SM263 MOTOR CONTROLLER
Introduction
The SM263 is a compact, general purpose DC motor controller. It is available in 12V and 24V versions, with a steady output of up to 80 Amps. It has a range of features to suit different situations that may be selected by the installer.
Standard features include:

Standard features include:
- LOW BATTERY WARNING
- DAMPENED ACCELERATION
- ON-BOARD FORWARD / REVERSE / BRAKE CONTROL
- STALL & OVER CURRENT PROTECTION
- SIMPLE 2-WIRE CIRCUIT MANAGES POWER ON/OFF, SPEED & DIRECTION
- SUPPORTS REDUCED SPEED IN REVERSE
- SUPPORTS SELF-TEST & SAFETY CHECKS UPON POWER UP
- SUPPORTS DYNAMIC (RESISTIVE LOAD) BRAKING

An optional backlit Liquid Crystal Display (SM267) can be fitted to give the operator information on battery condition, drive status and system integrity
Protection Features
Four levels of protection from stalled motor events. Should a full locked-rotor stall occur, a rapid beep will warn the operator that a brief power reduction down to 30% drive will occur if they persist. Additional safety software monitors the integrity of the power semiconductors when the throttle is at rest. The software which will automatically isolate the motors should any drive fault conditions be detected, making it a very safe controller to use.
When first activated, the throttle must be at-rest in the Forward direction, or warning beeps will sound and the controller is disabled until this is done. This safety feature guards against the possibility of a runaway vehicle if the throttle was rotated before battery power was first applied.
Direction Control Motor rotation activity is monitored by the microprocessor to prevent the user going into hard reverse while still moving or rolling forwards. This protects both the user from experiencing sudden changes in acceleration and protects a gearbox and drive components from mechanical stress damage.
Simple Connections
The controller supports one or two 12V motors, or one 24V motor. Throttle Potentiometer, Key switch, Forward/Reverse switch all connect via a single wire loop circuit. The display connects via a common RJ12 (telephone style) patch cable.
