Clamp voltage is a measure of when a MOV based surge technology will react in the presence of elevated voltage.  For example, in the standard 120 Volt circuit, a clamp voltage of 360 volts means the MOV will start reacting at 360 volts, so at least 240 additional volts have gone into the (supposedly) protected electronics before the MOV starts to react.  In addition, MOVs react in milliseconds, however surges are 1,000 times faster microsecond events. Once activated at 360 volts, MOVs then oscillate very rapidly between clamped and unclamped (in milliseconds) until the voltage drops below 360 permanently.  Microsecond surge energy is getting through before and during MOV oscillation.   All the while, the MOVs are wearing out. 

MOVs are sacrificial, so they degrade and stop working after an unpublished and uncertain number of surge events.  It is likely half the MOV based surge protectors in use today have degraded to the point where they are essentially unprotected power strips.

The inductors in the patented Bantam circuit are always energized and operate bi-directionally along line, neutraland ground.  The magnetic field impedance responds instantly to the surge, expanding the magnetic reservoir to reduce and absorb the surge energy. Bantam is a wave-shaping conditioning technology that reduces the amplitude and expands the duration of a surge event to dissipate the energy.  There is virtually no delay in reaction or electronics protection because the technology doesn’t react afterthe surge arrives, it is altering the dynamics of the surge in microsecond real-time.

Surge and Transient Protection


The Bantam circuit was tested at 6,000 volts, 3,000 amps, and absorbed this energy over 1,800 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

Energy Surges and spikes usually originate outside the wiring in your home or business. They are random, and represent less than 20% of the power anomalies equipment will experience. Lightning is an extreme example of an outside energy surge, but power spikes and surges caused by the starting and stopping of heavy equipment, motors, elevators, air conditioners, and spa pumps originating in adjacent facilities are more common examples. 

The technology in the Bantam will absorb these dangerous energy surges on Line, Neutral andGround, then release the energy back into the circuit as safe usable energy.  The circuit does not divert the energy pollution to ground where it can interfere with digital coding. (One electrical attempt at providing cleaner grounds is to have “isolated grounds” installed by an electrician at considerable expense – only to find that these clean grounds are perfect antennae for noise!).

Bantam is a wave-shaping device, reducing the amplitude and stretching the wavelength of all non-fundamental frequencies.  The technology is responsive to amperage and can be scaled to any energy level.  Bantam technology is never sleeping, working at surge inception so there is zerodelay in protection.  Bantam does not affect 60Hz frequencies, but will increase filtering effectiveness as higher frequencies join the 60-cycle signal, absorbing unwanted energy and ensuring a clean unpolluted 60-cycle sine wave.  Short duration, high-energy pulses like lightning, spike, surges, arc flash, and conducted EMP (not air bursts) are extreme energy events the Bantam circuit can delay and absorb, protecting the connected device. 

MOV based products advertise their effectiveness using Joules as a proxy for how much energy can be dumped to ground before MOV failure. Joules of energy tolerance before failure is not a very useful measure because it only tells the consumer how much energy a MOV suppressor can tolerate, not how much energy the MOV let through to the protected device. The point of suppression protection is to keep harmful energy away from devices.  

A better measure is how much energy as measured in Surge Destructive Energy got through the SPD to the protected device, the Surge Residual %.

If you calculate the total possible Surge Destructive Energy of a 6,000 volt, 3,000 amp surge at 10 microseconds the result is 180,000,000 total Destructive Units. A true measure is to compare total possible SDE to the SDE that gets through the Surge Protector to the protected device. 

For a 10 microsecond burst, a typical MOV-based suppressor will have a Surge Residual of about 7% of the total SDE.  The other 93% was diverted to ground.  When the MOV degrades and fail, so does the surge protector.

The Bantam will allow less than 0.5% of the total of the Surge Destructive Energy to reach the protected device. The remaining 99.8% of the damaging energy is being absorbed and re-distributed as clean power, and is not diverted to ground. The Bantam has been shown to mitigate over 1800 such events in 24 hours without damaging the protected device, and with no loss of Bantam effectiveness. This is how you should measure protection. 

Because Bantam does not rely on MOVs, it has no Joules limitation and zero reaction time.  The always-active Bantam circuit senses a surge, delays and extends the energy wave absorbing the damaging energy, (does not dump to ground), and returns safe energy to the power system.
