It is important to make your Cell safe to use.

 

If, for any reason, you need to turn the cell "on or off" while driving, you should have a conveniently located switch that can be reached from the drivers seat.

I match my circuit breaker amp rating with my PWM for safety and control of the cell. I use a relay that is capable of handling the PWM output rating.

  • The relay carries the amperage load. It can have a higher amp rating than the PWM.
  • The circuit breaker protects the PWM. It can have a lower amp rating than the PWM, but not a higher amp rating.

Note: If you plan to use a Fuse, the fuse should be rated at 1.5 times the expected maximum current flow. If the fuse is rated right at the maximum current flow, then it will usually blow after a period of time as it becomes warm. Fuses come in specific sizes, so you may need to select the next nearest size.

For example, if your radio is rated for 9 Amps maximum, then the fuse should be 9 x 1.5 = 13.5 A. Since there are no 13.5A fuses, use a 15A fuse.

80 Amp Relay,  (very reliable)

Your Relay is used to connect your battery voltage to the cell. It needs to be capable of handling all of the amperage your cell uses, and then some.

  • High Current Relays are the most reliable and efficient way to turn on your HHO Cell
  • Compatible with all types of alternators and charging systems
  • Wire it to your ignition switch.
  • Water Resistant black phenolic plastic
  • 100,000 Mechanical Cycle Life

PWM's

 

PWM - Pulse Width Modulators.

Use to Control the Amperage. Several models are available.
It is suggested to use a model that is rated Constant Current (CC)

 

 
   

Volo Chip

 

 

Volo HHO Performance Chips  (for OBD II computers)

This chip has been specifically tuned for the needs of HHO generator equipped vehicles. The FS2 is dynamic - which means the FS2 will consider oxygen levels in the exhaust, along with engine speed and load, intake air temperature and volume, and many other variables to determine the most efficient fuel delivery rate and timing at up to 256 separate load points.

When using HHO as a fuel supplement, the FS2 will adjust fuel delivery and timing to optimize efficiency.

When HHO is disabled, the FS2 will automatically re-adjust and switch to highly efficient, non-HHO enhanced maps.

The FS2 is a vehicle specific, custom programmed 20MHz Microcontroller. It utilizes its high speed serial input/output to communicate directly with the ECU through the OBD-II port.

Amp meters require a SHUNT. If the shunt is not built in, you will need one that matches your meters mv rating. Amp Gauges usually have a built-in shunt.

100 Amp 75mv DC Shunt  (the mv must match the amp meter's mv rating)

200 Amp is also available

Shunt: The shunt passes the DC current to the cell. It also allows you to measure the current. If you have a 100 amp meter, you need at least a 100 amp shunt (or higher); plan for the capabilities of your meter.

DC to DC Converter Isolator:   $12.50

Needed to power your Digital Meters

Lets you turn your 12 volts DC into an isolated 5 volts DC (makes it look like a different power source).

A Digital amp gauge needs an isolated battery source. If you don't want to use the Isolator, use a 9 volt battery to power your digital gauge. You will have to change batteries when they run down.

5Volt DC Power Supply. Turns 12v into 5volts.

This is 5V power regulator designed by using a famous voltage regulator IC 7805. Output is very stable and smooth. Fluctuation, noise, spike all eliminated. The input can take a range from 7v to 36v dc.

It's an ideal candidate for being used for a Digital Panel Meter or other device driven by 5V DC at low current.

Clamp-on Ammeter

Every HHO experimenter needs a clamp-on ammeter. It is your responsibility to know how many amps of electrical current your cell is drawing. It is not a guessing game. These meters vary in price, but start around $25.

  • Make sure your meter can read DC Amps
  • Use it to troubleshoot bad connections
  • Use it to test your electrolyte water mix. Too much electrolyte will make for a bad day.
