The importance of acquiring proper UPS surge protector gear should no longer be considered an option. It should be considered a requirement.
Uninterruptible Power Supply equipment (UPS) have become very common today in business, schools, hospitals, homes, the military and more. They provide temporary battery backup power in case of outages.
In general, these valuable pieces of gear convert AC power to DC power. When a power interruption occurs, the UPS switches on and provides temporary backup power to the connected devices.
The most common types of UPS systems available today:
Standby systems are often found in small business's and homes and are the most affordable. They have small battery capacity and short battery-duration.
Line-Interactive units have an auto-transformer and 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.
Contrary to popular claims and apparent uses, a UPS is not actually a surge protector.
However, some, including the occasional professional, seem to think they are or at least appear to use them for that purpose. We don't recommend this.
A UPS may provide some form of partial or limited transient voltage protection through it's design. However, a properly designed surge protective device (SPD) that does not make.
ANSI/IEEE specified test results, the NEC and real world experience discourage the idea that a UPS provides quality surge protection.
Today, claiming an Uninterruptible Power Supply has "built-in" surge protection has become quite common.
The questions then become:
UPS/SPD combination designs are readily available today. However, the surge protection should be carefully evaluated. Most likely, the surge protection is for down-line equipment only. Protection can also be limited to a few select receptacles, leaving other equipment unprotected.
In our opinion, that's not the best UPS surge protector option.
It's important to be aware of what the definition of the claimed surge protection actually is for your down-line equipment.
Reminder... a UPS is a UPS... first and foremost. Not a surge protector...
In our opinion, relying on a UPS to provide true surge protection, is not the best protection option for down-line equipment. It's also not the best protection option for the UPS itself.
From our experience, following the recommendations of IEEE and FIPS provides the best UPS surge protector options. Installing a surge protector or TVSS unit upstream of the UPS is strongly recommended. Its also recommended to apply multiple levels of upstream protection where possible.
This layered approach protects down-line equipment and the entire UPS, its electronics, power supply and battery backup.
SPDs that provide Full Spectrum Protection are High Quality and High Performance. These type of SPDs are necessary to properly protect critical electronics within the UPS. Advanced, Frequency Responsive CircuitryTM design leads the industry.
Remember: A damaged UPS = No UPS = No Backup Power Supply.
These unique SPDs and SPD Options protect against multiple surge types, in all modes, found in commercial and industrial environments.
Not many SPDs provide protection against both Impulse and RingWave type surges. Even fewer do it in all modes. Our SPDs do.
When it comes to properly protecting Uninterruptible Power Supply systems from transient voltage, install Full Spectrum Protection from the leader in UPS surge protector design.
