Mellor Brushless DC Motor Controller. DC Motor controller is designed for use with Brushless DC motors with hall-feedback. The controller requires an external 24 V dc and can be installed using screws or standard rail mounting base. It features easy set speed adjustment, direction change and braking. The controller also includes several control modes; internal or external proportional control or external input, 0-10 V or PWM selectable. PWM selectable can set the speed of rotation by an external device. The controller is protected against reversed input voltage polarity and fuse protected against overcurrent. 24 V dc supply voltage Single phase output Direction change Brake system Hall-transducer Adjustable speed limit Direct or frequencies driving High efficiency In-built resettable fuse Rail mounting base available
