Curtis Controller model 1231C-8601, 96-144VDC, 500 Amps max, 0 to 5 k/ohm input. 

Used for on-road vehicles and other Higher Voltage, High Amp Applications. Infinitely variable throttle control, high pot input lockout, low voltage and high temperature current cutback. The "C" models use frequency shifting to reduce the operating frequency from 15kHz when the PWM output is less than ~15%. Frequency shifting improves the current limit control and also

helps protect the controller when the motor is in near-stall conditions.

This is one of the most popular controllers used in EV conversions.
