THE NEW POWER PROTECTION
FOR DIGITAL SYSTEMS
Ground noise must be eliminated
for your digital systems to
work properly. Every wall
outlet provides the power
to make your business
work... or fail. Each
day in offices
everywhere,
systems crash,
error codes and
lock-ups mysteriously
materialize, and re-boots
are par for the course.
The culprit is ground noise;
electricity that is not compatible
with the sophisticated circuitry
of digital and multi-function
equipment.
Service technicians will tell you that
ground noise is responsible for most logic
malfunctions. It causes more jams, mis-feeds,
and lock-ups than any other source. It cannot
be fixed by software upgrades or replacement
circuit boards.
How can you refine that “dirty power” and
eliminate damaging ground noise without
investing in an expensive isolation transformer?
The Digital QC is the only product that can
eliminate ground noise cost-effectively.
ESP’s Digital QC features a revolutionary detect
and correct system to eliminate ground noise.
Our two-step process first detects the power line
and verifies that it is properly wired. Then, it
corrects ground noise levels by engaging the
patented Zero Voltage Ground circuit.
ESP’s Patented Zero Voltage
Ground Technology...
• Increases Up-Time by upgrading
to computer-level power
• Protects Data by eliminating
harmful ground noise
• Extends Equipment Life by
protecting your digital equipment
from dirty power
• Boosts Reliability by removing the
biggest cause of jams, mis-feeds and
lock-ups
• Lowers Ownership Costs by
safe-guarding sensitive circuitry
and Network and Internet/Modem
connections
• Exclusive Ground Window, a
single point grounding inside the
Digital QC eliminates ground loop
window potential.
• Meets the ANSI/IEEE 62.41
National “No Upset” Threshold
Standard.
Comes With Our Catastrophic
Equipment Protection Guarantee
promising that if your electronic
equipment is damaged due to a severe
power surge or lightning hit, ESP
warranties the repair or replacement
of your equipment at no cost to you...
a level of protection superior to your
present warranty or service contract.
The Digital QC provides clean power to your
business, at a fraction of the cost of an isolation
transformer. By eliminating ground noise
Digital QC safeguards your sensitive equipment,
boosting productivity and protecting revenues.
™
Zero Voltage Ground is a high capacitance neutral to ground circuit. Now, combined with
the Digital QC’s patented power scrubbing circuit and communications ground window,
you have the ultimate in real power protection for digital equipment.
The business office has moved into the digital realm.
Isn’t it time to move power protection there too?

REAL POWER PROTECTION
BREAKTHROUGH TECHNOLOGY ELIMINATES GROUND NOISE
About Our “Ground”breaking Technology... According to OEM specifications,
anything over half a volt noise on ground compromises digital equipment peak performance;
it’s unacceptable. Equipment protected by ESP’s Digital QC technology have virtually no
noise on ground. Sensitive microprocessors— computers, digital phone systems, Internet/
Modem and Network connections—are protected; the OEM spec is met. And at a fraction
of the cost of similar power protection systems.
Digital QC System Configurations - As simple as 1-2-3. Begin with the Digital QC
and select one option from each of the following three columns:
Voltage
Amperage
Network & Modem
120 or 208/240 Volts
15 or 20 Amps
Yes or No
For example: Digital QC +120 Volts + 20 Amps + Network/Modem
Bonus Configuration: For workstations, desktop computers and file servers, just
specify the Digital QC Workstation. It is a 120 Volt, 15 Amps with Network &
Modem, patch cords and an On/Off switch.

completely eliminate GROUND NOISE. The noise that you can see on the ground line is
eliminated by the Digital QC. Noise that will disrupt the operation of a Micro Processor,
the brains of every Digital System. ESP’s patented Zero Voltage Ground circuit, after
detecting the correct wiring and making sure there aren’t any ground or neutral faults,
switches on the Zero Voltage Ground Circuit.
