Specification:

CURTIS 1209M Controller Datasheet
Nominal input voltage: 48V or 72V (programmable)
Current rating 2minute: 400A
Attention: The buyer should confirm with the seller the battery system voltage, current rate and the throttle type (0-5kΩ, 5k-0Ω or 0 – 5V).
By defaut, we will deliver the controller of setting of 48V / 450A / 0-5kΩ.

Feature 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.
