40A CCPWM MAX LOAD 55A 12V DC 32bit Cortex processor Constant Current Pulse Width Modulator for HHO generator Undestroyable & Waterproof with LCD AMP Water Level Control
Automatic Start/Stop Constant current PWM for HHO generator In 32bit Cortex processor + LCD digital amp ammeter + electrolyte level + Waterproof Heavy Duty.
- 40A Constant current HHO PWM + LCD digital amp ammeter + electrolyte level Waterproof;
- Peak current: 55A (above this the PWM does not get damaged just stop and give you a sign because of the large current);
- High-efficiency CCPWM with AMP meter and full protection!
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 originally 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 consumption gets growing. If you have the current meter in the car it is okay you just modify the duty cycle every time. Do not you think you should have a fully automatic system? A fully 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 of the bad circuit design. Maybe you are an HHO reseller. 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 don't need digital clamp meter or shunt to measure the current!
The HHO system installation you adjust the current and leave the PWM forever. If you place LED (see in the wiring diagram) on your car dashboard, you can get full up to date information about your HHO system.
- 100% ON System okey the production is ok.
- Blinking slowly: Low water warning you will need a water refill.
- Blinking fast: Low production or error. You need to check your electrolyte.
To sense, the electrolyte level uses a water level switch. PWM will only start 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 don't want to 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 key switch voltage needs to be higher than the adjusted voltage.
