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.
