is the all new Constant Current PWM
by Hydrogen Boost Now.Com
Great On Dry Cells Between 13-27 plates
Set It And Forget It
almost a year of testing, the all new 40 amp Constant
Current PWM is ready for sale.
at Hydrogen Boost Now wanted a new PWM that would
meet the needs of today's power hungry
cells and have the features that are not available
from most others PWM's.
PWM was made to meet those needs.
PWM is easy to use,
cold starting times,
more monotomic hydrogen,
Improves the efficiency and the life span of your
Is A Constant Current Pulse Width Modulator?
constant current PWM will automatically adjust the
pulse width from the PWM
that it will output a constant level of current regardless
of how large the load is.
this PWM to 30 amps and the current will always be
30 amps (RMS)
changes in the charging system,
changes in your cell,
levels of KOH in your cell.
makes it much easier to set up your cell and the end
user is less likely to
add too much KOH and burn out fuses,
pop circuit breakers, or melt down the cell and wires.

PWM has many new features:
Constant Current... Current stays within .5 - 1 amp
of set point (average)
Digital amp gauge pre-calibrated at 30 amps (Available
or Bright Blue)
A remote port for a dash mounted water light and power
switch (Not available until 2012)
Very strong, easy to use bolt on connectors rated
at 60+ amps
Extra thick circuit board and large mosfet transistors
Internal fan to keep the PWM cool but also helps keeps
Frequency adjustable in the range that works best
for the Dry Cell (75Hz-1,500Hz)
12 Volt switched output for an EFIE or other computer
controlled device (For remote)
High peak power rating for large Dry Cells (This PWM
was tested with a 65 amp load)
PWM will power on and off without a relay (we recommend
to always use a relay for safety)
Two pages instructions to help with installing and
Professionally assembled with surface mount and through
hole parts, no hand soldering
