain snubber networks that utilize Y-Type

capacitors and flame-proof resistors. In addition, all 277 VAC controls contain MOV Transient Suppression.

5. Temperature Test: The non-sinusoidal output voltage of a solid-state speed control may increase motor heating. Therefore, it is

necessary that a temperature test be performed to ensure that the motor is operating within manufacturer’s specifications.

6. Leads: All leads are approximately 6” (15 cm) long and stripped 1/2” (1.25 cm). Custom lead lengths, colors, and terminations

also available.
