PWM Controls offers reliable, versatile proportional valve drivers designed for precise control of hydraulic actuators.

A Wireless Universal Driver can control one dual solenoid valve or two independent single solenoid valves, proportionally to analogue input command signals. The input signals can be selected from the industry standard 0-10V, 4-20mA, +/-10V or any sub-ranges thereof. In addition to that, the Driver accepts ON/OFF signals for other functions. The solenoid outputs are pulse width modulated, with frequency adjustable from 33 to 1000Hz, up to 4A. The Driver can control the output current or the output duty cycle, proportional to the input.

Test drive the WiFi User Interface!

The WiFi User Interface is used to monitor input and output signals or to configure and tune up the driver to the application. It is not needed for normal operation. It is compatible with most internet enabled devices and browsers (no app needed).

The MONITOR screen shows real time inputs, outputs and other information	The SETUP screen allows the operator to view and modify the settings of the driver

Legacy Bluetooth User Interface: PVD4R01 DIN rail mounted, compatible with Android phones/tablets and Windows PC laptops/desktops, requires installation of the DriverLink app. Download it here for Android or Windows.

The result of 20 years of experience, our Convertible Proportional Valve Drivers satisfy the demands of industry leaders for smooth and precise control of hydraulic valves. Click here for Testimonials from our customers.

ADVANTAGES:

• The digital display confirms proper operation at a glance: it shows the input signal directly in Volts or mA, the output current directly in Amps or the driver settings names and values
• Only need one part number for input signals 0-5V, 0-10V, 0-20mA or 4-20mA, for coils rated 1A, 2A or 3A and power supply 12V or 24V
• The only tool you need to install and tune up is a standard screwdriver
• Better linearity and control
• More effective dither
• Easy to read and duplicate settings
• Diagnosis possible even over the phone
• Insensitive to vibrations

PWM Controls Inc. was established in 2006 with the purpose of providing the industry with the most advanced, reliable and user-friendly proportional valve drivers. Proudly made in Canada, our design is the result of increasing demand among industry leaders for superior products. They are engineered to satisfy the stringent requirements of an evolving industry; their specifications and innovative features are a reflection of 25+ years of electro-hydraulic controls experience and valuable user feedback.

The proportional valve driver - also referred to as a PWM (Pulse Width Modulation) amplifier card, controller, chopper, or power plug - is an electronic device powered by a regulated or unregulated DC power supply or a battery (in mobile applications). It receives small power signals from a potentiometer, joystick, PLC, analogue output card, computer or other control device. It then delivers a high power controlled current to the solenoid of a proportional valve. Through pressure or flow, it regulates the motion of a hydraulic actuator.
