The Curtis 1520 Series is a family of high-performance, separately excited (SepEx) DC motor speed controllers widely used in electric vehicles. While its core technology is shared with other models like the 1214 or 1268, the 1520 is specifically designed as an OEM controller, meaning it is often fine-tuned at the factory for specific applications. As a result, a dedicated 1520 manual is rarely published to the public, and most technical documentation is integrated into the service manuals of the vehicles it powers, such as Club Car golf carts and utility vehicles.
