BC141

The Baldor Electric Company BC141 is an adjustable speed DC drive utilizing SCR control. It is rated for a 115VAC input and provides a 90VDC output with a maximum current of 16.0A. This drive is designed to control motors between 1/100-0.75HP, with the capability to handle up to 1.5HP when an auxiliary heatsink is used. The speed range ratio is 50:1, making it suitable for applications requiring precise variable speed and constant torque.

Key features include full-wave SCR control with a free-wheeling diode, a field power supply compatible with both shunt wound and permanent magnet DC motors, and adjustable parameters for acceleration, deceleration, current limit, IR compensation, minimum, and maximum speed. It also incorporates an adjustable current limit with an indicating LED, a 5K speed pot for control, an anti-demagnetization circuit to protect PM motors and the SCR power bridge, and a noise rejection circuit to prevent false starts. The drive is UL and cUL recognized.

Applications for the BC141 include conveyors, mixers, and packaging machinery, where variable speed and constant torque are essential. The unit has dimensions of 4.30" x 3.60" x 1.30" and weighs 2 lbs. An optional heatsink can be added for enhanced performance.
