1. INTRODUCTION
Thank you for purchasing the BC140™ / BC140-FBR, full-wave variable speed DC motor controls. Baldor
is committed to providing total customer satisfaction by producing quality products that are easy to install
and operate. The BC140 and BC140-FBR offer the user the ultimate in reliability and performance at an
affordable price.
The BC140 and BC140-FBR represent the latest in state-of-the-art design, surface mount technology,
incorporating advanced circuitry and technology for variable speed DC motor controls. They are rugged and
compact in size and are able to handle both 115 and 208/230 Volt AC line inputs by setting the built-in Dual
Voltage Switch. In addition, one model can be used on a wide range of motors by selecting and inserting the
appropriate Plug-in Horsepower Resistor

.
The standard model, BC140, controls all motors through 3/4 HP at 115 Volt AC line input and 1-1/2 HP
at 230 Volt AC line input. By installing the Auxiliary Heat Sink (see Table 1-2), the horsepower range is
increased to 1 HP at 115 Volt AC line input and 2 HP at 230 Volt AC line input. The versatility of the control is
enhanced with the optional Forward-Brake-Reverse Switch Kit (Catalog No. BC144)

*Note:
Forward-Brake-Reverse Switch Kit, BC144, is factory installed on the BC140-FBR model.
The electronics for the BC140 and BC140-FBR consist of a patented speed control module. Its field-proven
reliability is confirmed by over 100,000 controls presently in operation. The module is housed in a rugged
metal enclosure not plastic. Keyhole slots facilitate mounting and an easily accessible terminal block
simplifies connections.
