The Eclipse product line brings affordable surge protection to your PC, peripherals and other devices in the event of nearby lightning strikes, surges and spikes. In addition, Eclipse provides line noise reduction to minimize interference from the utility power. All Eclipse models include a load protected status LED to notify you in case of surge protection failure. On the EclipsePro and ProTel models, an audible alarm provides warning in combination with the LED. EclipsePro and ProTel models feature a ground OK LED to warn of building wiring faults which can potentially interfere with Eclipse's ability to arrest surges and spikes.
