This device is used to control the power to your HHO cell. It provides a way to switch the cell on and off, using very low current. The actual switching of the main current to the cell is done with a relay. This allows you to control the cell using the fuel pump relay, so that the cell is only operating when the engine is actually running. This is a vital safety concern. You can also add a remote switch for your HHO system using any available switch and 2 small wires. Finally, it has a built in shunt so that you can read the amperage you are drawing by measuring the voltage between 2 terminals on the circuit board.
This is the Power Control Module described in the article
