The Notebook Protector uses a combination of conventional MOV, Ferrite Core and Capacitance technology for AC Mains and the DC telecommunications protection, with continuous “Cascade” Filtration on the AC Mains. Designed to protect sensitive electronic equipment from potentially damaging and dangerous high voltage spikes, RFI, EMI and transient voltage on the AC Mains electrical supply, by capturing and diverting electrical disturbances within the scope of the protection that commonly cause breakdown, poor performance, data loss and data corruption and long term cumulative damage or total destruction of unprotected connected equipment.
