The controller P124M-5305 provides an economic DC series winding motor speed controlling solution.

Made by a Chinese manufacturer, P124M-5305 is the replacement of CURTIS 1204M-5305 (36-48V / 325A)and CURTIS 1204M-5203 (36-48V / 275A), with the same functions and dimensions.

If you need to modify any controller parameter, please send us a message with the list of parameters to be modified.

We supply also the P124M-5305 controller assemblage with throttle (foot pedal), please contact us for more details on price and delivery delay.

Overview:

P124M-5305 programmable series motor controllers are designed to provide smooth, silent, cost-effective control of motor speed and torque. P124M-5305 controllers are fully compatible with 1204M-5203 and1204M-5305, the updated version of the popular 1204 / 1204M controllers, with the added functionality of being programmable-via the CURTIS Model 1313-4431 Handheld Programmer or 1314 PC Programming Station. This means the controllers can be tailored to the needs of specific applications. In addition to configuration flexibility, use of the programmer offers diagnostic and test capability.

P124M-5305 controllers are the ideal solution for a variety of electric vehicle applications, including industrial trucks, personnel carriers, material handing vehicles, golf cars, etc.

Wiring Diagram:

By default, the J5 terminal of controller P124M-5305 is not activated. The controller wiring is same to the old 1205M controllers without J5 terminal.
