Belimo CMB24-SR-L Damper Actuator 24V 18In-Lb

Description:

Simple direct mounting on the damper spindle with a universal spindle clamp or form fit, supplied with an anti-rotation bracket to prevent the actuator from rotating. Manual operation is possible with a magnet (the gearing latch remains disengaged as long as the magnet is in place). Adjustable angle of rotation with mechanical end stops, that requires no tools to move or remove. The actuator is overload-proof, requires no limit switches and automatically stops when the end stops is reached. The CMB24-SR (-R or -L) actuator uses a brushless DC motor, which is controlled by an Application Specific Integrated Circuit (ASIC). The ASIC monitors and controls the actuator’s rotation sensing (DRS) function to prevent damage to the actuator in a stall condition. Power consumption is reduced in holding mode. Belimo’s Halomo sensorless brushless DC motor spins by reversing the poles of stationary electromagnets housed inside rotational permanent magnets. The electromagnetic poles are switched by the an ASIC developed by Belimo. Unlike the conventional DC motor, there are no brushes to wear or commutators to foul. This means the brushless DC motor adds accuracy and reduces power consumption in a holding mode.
