PRODUCT DESCRIPTION

The Curtis Controller 1203A-503 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-503 is a 24-volt model with a current limit of 65 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.

The controller can now be purchased here in Cloud Electric, your one-stop shop for all your electric component needs. Cloud Electric is a leading distributor of electronic components in North America. We take pride in our informative product descriptions, pricing, and shipping speed.

FEATURES

The Curtis 1203A model includes cutting-edge characteristics making it an efficient controller for a variety of PMDC motors, including brushless DC electric motors.

Feature	Purpose
Regenerative Brake Control	Allows recovery of energy used for braking. This energy is then stored and used to improve the range of an electric vehicle.
Variable Drive Speed	Allows accurate vehicle control for an improved driving experience
Power MOSFET	Highly efficient, smooth, and noiseless operation
Throttle: Single-ended	Allows full off and full on controls at opposite ends of throttle and a separate component for switch intended for direction control.
Mounting Option: Front or Back	Mountable in either front or back
Dual Ramp Reversing (Automatic)	Allows swift transition in terms of acceleration or deceleration when switching from forward to reverse or vice versa.
Trimpots (On Board)	Allows acceleration and brake adjustment Allows reduction of speed for reverse function
Switch or Potentiometer (External Component)	Allowing adjustment of top speed by programming it externally
Neutral Throttle	When the vehicle is off and unmanned, it brakes motor
Electromagnetic Brake	Slows down the vehicle by creating resistance once the throttle is on neutral.
Easy Installation	No further alterations are necessary and utilize a two-wire potentiometer

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
