Our pulse generators and PWM circuits are quality, versatile modules designed to be multifunctional and are an essential tool for anyone working with electromagnetism, electrolysis, or any other pulsed oscillation applications. The have adjustable frequency, and adjustable duty, with a range of features such as linking them together for making complex control systems. There are several versions available to meet the needs of different voltage and current ranges, or high switching speeds. Check the Power Pulse Modulator Comparison Guide for details of the differences between the modules.
