Islatrol IE Series Active Tracking Filters

Low-voltage noise is caused by everyday events such as turning on appliances or motors. Although less dramatic than high-voltage transients, the long-term effect of these frequent disturbances can be just as damaging. Islatrol Active Tracking Filters provide clean AC power by eliminating low-voltage noise. This design creates a foundation for a family of products that attenuate impulses that would normally go untouched by standard, parallel clamping devices.
