The CyberPower Home Office Surge Protector P600WSURC1 prevents spikes in energy caused by storms and electrical power surges from reaching your home office equipment such as laptops, small electronics, and chargers. The P600WSURC1 provides 1200 joules of protection and 6 AC outlets with a single wall tap plug. The two 2.1-Amp USB ports quickly charge USB-powered devices, including tablets. Features of the P600WSURC1 include automatic shutdown, an EMI/RFI noise filter, metal oxide varistor (MOV) technology, surge protection LED indicator (Protected), damage-resistant housing, and an anchoring screw. Surge Protection Diverts excess voltage away from sensitive electronic equipment during an AC power surge or power spike to prevent damage. Automatic Shutdown Protects connected electronics with the integrated circuit breaker which automatically switches off in the event of an overload that exceeds the model’s ability to suppress the signal. EMI/RFI Noise Filter Maintains clean power for connected equipment by filtering out electromagnetic and radio frequency interference to improve picture and sound quality. Metal Oxide Varistor (MOV) Technology Allows normal current to pass through the device, while diverting any surges/spikes through the ground circuit, to safeguard connected electronics and the surge suppressor. LED Indicator Illuminates to show surge protection status (Protected). Damage-Resistant Housing Ensures maximum durability and prolongs the life of the model.
