The Digital QC’s Multi-Stage surge protection and filtering technology allows the lowest amount of surge energy to reach connected equipment. Only a harmless remnant gets through to guarantee equipment receives stable power and functions properly. Its advanced power filter virtually eliminates normal and common mode electronic noise interference that can cause error codes, malfunction and unnecessary service calls. 

It also includes catastrophic over voltage shutdown protection to safeguard equipment from sustained over voltage events, Cat5e ETL verified network surge and telephone line protection, and wiring fault detection to ensure faultless installs.
