Overexcitation Controls

Warner Electric’s Overexcitation (OEX) Controls provide rapid cycling functions – the clutch/brake speed of response can be increased for improved accuracy and performance through overexcitation, which is the application of a short high voltage pulse to provide nearly instantaneous torque.

CBC-700 Series Control
CBC700_control_000General Purpose OEX Control The CBC-700 is a simple, compact, high performance OEX control for either 90 or 24 VDC clutches and brakes. OEX spike duration and anti-overlap time delays are adjustable. It has two optically isolated inputs.

CBC-700
Model No. Input Voltage Output Voltage Part No.
CBC-700-24 24-28 VAC 24 VDC, 105 VDC 6042-448-002
CBC-700-90 120 VAC 90 VDC, 340 VDC 6042-448-003

 

CBC-750 Series Dual Channel

CBC750_control_000Dual Channel, Current Based OEX with Switching Logic Warner Electric’s CBC-750 Series of Constant Current Overexcitation Clutch/Brake Controls are solid-state electronic controls designed to increase the cycle rate capabilities and accuracies of electromagnetic clutches and brakes. By using overexcitation, the response time is reduced as dramatically as performance is increased. For example, the current build up time of a 5 inch, 6 volt magnet is reduced from 84 milliseconds to 2 milliseconds.

The CBC-750 user selects either 120, 220 or 240 VAC operation at the time of installation. Models for 6 volt, 24 volt, or 90 volt clutches and brakes are available.

Unit shown with optional cover, part number 6041-101-004.
