The APC C2 Wall Mount Power Filter is designed to fully protect your high performance wall-mounted display from damaging power surges, spikes and lightning. Isolated noise filter banks will eliminate EMI/RFI as a source of audio and video signal degradation. The LED status indicators on the C2 Power Filter provide proactive notification of changing power conditions including filtering, protection, overload, and wiring faults.A detachable two-foot power cord makes installation easier and provides flexibility to the user or installer, giving them the option to switch to a longer cord (sold separately) for particular installations.
