Product Information
DC to 1.5MHz Adjustable Frequency, 0% to 100% Duty, 14A Current, Switching Voltage up to 50V
The PWM-OCX is a high quality, durable, adjustable DC pulse generator designed for providing an easy way to adjust power to devices or to pulse them at a wide range of frequencies and pulse times. This version is designed primarily for use in low voltage circuits such as for electrolysis or lighting. The frequency is independently adjustable to the pulse width which can be varied smoothly from 0% to 100%. It is designed to fit a wide range of applications and be fully adjustable so that it can be used for many different tasks. These units can be linked together and used to complete a variety of tasks, or linked to our other circuits in all sorts of ways. The modules can also be linked together in a master/slave setup, and the pulse width (duty cycle) can be adjusted by an external analogue source. The circuit is made in England on a high quality PCB with double layer design, plated thru holes (PTH), and 2oz copper (twice as much as standard circuits) for durability and performance. Control knob covers available seperately.
This model can very rapidly switch between on/off states compared to other pulse circuits. This high dI/dt is great for generating fast optical pulses in lasers or large LEDs, or for generating ultrasonic pulses in piezo transducers.
