Product Description

Note: This product is currently a non-stock item. It typically can take over 2 weeks to receive your unit after purchase.

This 120Amp Boost Regulator is just like our Super Booster, except it can handle 120Amps at 50% duty cycle. It will allow you to boost and regulate DC voltages up to 15+ Volts, with an input as low as 9Volts.

It comes with 2AWG Zipcord pigtails that are 2 feet in length. It also has two thermally controlled cooling fans.

It can be run fulltime or boost just when talking with the RF Enable circuit.


A Piezo Low Voltage Alarm can be added to this unit.  Just click the option when adding to shopping cart.

Our Remote Meter Panel is compatible and can be used with this unit.

Your new Boost Regulator will allow you to:

• Maintain any output voltage greater than battery voltage up to 15+ volts!

• Keep Battery voltage present at the output with the supply turned off! 1

• Boost voltages up to an 80 Amps load. Rated for 50% duty cycle at 80Amps.

• Protect your battery with a low voltage lockout feature. 2


1 Battery voltage less one Schottky diode voltage drop.

2 Low Battery voltages set to 9, 10, or 11 volts. Note: The unit does not disconnect your load from the battery.

  1. Does exactically what it is designed to do! 5 Star Review

    Posted by on 13th Mar 2015

    Tim worked with me to get this in a short time. Installed in my 2004 F-150 to help keep up with my HF and Ten Tec Hercules II amplifier. Under full load with 500 watts output FM the output voltage does not sag at all. Running SSB is a dream with 14.2 VDC at the amplifier. I searched on receive and can find NO RFI products. I am running a 145 Amp alternator that would sag down to about 13.1 or lower before the Booster install. Just using a standard battery. So Now I have full output for my mobile installation.
