Curtis 1520 Controller Manual <2026 Release>

Ensure the battery is fully charged and within the rated range.

| Parameter | Value / Detail | |-----------|----------------| | | 0–5kΩ pot (standard) or 0–5V (requires programming) | | Main contactor | 150A continuous minimum (Albright SW200 or similar) | | Undervoltage cutback | ~31V (36V system) / 42V (48V system) | | Overvoltage cutoff | ~60V | | Thermal protection | Reduces current if heatsink > 85°C | | Fusing | Recommended 300A–400A class T or ANL |

The Curtis 1520 is a high-performance DC motor controller that features a compact and rugged design. It is capable of controlling motors with currents up to 150A and voltages up to 24V. The controller includes a range of features, such as:

Compatible with 5kΩ 3-wire potentiometers, 0–5V throttles, and ITS (Inductive Throttle Sensor). curtis 1520 controller manual

If your vehicle isn't moving, check these common failure points:

(if applicable)

When installing or troubleshooting, the 24-pin connector is the critical interface. Manuals show the main wiring as follows for its Club Car applications: Ensure the battery is fully charged and within

offers advanced speed control through its microprocessor-based MOSFET design. 48V nominal (can also support 36V).

Controls how fast the vehicle speeds up or slows down when the throttle is applied or released.

Independent control of the armature and field windings allows for precise torque management and smooth direction changes without heavy mechanical contactors. The controller includes a range of features, such

Receives 24V/36V power from the ignition switch to wake up the logic board.

Three wires dedicated to translating the accelerator pedal position into a voltage signal.

While the 1520 is famous for powering Club Car DS and Precedent models, its reliability has made it a favorite for custom projects.

The Curtis 1520 can be programmed using a Curtis 1313 handheld programmer or the 1314 PC programming software. Key Adjustable Parameters
