The MultiMode motor speed controller, Curtis 1244-6561, is used for separately excited (SepEx) motors. This controller is cost-efficient, only requires simple installation, and operates silently when utilized in controlling the speed, brake, and torque of the motor. This controller can also be used with CAN Bus communication systems. In the industry, controllers under Curtis 1244 can be applied to vehicles used for material handling with order pickers and counterbalance trucks as an example.
The Curtis 1244-6561 is a 48/84 volt model with 500 amperes and utilizes a 5K-0 ohms throttle input. The controller weighs 3.9 kg and is 229 mm in length, 178 mm in width, and 81 mm in depth. It provides a better driving experience due to embedded and optional features, which can be added according to preference and application demand.
The controller can now be purchased here in Cloud Electric, your one-stop shop for all your electric component needs. Cloud Electric is a leading distributor of electronic components in North America. We take pride in our informative product descriptions, pricing, and shipping speed.
