  • Overview +

    The Digital QC’s Multi-Stage surge suppression and power filtration 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 filtration system virtually eliminates normal and common mode electronic noise interference that can cause error codes, malfunction and unnecessary service calls.

    ESP’s technology incorporates a series combination of varistors and a three-terminal gas arrestor that suppresses both normal and common mode surge energy. It safeguards equipment from harmful surges, spikes, high-speed transients, and electronic noise events that can cause error codes, misfeeds, paper jams, color quality degradation, downtime, and customer dissatisfaction.

    Keep your mid-level office equipment and business up and running with the Digital QC.
