40 AMP PWM power controller for HHO kits

For an inexpensive PWM to control power to your HHO kit- these are a great solution. If you have one of our kits, you can use these with the Digital AMP Gauge we include, so you can monitor precise current control of your hho generator.

This is a completely assembled 40 amp PWM with 6 power MOSFETS inside to divide up the power to keep it from overheating, so a fan is not needed. That allows a very nice compact box that is easy to install and hook up. These are nice units and come with ventilation slots cut into the sides to allow air to be drawn up and over the cooling heat sinks.

They come with a single dial for current control, 6 individual mosfets and heat sinks inside. Operates from 12 volts up to 30 volts DC. It has 4 connections inside the box at the back, making installation simple. Two of the screws are for POWER IN from the battery, and the other two are POWER OUT to the HHO generator.

TO HOOK UP: Simply unscrew the terminal connector, strip 3/8" insulation off the wire, slip it in under the clamp, and tighten the screw. 

WHAT DOES IT DO? The  PWM  has become the new standard of current control for advanced HHO Kit enthusiasts. Rather than just straight current flowing into your generator (Brute Force), these PWM boards control a "Pulsed Current" by pulsing off and on rapidly. Some pulse at a fixed frequency, and have adjustable current. Others allow both current and frequency to be controlled. Some argue that the frequency is critical, but we have found no evidence that it makes any difference in all of our testing.

There is a definite advantage though, to using a Pulse Width Modulator to more precisely control the current to your HHO kit. You may find that best mileage is at 17 amps, or 22, or 25...etc. Having that extra control makes it nicer for dialing in your HHO generator to the perfect setting.

DO I NEED ONE? The HHO kits we sell will operate with or without a PWM power controller, but they do offer more precise tuning of your hho generator which can allow for best mileage and performance gains. 

However, You should definitely use a PWM for your HHO kit if you live in frigid climates or areas of extreme freezing area. By increasing the electrolyte concentration and controlling current with a good PWM, you can prevent freezing to - 40 degrees Fahrenheit! We show you how to set up properly in our installation kit manuals.

 

Shipping

All orders over $100 within the U.S. qualify for FREE SHIPPING! Simply add the HHO kit of your choice to your cart and you will automatically get free shipping with FedEx Ground when you are in the contiguous U.S.! Orders to PO Box addresses, APO/FPO, Alaska, Hawaii, and Puerto Rico are fulfilled with USPS Parcel Post. After your order is processed, you will receive an email with confirmation of your purchase and address. Orders are generally shipped within 1-2 business days after the order is placed. Once it has shipped, you will be emailed the tracking number.

It generally takes 2 to 7 days after your order is processed to receive your kit or parts via FedEx Ground. Orders sent via USPS Priority usually take 2-3 days, USPS Parcel Post generally take 1-3 weeks on average, unless you opt for USPS International Express which is normally 3-5 days.

Canadian Orders:
We gladly ship to Canada but you will be expected to cover all brokerage and handling fees. Canada Post may also require a small import tax at your door.

International Orders (outside the US and Canada):
We ship to many countries outside the US and Canada, but do not currently ship to Iran, Afghanistan, or China. If you are unsure, please email us and ask. Overseas packages are always shipped via USPS International Priority (7-14 days but can take longer), or International Express which is guaranteed 3-5 days (but costs $25 per package additionally). Depending on country and kit selected, prices range from $49 to $125 on average. We do not use UPS or FEDEX for overseas shipments as they cost as much as $100 more than USPS. As with Canada, you will be expected to cover all brokerage and handling fees of your own country.

Third Party Freight

Occasionally we will have a customer attempt to purchase our kits and request a third party freight company of their choice. It is our company policy to NOT accept these type of orders. We only use our pre-approved postal and shipping companies, no exceptions.

Returns

 What If The HHO Kit Doesn't Fit My Car - Can I Return It?

Yes, you can return the kit for a full refund within 30 days of receipt if you find it doesn't fit your car. Just email our support staff to get an RMA # to return it for a full refund (less shipping).

Is there any kind of guarantee that comes with my HHO Kit?

Yes there is a full Five Year Warranty (800 Series) on our hho generators, and a 30 Day return policy on our kits and accessories.
