1237-4104 (164804104) Permanent Magnet Motor Speed Controller Voltage Rating: 48 V Current Limit: 100 Amps Current Rating 1 Minute: 100 Amps Current Rating 1 Hour: 40 Amps Curtis PMC Model 1237 is an advanced, programmable microprocessor based motor speed controller which offers smooth, silent, cost-effective control of motor speed and torque. Four quadrant, full bridge power output stages provide for solid state motor reversing and full regenerative braking power. Model 1237 provides additional features for special industrial applications. Application: Curtis PMC Models 1237 is designed for large permanent magnet motors, such as those used by large mobility aids, scrubbers, personnel carriers, small golf cars, small walkies etc. Features: Full bridge power MOSFET design provides infinitely variable forward, reverse, drive and brake control; silent high frequency and high efficiency operation. • Programmable through the Curtis Model 1311 or Model 1314 handheld programmer, an optional universal unit used for programming, testing and diagnostics. • Complete diagnostics also available through the status LED. • Fully compliant with all applicable international standards and TUV requirements. • Available for wig-wag (center off) and single ended (speed pot and direction switch) throttles for both standard full stroke and restricted range 5k? potentiometers. Also accepts 0–5V throttle signals. • Throttle calibration mode aids the mechanical centering of the throttle using the 1311 Programmer to enter the mode. The horn will sound and the status LED will be off whenever the throttle is outside the neutral band. • MultiMode® input selects between two different operating modes. MultiMode® allows changes in speed, accel, decel, current limit, and IR compensation. This allows optimization of vehicle characteristics in each mode, for example indoor/outdoor. • Speed limit input provides additional variable speed limiting, in both mode ranges, with an external pot. • Linear acceleration and deceleration with softened response for smooth operation. • Current limited in both driving and regenerative braking. • Load compensation stabilizes speed on ramps and over obstacles. Compensates for battery voltage, voltage drops, and motor resistance. • High pedal disable (HPD) function monitors status of the throttle during turn on and prevents operation until the throttle has been returned to neutral. • Power off decel provides a controlled deceleration if the key switch is turned off while driving. • Comprehensive fault detect function monitors main contactor, output stage, throttle demand vs. output, etc. • Throttle fault circuitry shuts off controller if throttle signal goes out of range for any reason. • Missing brake detector forces neutral in the event of an open brake circuit (programmable). • Anti-rollback/roll forward circuitry sets brake delay according to speed and direction for improved braking response and minimized rollback on hills, etc. • Over-current protected brake driver protects the controller from shorts in the brake or its wiring. This low side output driver may also be programmed for side broom or brush contactor, hour meter, BDI enable, etc. • Brake PWM allows the brake driver to be programmed to a reduced holding voltage. • Reverse output drives a piezo beeper (customer supplied) in reverse. • “Push Too Fast” feature allows motor to coast with controller off and brake released. Pushing too fast automatically and safely shorts the motor to limit maximum coasting speed. • Push input electrically releases brake for key-on pushing (requires that the vehicle be stopped first). • Inhibit input disables the controller and puts the vehicle in a safe state during charging, etc. • Power saver deactivates the main relay after 25 seconds and entire controller after 25 minutes of non-operation. • Under voltage cutback function protects against low battery voltage. • Thermally protected and compensated for stable output and over-temperature protection. • Reverse polarity protected (battery input). • SRO input sequencing options. • Emergency reverse (belly button) input causes immediate reversal. • Programmable high side driver output for brake light, belly button check, BDI enable, hourmeter, side broom contactor, etc.
