The DPU4 Military-Grade Power Conditioner was designed and manufactured by Bantam Clean Power for our partner DPPS, LLC to satisfy the U.S. Government's Red Power and Black Power requirements.  This power conditioner has unbeatable surge suppression and anti-snooping technology on the grounding path.  It is a state-of-the-art product in every sense.

Why Should You Buy the DPU4?

  • This is military-grade (tough construction, domestic content, etc.)
  • Industry-leading surge suppression protection for ALL your critical devices
  • Red Power outlets feature voltage and current filtration on all three wires (line, neutral and ground)
  • Black Power outlets feature voltage filtration on Line and Neutral and voltage and current filtration on ground path
  • Filtration that enhances audio/video performance, including dynamic response power requirements
  • Consumes virtually no power (not transformer-based) to do its work
  • Four standard NEMA 5-15 receptacles, widely spaced to allow for power bricks and odd-shaped plugs
  • Designed, Engineered and Manufactured in the USA (Illinois and Wisconsin)
  • Perfect for your home, office, garage, shop or bunker.

The DPU4 has a unique power distribution network.  The black-colored pair of outlets supply 120 volts and 12 amps of power (1440 VA), supporting all types of linear and non-linear loads.  You can safely run motors, pumps, or electronics on these outlets with anti-snooping on the grounding path.  The orange pair of outlets supply 120 volts and 3 amps of power (360 VA) for critical data processing electronics that need Red Power anti-snooping protection and added filtration with wave shaping.  The red outlets are not intended for motors or other linear loads, but exclusively for electronic loads like computers, inkjet printers, LCD monitors, etc.

You can expect the same industry leading surge suppression capability as found in our Bantam Vanguard series.  These units are in use throughout the world in military bases protecting some of the most critical equipment.  They have proven themselves for over a decade.
