UPS Surge Protector Gear Uninterruptible Power Supplies Are Not Your Best Surge Protector Option

It's important to acquire proper UPS surge protector gear.

Uniterruptible Power Supply equipment (UPS) have become very common today in business, schools and homes. They provide temporary battery backup power in case of outages.

In general...these valuable pieces of gear convert AC power to DC power and store it in batteries. When a power interruption occurs, the UPS switches and converts the battery power (DC) back to AC power.

This provides a continuous (uninterrupted) electrical supply to keep your equipment running for a predetermined amount of time.

The three most common types of ups systems available today are the Standby, Line-Interactive and Double Conversion units.

Standby systems are often found in small business's and homes and are the most affordable and most basic of the three.

Line-Interactive units are a step up from the Standby. These units provide an increased ability to tolerate brown outs while not tapping into the batteries reserve.

Double Conversion units are the most expensive and most advanced of the three. With these units the backup power is on/running continuously.

Uninterruptible Power Supply's Are Not Surge Protectors

Contrary to numerous claims...a UPS is NOT a surge protector. It may provide some form of limited (very limited) transient voltage protection through it's design...but a surge protector that does not make.

ANSI/IEEE surge testing results and real world experience differ from many UPS surge protection claims.

Our advice?

Don't treat it as one...because's NOT.'s called a UPS for a reason.

What About A UPS That Has Surge Protection Built In?

Good question.

There are some pretty nice UPS/surge combo units available on the market today for business and home. However, the surge protection option is likely protecting the down-line equipment only.

In our opinion...that's not the best UPS surge protector option.

  • What about the UPS itself? The sensitive electronics that operate the UPS are not protected.

  • What's protecting the UPS power supply and batteries?

You also should be aware of what the definition of the claimed surge protection actually is for your down-line equipment.

  • Are both normal and common modes protected?

  • Are the protection circuits shared or are they providing individually protected circuits?

  • Exactly what type and how much protection is provided?

  • How do you know if the surge protection is functioning or not?'s a UPS first and foremost...not a surge protector.

Relying on a UPS to provide true surge protection is not the best protection option available for down-line equipment... and certainly not for the UPS itself.

What Are The Best UPS Surge Protector Options?

As recommended by IEEE and FIPS...the best UPS surge protector option is to place a surge protector or TVSS unit upstream of the UPS. In some instances it's recommended to have two levels of upstream protection.

This protects the UPS electronics, power supply and battery backup.

Additionally...placement of a protection unit ahead of the AC power supply provides protection for the down-line equipment the UPS is supporting as well. back-up power supply...regardless of what type of UPS you are using.

If sensitive equipment is important enough to warrant a UPS system...then the UPS warrants being protected by a quality, correctly designed surge protection device.
