The KZX1250 is a brand new PWM, not to be confused with any other. The
KZX1250 has an on board computer with advanced features that make it
virtually bulletproof and safe to use. No other PWM can match it.
Don't trust just any PWM under your hood. With the KZX1250 you know you
are safe and you know your PWM is designed to handle tough situations
that most others were never designed to.
Start out with a computer that digitally generates the pulses. Send the
output through Schmidt triggers to get a sharp square wave which is then
fed to a high speed MOSFET driver and finally to 8 Power-Pak MOSFET's
through their own individual driving resistors. The efficient design
means it runs super cool. How cool is that? The KZX1250 does not have a
heat sink because it just does not get very hot. It just uses a small
40mm fan for cooling. With 50 amps going through it, at maximum
frequency, the KZX1250 enclosure does not even get warm and the
protruding circuit board only gets luke warm; you can squeeze it between
your two fingers without getting burned!
As you'll see in the video, the KZX1250 has short circuit protection.
Automotive fuses can take up to 100 milliseconds (after its rated
current is reached) before opening. That's a tenth of a second; which
might seem fast to you, but to semiconductors, it is like a year! Fuses
are activated by heat and the same heat that the fuse sees is the heat
that the MOSFET's see as well. The KZX1250 opens the circuit in less
than 1 millisecond so it's virtually impossible to damage it due to a
short circuit! Why waste your money on fuses which cost $2 a pop? ...and
why subject your MOSFET's to irreversiible damage?
The KZX1250's thermal protection means you have protection against
certain situations that could turn your car into an inferno. The fan on
a PWM is there for a reason, to keep the MOSFET's from burning up; yet
the fan being a mechanical device is the most vulnerable component on
the board. What happens when the fan gets clogged with dust and dirt or
if it just stops working altogether? Who will be there to turn off the
MOSFETs? The KZX1250 has a temperature sensor that makes sure the
temperature doesn't rise above 167 F (75c). If it does, it is quickly
turned off and an error code is displayed.
If you're going to do HHO, you might as well do it right.

Be smart and be safe; get the KZX1250.
Attention: At
present, there is only one place to purchase the PWM. Their site is difficult to navigate.
If the PWM is backordered, you
will have to fill out a Business Inquiry Form -- on that web site - and
wait for them to respond. If you need help, let me know.
ADI Corp. Business Inquiries (while their web-site is under maintenance)

claim and how it will negatively affect your system instead. http://adicorp.net/php/articles.php?id=2
