Power Control Module

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 Important: Minimum Safety Circuitry for HHO Installs.  Please see that article for a complete description of this device.

Comes with 6' of 10 gauge wire, for connection to the battery and your cell.
