PWM 40A - Current Limitin
Latest Revision of New Circuit Design
This box gives enthusiasts good results and a fair price. First
it's constructed with a plastic box to help keeps costs down, but
it offers an externally adjustable knob that controls the 'current
limit'. This allows for on the fly adjustments, and it
automatically maintains whatever HHO production level you choose.
This is what makes it a 'constant current' design. The duty-cycle
is what manages the unit and automatically steps down to keep your
current draw exactly where you want it. For advanced users, the
frequency is also adjustable with a one-turn pot inside for those
who desire to make those adjustments as well.
While most Pulse Width Modulators adjust the current to the HHO
generator, they do NOT self adjust as the unit increases its
operating temperature. This can lead to a runaway reaction and
overheating your HHO system. This unit is in fact a current
This PWM gives you both advantages. First, it 'pulses' the current to the
HHO generator making more effective use of the current draw.
Secondly, it automatically maintains the amperage you set when the
unit is first turned on.
As your driving day continues and operating temperatures rise, the
PWM automatically holds and limits the total current the unit can
draw. This is done by reducing the 'duty cycle' which is the percentage
of time the pulse in 'on' during every second.
Designed for up to 40 amp draws, It's rugged and it delivers. But
most importantly, you don't have to monitor your HHO generators'
current use all the time.
PWMs are an upgrade to the standard HHO configurations and come
standard on all the Premiere system choices.
