STF Series Active Tracking Filters

Long Term Protection Against Damaging Low Voltage/High Frequency Noise.

The STF Series offers original active tracking technology to guard against, low voltage/high frequency energy transients. Electrical noise caused by everyday events—for example, turning on machinery, motors or equipment—can be very damaging over time. STF Active Tracking® Filters protect your equipment by continuously tracking the input AC power line and eliminating electrical noise using a low-pass or L-C filter consisting of a series of load dependent inductors, capacitors and resistors. Sized appropriately to handle the maximum current draw on the line, these filters are capable of absorbing a large bandwidth of noise.

STF filters are available in a wide variety of voltage and amperage ratings, for both single and three phase power. They are hardwired and designed for years of trouble free operation, requiring little or no user intervention after installation.
