STFE Elite Series combines sinewave tracking technology with surge protection to protect against the full spectrum of voltage transients and surges. These DIN rail mounted devices protect your equipment by continuously tracking AC power input and responding to high voltage transients and high frequency noise. They are available as hardwired, single phase units in a wide range of amperage ratings and designed for years of trouble free operation.

The STFE Series attenuates or reduces the amplitude of normal mode noise to a minimum of -90 dB that occurs in a frequency range of 100 kHz to 50 MHz, and common mode noise to a minimum of 60 dB that occurs in a frequency range of 5 MHz to 50 MHz. STFE provides the industry’s best IEEE C62.41 Category A and B Ringwave protection.

The STFE Series is built to meet your unique requirements, and are available in hardwired DIN Rail mount, single phase configuration. They are designed for years of trouble free operation and require little or no operator intervention after installation.
