STFE Elite Series - Active Tracking® Filters with Surge Protection
The SolaHD STF Elite DIN Rail Mount Series combines
Active Tracking® technology with UL Listed surge
protection to protect against the full spectrum of voltage
transients and surges. 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 1449 3rd Edition,
UL 1283, cUL recognized, and CE. STFE attenuates or
reduces the amplitude of normal mode noise to a minimum
of 90dB that occurs in a frequency range of 100KHz to
50MHz, and of common mode noise to a minimum of 60dB
that occurs in a frequency range of 5MHz to 50MHz. STFE
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 DIN Rail mount, single phase
conguration. They are designed for years of trouble free
operation and require little or no operator intervention after
installation.
