NEW*
40 Amp
Constant
Current PWM
This
is the all new Constant Current PWM
Made
by Hydrogen Boost Now.Com
Works
Great On Dry Cells Between 13-27 plates
Just
Set It And Forget It
After
almost a year of testing, the all new 40 amp Constant
Current PWM is ready for sale.
We
at Hydrogen Boost Now wanted a new PWM that would
meet the needs of today's power hungry
dry
cells and have the features that are not available
from most others PWM's.
This
PWM was made to meet those needs.
This
PWM is easy to use,
Prevents
thermal runaway,
Improves
cold starting times,
Produces
more monotomic hydrogen,
Improves the efficiency and the life span of your
Dry Cell.
What
Is A Constant Current Pulse Width Modulator?
A
constant current PWM will automatically adjust the
pulse width from the PWM
so
that it will output a constant level of current regardless
of how large the load is.
In
other words
Set
this PWM to 30 amps and the current will always be
30 amps (RMS)
This
compensates for:
Voltage
changes in the charging system,
Temperature
changes in your cell,
Different
levels of KOH in your cell.
This
makes it much easier to set up your cell and the end
user is less likely to
to
add too much KOH and burn out fuses,
pop circuit breakers, or melt down the cell and wires.
Available
in green or bright blue
.......
This
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
in Green
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
water out
..........*
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
cell setup
.........
*
Professionally assembled with surface mount and through
hole parts, no hand soldering

90
Day Warranty
If
this PWM fails within 90 days,
we will replace it at no cost to you.
You will need to pay for shipping to us.
You
must use a fuse to protect the PWM.
We will not replace the PWM if you connect the
+ and -
wires backwards or connect the PWM to a load
greater than 60 amps.
