NEW*
40 Amp
Constant
Current PWM
With
Pre-set or Onboard Current Adjust
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
This
PWM can be pre-set by us for any current level
Between 15-40 amps or you can set it youself with
your amp gauge.
You
don't need a amp gauge with a constant current PWM
Just
set the current with your amp gauge and that's it.
Current
will stay within 1 amp of set point at 30 amps
This
PWM is easy to use and will..
Prevent
thermal runaway,
Improve
cold starting times,
Produce
more monotomic hydrogen,
Improve 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
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.

.......
This
PWM has many new features:
..........*
Constant Current... Current stays within .5 - 1 amp
of set point (average)
..........*
A remote port for a dash mounted water light and power
switch (Not available until August)
..........*
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 60 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
.........
*
Full 90 day warranty

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.

Buyer
Beware
Some of the other constant current PWM's on the market
are
based on a flawed design floating around on the internet.
This
flawed design was posted back in 1998.
This
old design does not use true pulse width modulation
and
can waste
as much as 50% of the energy that is passing through
the PWM .
Only
true pulse width modification can pass large amounts
of current without overheating.
Unfortunately,
this flawed design can be made at home so there are
many out there.
The
old design easy to recognize.
It uses a very large Pentium heat sink and fan.
Most
come in a metal box with a large fan.
The
large heat sink is needed because of all the power
wasted when in current limiting mode.
This
unit gets very hot and is only good for small loads.
We
did not use this old design.
Our
PWM uses only true Pulse Width Modification and at
30 amps, is over 98% efficient.
Our
PWM makes very little heat. This is why we can use
a plastic box.
At loads less than 30 amps, this PWM needs no fan
at all.
The
fan is there for loads between 30 to 60 amps.
