OVERVIEW
OVERVIEW
Curtis PMC Model 1204X/1205X and 1209/1221 electronic motor speed
controllers are designed to provide smooth, silent, cost-effective control of motor
speed and torque on a wide variety of industrial electric vehicles.
Like all Curtis PMC 1200 series controllers, the 1204X/1205X and 1209/1221
models offer superior operator control of the vehicle’s motor drive speed. Key
features of these controllers include:
✓ Infinitely variable drive and brake control
✓ Power MOSFET design provides high efficiency (for reduced motor and
battery losses) and silent operation
✓ High pedal disable (HPD) function monitors throttle status during turn-on
and prevents operation until throttle has been returned to neutral [optional
feature]
✓ Thermal protection and compensation circuit provides both under-
temperature and overtemperature cutback, as well as steady current limit
throughout the entire operating range
✓ Undervoltage cutback function protects against low battery voltage, includ-
ing low voltage caused by external loads
