55A Constant current HHO PWM in waterproof case + LCD display
If you only need only the PWM PCBs (printed circuit board) without case for your special setup, you can find it in my other items.
Why buy a Constant Current PWM?
A true Constant Current PWM will automatically adjust
the Pulse Width to the current you set regardless of the load.
Hydrogen cells are famous for getting hot and asking for more power than what is safe or desirable for the system. Adding a constant current PWM will
prevent this thermal runaway scenario
and improve the quality of Hydrogen that your cell is producing.
Why do not buy an
ordinary
PWM?
The ordinary PWMs which made for originaly motor speed controlling are not the best solution for the job. Yes, they are cheaper some bucks but they only adjust the duty cycle. Every time when your electrolyte gets warming (after some minutes they are) the electrolyte resistance starts to reducing and your current consuption gets growing. If you have current meter in the car it is okey you just modify the duty cycle every time. Do not you think you should have a fully automatic system? A full automatic system where your only task to admiring the landscape.
Those PWMs have also a large warming that even though they have many transistors. This is because the bad circuit design.
Maybe you are a HHO preseller. Do not you think you may sell a
quality PWM? It is not too late to change!
If you agree with these than you find your PWM!
This PWM will automatically adjust to maintain a Constant Current
on any cell that draws less than 55 amps!
You dont need digital clamp meter or shunt to measure the current!
LCD display:
By the HHO system installation you adjust the current and leave the PWM forever.
If you place the LCD display on your car dashboard, you can get full up to date information about your HHO system. It is very usefull because you can supervise your HHO system on your dashboard. The working current the working conditions and the water level.
LCD display is also wery usefull if you want to meke your HHO kit a unique on the market!
To sense the electrolyte level use a water level switch. PWM will only starts when you close the water level switch. Otherwise the display shows "LOV".
The PWM only start when you supply from the key switch terminal (see the wiring diagram). If you dont want tu use key switch just wire this input to the +12V.
If the supply voltage is higher than the P3 potentiometer the PWM starts and switches the relay. Otherwise a blinking dot shows a "stand-by" mode. If you turn down the P3 the voltage sensing mode is disabled and the PWM starts. Otherwise the keyswitch voltage needs to be higher than the adjusted voltage.
TECHNICAL SPECIFICATIONS:
-
Connection on the M4 screws with M4 ring reminals
- Internal potentiometer for adjust HHO cell current between 0-40A
- Peak current: 55A (
above this the PWM does not get damaged just stop and give you a sign because of the large current)
- Working voltage 12V or 24V (Please let us know which one you need.)
- Current Adjustable from 0 to 40 amps
- Output short cut protection
- Very small warming (at 20A the temperature is the ambient +15°C)
- 3mm thick sealed aluminium waterproof case
- Case dimensions: 115 x 68 x 30mm
