Critical Velocity manufactures high quality PWM motor controls ranging from simple unidirectional speed controls to a full-featured stand-alone stepper motor controller with a jog-dial user interface. Our growing line of motor controls feature a choice of simple interfaces designed for easy integration into new or existing systems:

• Analog control voltages can be used with a potentiometer or analog output modules.


• Push button inputs allow for a simple "push to speed up" or "push to slow down" interface.


• Digital inputs allow straightforward integration with PLCs and microcontrollers.

We also offer resistive load controllers specifically designed to control power to non-inductive devices. Constant current and current limiting ensure safe operation even with Negative Temperature Coefficient loads.

In addition, configurable PWM solenoid valve controllers enable proportional flow control using low cost solenoid valves.
