Yes.  Isolated or dedicated grounds are most often installed as a direct path to earth ground via a wire that ensures the ground is not contaminated by other devices connected to the home or business wiring.  Since computers and servers use the ground as a zero voltage reference, not having energy pollution in the form of spikes and transients on ground is important.  The patented Bantam circuit filters all three wires, Line, Neutral, and Ground, so that unwanted energy on any of the three wires, from any power pollution source, are filtered.  Plugging your computer or server into a Bantam will provide a pollution free ground, and is much less expensive than having an electrician install an isolated ground wire and conduit back to the electrical panel and earth ground.


Bantam Revolutionary Technology

The technology in the Bantam series of power filter/surge protectors developed by Leveler was awarded US and International patents because of its novel concept and design.  This overview will explain this technology, its value, and provide links to additional analysis, third party evaluations, and user testimonials.

The patents were awarded to a revolutionary circuit that protects sensitive electronics from power pollution in the form of surge, spikes, swells, transients, ripples, and harmonics, while providing power factor correction; all in a surprisingly small package…

Surge and Transient Protection

The Bantam circuit was tested at 6000 volts, 3000 amps, and absorbed this energy over 1800 times in 24 hours without damage to protected electronics or loss of Bantam effectiveness.

• Protection from Lightning, Certified to UL1449, 3rd Edition

            • No delay in protection, Bantam is working at the inception of the surge.

            • Extreme Joules of energy will be delayed and absorbed.

• No power pollution is dumped to ground.

• The Bantam technology will delay Arc Flash Energy long enough to allow breakers to trip.

• Bantam does not use capacitors for surge diversion, unlike typical Series Mode suppressors.

• Bantam products using the Patented Circuit have a Lifetime Warranty…

The same Bantam circuit described on previous pages will also Condition, Attenuate, and Filter non-fundamental frequencies starting above 60Hz and going up to 1Ghz as reported by National Test Labs (NTS) in Huntsville AL and Plano TX.

   • The Bantam filter technology is bi-directional

   • Bantam provides up to 20dB of bi-directional common mode insertion loss up to 30MHz.   

   • Bantam provides up to 30dB of bi-directional Differential mode insertion loss up to 30MHz.

   • Bantam provides up to 15dB of bi-directional Current Harmonic Suppression up to 10KHz.

   • Bantam’s 20dB suppression provides significant EMI/RFI suppression from 1MHz to 20MHz.

70% of power pollution is persistent and the result of power pollution from other electronics that are either on local shared home or business wall power circuits, or from wireless devices….

Filtering and Protecting Ground

The same Bantam circuit described above filters Ground in addition to Line and Neutral, ensuring a pollution free ground important to sensitive electronics and audio equipment.

     • Bantam helps maintain a stable ground reference important to digital coding.

     • Eliminates the need for expensive Isolated or Dedicated Grounds for computers.

     • Bantam will block hackers from using ground signal infiltration also known as Power Line Exploit

Computers use a “stable ground reference” to distinguish ones from zeros in digital coding.  Digital circuits compare the presumed zero voltage on the ground as a reference to differentiate the positive volts on line or neutral.  As little as 0.1 volts (100mV) can pollute this ground reference. If a surge or spike of energy over 0.1V is traveling along the ground at the instant the code checks for a reference, 1s or 0s can be miss-interpreted.  The more polluted power that dwells on the ground, the larger the chance for a code error…

Improved Power Factor

The same Bantam circuit described above will also improve capacitive power factor by up to 30%, depending on the initial power factor level. 

 Bantam will improve Power Factory by up to 30%, saving power. 

 Improved Power Factor will reduce stress on components and extend their life.

Power Factor is a term used to describe the efficiency of the sine wave power signal utilized by a device. Suffice it to say the closer the power factor is to 1, the more efficient the use of the power…


Surge Residual is How Surge Protection Should be Measured

Revolutionary patented circuit in Bantam products will absorb more than 99% of surge energy, allowing less than 1% of the damaging surge energy to reach your device. Surge Residual is how to measure a surge protector’s value.

Underwriter’s Laboratory compared surge residual in surge protectors and found inexpensive consumer surge protectors allow between 10 and 20 times more damaging energy to reach the protected device than the Bantam did. The Bantam Technology met the 1% Surge Energy Residual threshold easily, allowing only 0.2% energy through, suppressing 99.8% of the damaging Surge Energy.

What is PLE and how can Bantam Prevent it?

Power Line Exploit (PLE) is relatively new but a growing Hacker threat. An IEEE paper in December of 2019 confirmed PLE exists and is a threat to IT security. The transistor switching pulses and the power supply switching pulses generated by IT equipment create signals that emanate from power traces to the ground trace and wire via inductive coupling or inducement, the principle behind radio transmission. 

Power Line Exploit is sensing and interrupting these electrical magnetic impulses, that are very low in power and very high in frequency, on the ground wire exiting IT equipment. PLE is focused on current, not voltage. Exploiting voltage data required touching or connecting too wires. But to exploit data traveling with the current, the Hacker collection device does not need to touch the wire, it only needs to be close enough to detect the electrical magnetic field emanating from the wire…
