CleanSweep® EMI Filters for Circuit Breaker/Power Entry Panels
Clean EMI-Free Power and Ground for Each Power Branch
Approval in progress
OnFILTER' new patented filters for circuit breaker panels offer a practical solution to providing EMI-free clean power and ground to your sensitive equipment: EMI filters protecting entire power branch that are installed right at the power entry/circuit breaker box. AC power filters provide EMI suppression in AC power and ground. Ground-only filters are also available for purpose-specific solution for grounding.
New product line includes EMI filters for majority of installations - filters for the entire power branch for both U.S./Canada types and DIN-rail models for the "rest of the world." Alternatively, if there is a electrically "noisy" piece of equipment that pollutes your entire power network with EMI, you can simply wire the filters "backward" blocking EMI from ever getting into your power network.
Power entry/circuit breaker panels have Neutral and Ground/Earth galvanically connected at the entrance. Control panels are placed "downstream" from the power entry and receive their power and ground from far away. Often, control panels have their own ground rods.
Another difference is in physical mount. U.S./Canada power entry panels require certain type of physical mount specific to these panels. DIN rail control panels prioritize the width of the DIN modules due to space deficit, while DIN rail circuit breaker panels require certain geometry to fit.
These differences require different approach in EMI filter design and construction. This is why OnFILTER offers different models of power line and ground EMI filters.
For control panel applications see our family of UL508A compliant EMI filters.
Power Entry vs. Control Panels: Why Different EMI Filters?
Why Do We Need Filters in Power Entry/Circuit Breaker Panels?
Because our power lines and ground are polluted with high-frequency noise - EMI - and this interferes with normal operation of sensitive electronics. Common misconception is that EMI comes only from your power company - this is far from reality. Majority of interference sources are right inside your house or facility. Motors in most appliances - refrigerators, HVAC, washers - are now pulse driven, a major source of EMI. LED lights work on pulses. Countless power adapters - switched mode power supplies - are also pulse-driven. Yet, our electronics gets more and more complex and more sensitive to noise.
OnFILTER' circuit breaker panel EMI filters block propagation of EMI from all sources - internal and external - to the power/ground branches that can be most affected by noise. Simple Installation, exceptional performance, and zero maintenance assure quiet clean power to your sensitive equipment. Alternatively, you can isolate known EMI sources by wiring a CleanSweep filter in that power branch in the opposite direction.
