We offer the best PWM's anywhere. We have 30 amp and 50 amp Pwm's. Pulse Width Modulators for hydrogen cells, are a must for making the best Hydrogen injected into a Combustion Engine. A PWM is just an electronic switch that turns on and off at a very fast rate of speed varying the percentage of time on vs off. To the load it appears smooth because it's so fast. Why do I need a PWM for HHO? It's to prevent thermal runaway. After your cell warms up, it will increase the amps drawn. We must control this, so the current draw will not damage the electrical system. We Carry the Extreme 50 Amp Bare Bones, an Extreme 30 Amp analog, an Extreme 50 Amp analog, a Pro 30 Amp Digital, a Pro 50 Amp digital and will soon have a Pro 100 Amp digital. Guaranteed NO DOA, we test each unit before shipping.
