Curtis 24V 78A (WW) PM Controller 1203A-518S
The Curtis Controller 1203A-518S is a 1203A model designed to cater motor speed control for numerous mid-ranges to heavy-duty industrial applications ranging from small vehicle controls to power steering and much more. It is a controller that can efficiently be used for high-performing permanent magnet (PM) motors and it only requires a few external components to build a full-functioning control system.
The Curtis 1203A-518S is a 24-volt model with a current limit of 78 amperes and utilizes a center-off throttle. The controller weighs 0.28 kg and is 152 mm in length, 127 mm in width, and 31.75 mm in depth. It provides a better driving experience due to embedded features and optional features offered, which can be added according to the preference and demands of the desired application.

Features for Safety and Protection
It is extremely critical to have the necessary safety functionalities to protect the PMDC motor and its controller. The Curtis 1203A model comes with numerous protection features that make it highly reliable:
Fault Detection Potentiometer: Helps in avoiding runaway conditions
Housing/Heatsink: A protective feature against heat
Current Limit: This feature is helpful for compatibility of the controller with most motors as it prevents over currents for both components
Polarity Protection: Protects the controller by remaining off when the battery wire is reversed due to installation
High Pedal Disable (HPD): Allows a safe start as it monitors the status of the throttle. If the vehicle is prompted to start with an applied throttle, the HPD disables the operation until the throttle is back in a neutral position
Temperature Protection: Limits the current of an overheated controller and resets it after cooling down.
Cutback Function (Undervoltage): Allows low battery operation by reducing motor current once the battery is approaching ⅔ of its nominal voltage and prevents the battery from discharging beyond the ⅔ voltage limit
