"If it has a Fan on it --- it
could be over rated"
Do you really need a PWM? Not really, but it is nice to be
able to control the output of your hydrogen generator - from your dashboard.
During winter months, we need more electrolyte in the water because cold
water does not conduct electricity as well. In summer months, we need less
electrolyte in the water because hot water conducts electricity much better
than cold water. During periods of hot and cold, you are screwed; unless you
have a PWM. The PWM allows you to use more electrolyte, but still control the output of the HHO generator.
The purpose of the PWM is to pulse the DC voltage to the
cell. Pulsing the voltage turns the current on off on off on off, thus
reducing the heat caused by constant current flow. In other words, just as
the current starts to flow, it gets stopped. The series of starts and stops
happen instantaneously.
In addition, the PWM allows you to regulate the amperage
(current). This provides runaway control over the cell. The longer the cell
runs on DC, the hotter the water will get, the higher the amps will go.
Eventually you will blow a fuse, pop a breaker. The PWM solves that problem.
Some PWM's are self regulating; meaning, they are made to
operate at a constant amperage, even as the water gets hotter. You set the
maximum output, and forget it.
Please be advised: A PWM will not increase your Hydrogen
Generators HHO output. It will do just the opposite. It will restrict the
output; based on what you set it to produce.
If you purchase a PWM, pay
close attention to the output rating. Most sellers do not tell you the
"Continuous" Output. If they say it is a 30 amp PWM, in most cases that is a
Peak or Maximum output rating. You can not operate at maximum very long. If
you want or need a constant 30 amp output - make sure the PWM you purchase
can withstand that output continuously. It is better to have to much PWM,
than not enough; the output is adjustable.

80 Amp Continuous - DC
PWM (very reliable)
Supply Voltage: 12 to 36
Volts DC
Load Current: 80 AMPS
Continuously, with Resistance and Inductive loads; 120 AMPS for short
periods of acceleration (up to 10 sec.)
