STFV Plus Series – Active Tracking® Filtering with Surge Protection
The SolaHD STFV Plus Series combines Active Tracking®
ltration for low energy noise and surge protection 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 for
Electromagnetic Interference Filters. 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 hardwired, single phase conguration. 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 SolaHD products to solve more complex power
quality problems.
