UM Series Smooth-Start UniModules Warner Electric Smooth-Start™ UniModules are designed for applications that require a softer than standard engagement. Through the use of LK friction material, the Smooth-Start design provides reduced torque to provide a less aggressive engagement, without suffering a loss of overall life due to the longer slip times. When used with an adjustable power supply such as the CBC 300 or CBC 500/550, the SmoothStart designs can provide a soft engagement that can be adjusted to meet specific application needs. Smooth-Start™ UniModules Warner Electric’s new Smooth-Start UniModules are offered in 90 volt configurations as listed below. If you require another voltage, size or mounting configuration, please contact Warner Electric for assistance. UniModule Size NEMA Frame Static Torque (lb-ft) Original Part Number CBC-300 Dual Channel Torque Adjust Clutch/Brake Control Part Number Input Power Pulse-width modulated full wave rectified D.C. Constant current, switch selectable ranges, 0-90 volt. Current Adjust Dual adjustable channels. Adjust via front panel potentiometers. Other Features Conveyor applications occasionally require more clutch torque to start the line, and less brake torque to stop the line. With two independently adjustable channels, Warner Electric’s CBC-300 allows you to set the torque levels for the clutch and brake independently of each other, so each can be tailored to every application to achieve optimum system performance. UL listed; short circuit protection, line to line; torque limiting protects machine components from damage.
