STFV Plus Series
|
Two Types of Protection in One Convenient Package
|
The Sola STFV Plus Series combines Active Tracking® filtration for low energy noise and surge suppression for high energy transients. It continuously tracks the input AC power line responding instantly into action upon detecting extraneous high frequency noise and high voltage transients caused by everyday events such as turning on machinery, motors, or equipment.
These devices are designed to meet UL 1283. STFV Plus attenuates or reduces the amplitude of high frequency noise to a maximum of 90dB that occurs in a range of 100 KHz to 50 MHz. STFV Plus provides the industry’s best IEEE C62.41 Category “A & B” Ringwave protection.
They are built to meet your unique requirements, and are available in hardwire, single phase configuration. They are designed for years of trouble free operation and require little or no operator intervention after installation.
Active Tracking® Filters Plus is one part of a total power
quality solution. They can be used alone or in conjunction with other Sola/Hevi-Duty products to solve more complex power quality problems.
