Curtis Model 1505 Speed Controller

Curtis Model 1505 Pulse Width Modulation 24 Volt DC Motor Speed Controller

The Curtis PMC model 1505 is a small, simple, low cost, unidirectional controller designed for electric bicycles, scooters, mopeds, trolling motors, pumps, and other small PM motor applications. It offers smooth, silent cost effective control of motor speed and torque. It has no annoying delay on acceleration like most stock scooter and bike speed controllers have. These controllers have strong electronic dynamic brakes as you let off of the accelerator, eliminating the need for a mechanical rear brake usually. 24 Volt dc, 20 Amps continuous duty, 80 Amps for 1 minute rating. Thermal overload protection rolls current back when unit gets hot to protect the electronics. Common 5k Ohm potentiometer throttle input.

• Power MOSFET design provides silent high frequency, high efficiency operation which reduces controller heating, motor and battery losses.

• Current limited to protect the electronics.

• 3 wire 5k Ohm potentiometer throttle input.

• Open wire pot fault feature turns off controller if any throttle wire becomes open circuit.

• Under voltage cutback reduces output current as battery voltage drops below a preset level.

• Keyswitch input to turn on the controller.

• Simple installation with no adjustments required.

• Quick connect terminals.

• Sturdy black plastic protective case available for protection of the circuit board.
