The Right High Quality Power Surge Protector

We provide High Quality Data-Line, Telecom-Line, Custom Design and Power Surge Protector equipment. These devices are designed for the industrial, commercial, solar, wind, military and residential markets.

Advanced Products & Systems LLC transient voltage surge suppressor products are not the average "off the shelf" mass-produced commodity type equipment. The Advantage® Series, SpecPro and Surge BarrierTM SPD designs do more for sensitive electronics and electrical systems than just mitigate external and standard impulse surge activity.

SpecPro and Advantage® Series power surge protectors are... often imitated... but rarely duplicated...

High Quality Power Surge Protector Design

Optimal Response Circuitry

Defines the SSI overall SPD approach of applying state of the art components with innovative, hybrid networks, custom circuit boards and patented fusing methodology. Combined to work together efficiently, effectively and reliably, Optimal Response CircuitryTM provides the best surge protector designs available today:

  • Discrete True All-Mode Protection
  • Voltage Responsive CircuitryTM
  • Frequency Responsive CircuitryTM
  • Patented ElectroChemical Encapsulation
  • Component Level Fusing and Patented Internal Over-Current Fusing

Discrete True All-Mode Protection

High Performance SPDs employ a Discrete True All-Mode Protection methodology. This unique design provides independent protection elements for all electrical pathways (modes) in a given electrical system scenario.

Why This Design Provides Superior Protection:

  • There are no sharing of protection components to protect a pathway in our SPD. If there is an electrical pathway in the system, its protected with individual components. Unlike many competing SPDs, Advantage® Series units do not use four mode or seven mode designs to protect ten. If there are ten modes in a system, all ten modes are protected directly.
  • Designs don't skip protecting a pathway altogether claiming surges don't occur in that mode. Surges can occur in any mode. This has been proven in the field and can be found stated in electrical industry publications.
  • Voltage Equalization. Bonding all pathways (modes) to the same potential (SPD design) creates voltage equalization during a surge event. This advanced design mitigates power surges AND equalizes the voltage during the surge event.
  • Delivers industry best Let-Through Voltage (MLV) performance.

Voltage Responsive Circuitry™

Designed to mitigate repetitive high-energy impulse transients generated by lightning, power system faults and load switching. This multi-level hybrid network design provides the brute strength and durability needed to handle repetitive high amplitude transients.

  • This technology is standard on all units.
  • 20kA - 900kA Ratings

Frequency Responsive Circuitry™

This Advanced Technology can be implemented with Voltage Responsive CircuitryTM arrangements. Frequency Responsive CircuitryTM is specifically designed to protect critical electronic circuits and microprocessors.

Provides Electronics with Full Spectrum ProtectionTM:

  • Frequency Responsive Circuitry™ technology employs a multi-stage hybrid design blending SSI's Optimal Response Circuitry™ dynamics with Advanced Frequency Responsive Circuitry™ Performance.
  • The resulting hybrid design suppresses internally generated RingWave transients down to harmless levels, yet is still capable of handling thousands of repetitive high-energy impulse surges. This combination provides a level of durability and performance that is unmatched.
  • Without Frequency Responsive Circuitry™ sensitive electronics are susceptible to fast rise, oscilating and repetitive RingWave transients other technologies fail to address effectively.
  • Frequency Responsive Circuitry™ is not an EMI/RFI Filter nor partial SineWave Tracking technology. SSI's Frequency Responsive Circuitry™ delivers a superior level of protection.

ElectroChemical Circuit Encapsulation

All SSI power surge protector devices utilize high dielectric circuit encapsulation. This technology is used in high-end, mil-speck applications. The encapsulation enhances the Let-through voltage (MLV) performance by reducing the overall size of the device. SPD durability, longevity and reliability is improved by increasing component and circuit integrity.

High Quality Options

Many SPD's in the marketplace are a one-size-fits-all type device. Essentially, the same device design is used when different types of protection technology or additional device options would provide more effective solutions.

Examples when different protection technologies are warranted:

  • Multiple Surge Type Environments
  • Installation Scenarios
  • Connection Methods
  • Fusing Applications 
  • kA Potentials

We provide Quality Options to address these different scenarios. This provides the best protection designs available.


Because of the commitment to provide a superior SPD that is built to last, SSI SPDs are supported with the finest warranty available. There are no outlandish claims made. As such, there are no fine print "nuggets" or "grey areas" that many other product warranties contain. This warranty couldn't be supported if the SPDs didn't perform.

All high performance units are backed with a 15 Year or Industry Leading 25 Year "No Hassle" Warranty. These Warranties even include damage to SPDs caused by lightning strikes.
