Curtis AC F4 48V 375A inverter

The Curtis AC F4-A family of controllers with dual ARM Cortex microprocessors allows accurate speed and torque control of three-phase AC induction motors and PMAC motors. It can be used to control traction motors, hydraulic pump motors, and generators in mobile applications such as construction machinery, agricultural machinery, earthmoving equipment, freight and passenger transport, and marine applications.

In addition to highly advanced motor control, the AC F4-A model features powerful vehicle control functions. All I/O channels are multi-functional and configurable up to:

• 27 digital inputs
• 9 analog inputs
• 2 potentiometer inputs
• 7 outputs
