Protection Where It Counts

Smart Power Systems offers our Guardian with TBF™ Technology for complete power protection for your business. The Guardian is a computer-grade filter and complete power filter solution for point of sale (POS) systems and peripherals. The Guardian provides clean power by eliminating spikes, surges, and line noise therefore reducing downtime and extending operating life. Whether you experience a minor or major power spike, our Guardian system will protect your business and keep your bottom line safe.

The full lineup of Smart Power Systems’  TBF™ Technology products that we offer can be found here.

Why Power Protection is Critical to System Performance

• Reduce unnecessary “no fault found” service calls due to power issues
• Eliminate downtime due to power related problems
• Protect your investments by reducing the need to repair or replace equipment and components

High voltage surges and low voltage spikes are causes of system failures and interruption leading to thousands of avoidable service calls annually on all types of electronic systems. The Guardian with TBF™ Technology delivers unparalleled performance for protection against minor and severe spikes and surges that comprise almost 90 percent of power related problems. Our Guardian products are rated 15/20 amps and protect systems requiring 120/240 volts.
