Overview:

CURTIS PMC 1207B programmable motor speed controllers are the latest upgraded version of popular 1207A controllers. The CURTIS 1207B programmable motor speed controller provides efficient, 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 1207B controller high power and advanced features in a simple, compact package.
The CURTIS programmers (Model 1313-4331 Handheld Programmer or 1314 PC Programming Station with 1309 USB Interface) enable the user to set parameters, conduct tests, and obtain diagnostic information quickly and easily.

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
CURTIS 1313-4331 Handheld Programmer (optional) provides a full set of parameter and function settings, as does the CURTIS 1314 PC Programming Station (optional)
Diagnostic and test information for the controller - and other system components - readily available both on-board and through the programmer
On-board potentiometers allow direct manual adjustment of acceleration rate, creep speed, maximum speed, plug current, and main current limit (1207 single-mode models only)
Circuitry and software detects faults in the throttle circuit, MOSFET drive circuit, MOSFET transistors, contactor drivers, and contactors - ensuring that the controller meets EEC fault detect requirements
Input sequencing options include neutral start and static return to off (SRO)
Microprocessor-controlled contactor sequencing provides true arcless contactor switching
Smooth, controlled plug braking - with either variable (throttle-dependent) or fixed plug current limit
Neutral braking option provides automatic plug braking in neutral
MultiMode™ input selects between two different operating modes, thus allowing optimization of vehicle characteristics for different driving conditions
Emergency reverse (belly button switch) with a single input Ramp-start feature provides full power for starting on ramps
Simle contactor and switch wiring, with coil drivers monitored for faults - thus ensuring fail-safe operation
Flexible throttle circuitry accommodates a variety of throttle types
Programmable "ramp shape" (static throttle map) provides flexibility in selecting throttle response feel
Connections made by solid copper power busses with a polarized Molex connector for control signals
Solid, well-protected construction - with an aluminum mounting plate and injection-molded cover.
