Kyocera CPR 12-15 User manual

The Cathodic Protection Unit (CP) is a specialized power converter which provides DC
current to metal pipelines, storage tanks, bridges, or other exposed equipment to cancel the
effects of natural chemical corrosion. The CP operates directly from storage batteries com-
mon to photovoltaic systems and is equipped with a low voltage shut-down feature to pre-
vent battery damage. It is suitable for use in systems of either positive or negative ground.
The Cathodic Protection Controller
is designed for trouble-free service
in all environments and includes
many special features which make
it easy to operate and maintain in
the field. Power consumption and
heat generation are minimized in
the CP since efficient solid
state circuitry is used instead of
ballast resistors typical of earlier
cathodic protection units. The
power circuit contains no moving
parts to wear out or break down.
Quality digital voltage and current
meters provide output monitoring which facilitates field adjustment. This is easily
performed by inserting a small screwdriver through the faceplate. Recalibration can
be performed in minutes without special tools or meter equipment.
Since corrosion protection systems normally operate in remote, unattended sites, they
should be protected from the common effects that make them fail such as: lightning
exposure, battery damage, and short-circuits. That's why every Kyocera Solar, Inc. CP
Unit includes lightning transient suppression, a low battery shut-down circuit and output
overload protection. Our dual transient protection network will suppress electrical spikes
and surges that normally damage field equipment. If the storage batteries become
discharged due to cloudy days or photovoltaic system failure, the CP Unit will automatically
shut down, preventing excessive discharge and protecting the battery from permanent
damage and costly replacement. Our built-in circuit-breaker prevents damage to the CP
and other components, should the output leads become shorted to one another. To help
reduce overall system cost, the CP includes
adjustable current and voltage outputs. Standard
photovoltaic modules can be used and the CP
output adjusted to the desired level.
Careful matching of the array to the DC converter
is not required. The CP Unit can provide:
1) Adjustable current output with fixed upper limit
on voltage output
OR
2) Adjustable voltage output with fixed upper
limit on current output.
