Today's Digital QC is the evolution of the original, ground-breaking ESP design which came to market in the 1980s. To this day it remains one of the best selling professional-grade surge protectors in the world - having sold millions of units. It offers very powerful protection but without the advanced monitoring and diagnostic capability of the Next Gen and enVision products.
Unlike standard surge protectors and power strips that use only metal oxide varistors (MOV), the Digital QC combines gas tubes, silicone avalanche diodes and metal oxide varistors into a patented circuit that does not degrade over time and provides very robust protection.
Like all ESP products, the Digital QC is proudly made in the USA with the highest quality components.
The Digital QC offers comprehensive power protection to safeguard equipment from the dangers associated with damaging surges, spikes, over voltage, EMI/RFI noise and wiring faults.
The Digital QC is available in a variety of voltage/amperage configurations. Many models also have Cat5e ETL verified network (RJ-45) and telephone line (RJ-11) surge protection to protect network interface circuits. The D5 series also includes power over Ethernet protection.
Note: plug and outlet types as well as phone/network connections will vary from model to model. The product images may not illustrate the exact configurations.
