PRODUCT DESCRIPTION
The separately excited motor speed controller, Curtis Controller Model 1268-5411, operates at a high frequency of 16 kHz, making them a noiseless and cost-efficient choice as they allow smooth control of brake, torque, and speed. It is designed to suit heavy-duty transport vehicles ranging from high-power demand golf carts to utility vehicles.
The Curtis 1268-5411 is a 36-48-volt model with 400 amperes current limit and utilizes an ITS throttle. The controller weighs 3.9 kg and is 229 mm in length, 178 mm in width, and 81 mm in depth. The design is particularly similar to Curtis 1266 but is more suitable for heavier applications. This controller has regenerative braking and programmable parameters as its key features. It also has well-protected components, cutback functions, mobilization control, and WalkAway feature among others.
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.
