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.
The STFE Series 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 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.
