H2O2-PWM Plus V2 - Pulse Width Modulation With ACL

A HHO Pulse Width Modulation Controller with Auto Current Limiting (ACL). This PWM adds a real punch to the original open source project. It utilizes a Pulse Width Modulation Chip to Make the Switching MosFet's run cooler. It does this by reducing the time it takes to turn on and off the MosFets. It is capable of running 8 MosFets so the sky is the limit for current control! This Open Source  board is based on the CCPWM V2 & CCPWM V2H originally designed by Zero Fossil Fuel. Version 2.1.9 is out and adds the following minor improvements: Optional Push button Switch for JP3, Fan plug now supports 12Vdc, and 10Vdc, so that 12V Fans can be used with 24Vdc Truck Systems. Improved Silk Screen.
