The SolaHD STF Series offers the original active tracking technology to guard against commonly occurring but very damaging lower-energy transients. Offering excellent noise reduction, the filter continuously tracks the input AC power line and responds instantly upon detecting extraneous high-frequency noise.

The STF Series eliminates low voltage/high frequency noise via a low-pass or L-C filter. These filters are used for low-energy, high-frequency noise reduction and consist of a series of inductors, capacitors and resistors. STFs are load-dependent, which means that the series inductors located on each phase and neutral conductors are sized to handle the maximum current draw on the line. These inductors, together with the capacitors and resistors, form a circuit capable of absorbing a large bandwidth of noise.

The SolaHD 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 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. The STFV Plus series 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. It provides the industry's best IEEE C62.41 Category "A & B" Ringwave protection.

The Sola Hevi Duty STFE 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, 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.
