Clasic Max 067 PWM

This HD-PWM will meet the needs of most all single and double cells used for hydrogen boosting and is made to be superior to the popular 30 amp Max 066 PWM.

This PWM is NOT a Constant Current PWM


* Frequency adjustment 100 Hz fixed or 300-3,000 Hz adjustable
* More powerful output transistors
* 8 on board male spade connectors for better power transfer
* Larger heat sinks
* Wire re-enforced circuit board traces
* Larger mosfet pre driver
* Power LED
* Wide operating range 8-30 volts
* Note: (fan is rated for 10-18 volts)

With a Pulse Width Modulator, your HHO booster will run cooler and make more monoatomic hydrogen than just using direct current alone. 

Monatomic hydrogen has a greater ability to increase fuel mileage than diatomic (REG) hydrogen.

With a PWM you can use a slightly stronger electrolight (KOH) this will prevent freezing

This unit is fully tested and ready to be installed Guaranteed No DOA
30 day warranty:

If this HD- PWM fails within 30 days, we will replace it at no cost to you. You will need to pay for shipping to us.
We will not replace the PWM if you connect the + and - wires backwards and burn out the reversing diode.
