1207B-4102 is the upgraded version of 1207/1207A DC Series Motor Controllers. 1207B-4102 is fully compatible with the old 1207/1207A controllers, ideal for replacing 1207A-41xx controller (for example 1207A-4107). 

The 1207B controller accepts a variety of throttle inputs, through various combinations of its four throttle input pins. Throttle types:

• Type 1 = 5kΩ–0
• Type 2 = 0–5V, 3-wire pot, and electronic throttles
• Type 3 = 0–5kΩ throttles

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 1313-4401 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 1313-4401 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
• 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.
