The motors are driven using high-efficiency Power MOSFET transistors controlled using
Pulse Width Modulation (PWM) at 16kHz. The AX2500/2850 power stages can operate
from 12 to 40VDC and can sustain up to 120A of controlled current, delivering up to
4,800W (approximately 6 HP) of useful power to each motor.

The many programmable options of the AX2500/2850 are easily configured using one-
touch Program and Set buttons and a 7-segment LED display. Once programmed, the con-
figuration data are stored in the controller's non-volatile memory, eliminating the need for
cumbersome and unreliable jumpers.
