Conditioned Power Center
11
Welcome to the world of conditioned power. Electrical power users from around the world benefit from the use of
clean, quality power. That's why we developed the Conditioned Power Center (CPC). The CPC Series is a low-
impedance power conditioner that provides high peak-load capability. You'll find that we've engineered these
products to provide features not readily available as standard equipment on other three-phase power line
conditioning products. The CPC series of products provide the functionality and flexibility that your business
needs in a power quality solution-both now and in the future.
3.1 Product Purpose
The CPC is designed to eliminate high-frequency noise and high-voltage impulses (also known as spikes or
surges) from the AC power that runs your electronic equipment. The power conditioner installs between the
power source and the critical load. And because it is a three-phase device, the CPC provides protection for all
transformer phases that power a large system. Sophisticated electronic systems contribute to the profitability of
your business, and clean power is an essential element in their reliable operation. Each electronic system
responds to power-quality problems differently, but properly protected systems benefit in a variety of ways. These
benefits include fewer hardware failures, fewer "no problem found" service calls, less system downtime, higher
manufacturing yield, better image quality and longer equipment life.
The CPC power conditioning series incorporates these three important power quality elements:
1. A low-impedance isolation transformer - The transformer is the "heart" of the power conditioning system. It
provides unequaled protection against common mode (neutral to ground) disturbances and voltages. In addition,
it provides all the criteria necessary to meet National Electrical Code 250-5d requirements for a "separately
derived power source." The isolation transformer can be specified to accommodate the variety of electrical supply
voltages and frequencies that are encountered throughout the world.
2. A low pass filter - The filter is responsible for removing normal mode (phase to neutral and phase to phase)
noise components from the electrical power. These power disturbances are the ones that are caused by your
system's "electrical neighbors" (i.e. elevators, copy machines, motors, HVAC equipment and even other
computer systems).
3. A surge diverter - The surge diverter is part of the input (primary) circuit of the isolation transformer. This
ensures that any voltage impulses generated within the facility (our outside of it due to occurrences like lightning
and utility activities) do not interfere with the connected system. Although the surge diverter is designed to
handle substantial energies, catastrophic events may occur, which damage one or more of the circuit’s protective
elements. If such damage occurs, one or more of the TVSS Fault LEDs on the power conditioner’s front panel
will illuminate. Consult Section 8.1.3 for instructions on how to proceed if a TVSS Fault LED illuminates.
