OVERVIEW
Curtis PMC 1207/1207A programmable motor speed controllers provide effi-
cient, cost-effective, and simple-to-install control for a variety of small electric
vehicles. Typical applications include walkie fork/pallet trucks, mini personnel
carriers, and sweepers. The microprocessor-based logic section combined with a
proven MOSFET power section gives the 1207/1207A controllers high power
and advanced features in a simple, compact package. The optional handheld
programmer enables the user to set parameters, conduct tests, and obtain diag-
nostic information quickly and easily.

Like all Curtis PMC motor controllers, the 1207 and 1207A models offer
superior operator control of the vehicle’s motor drive speed. Features include:
✓ Power MOSFET design, providing
• infinitely variable drive and plug brake control
• silent high-frequency operation
• high efficiency (for reduced motor and battery losses)
✓ Compact size
✓ Overvoltage and undervoltage protection
✓ Thermal protection and compensation circuitry provides undertemperature
cutback, constant current limit, and linear rollback in overtemperature—
thus preventing sudden power loss regardless of thermal conditions
