DC to 100kHz Adjustable Frequency, 0% to 100% Duty, 3.5A Current, Switching Voltage up to 400V
The PWM-OCBI 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 high voltage circuits such as for driving high voltage coils. 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 knobs covers available seperately.
