    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
    • 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
    • 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
    • Simple 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.
