Kyocera CPR 12-15 Datasheet

The Cathodic Protection Unit (CP) is a specialized power converter which provides DC
c u rrent to metal pipelines, storage tanks, bridges, or other exposed equipment to cancel the
e ffects 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 gro u n d .
The Cathodic Protection Contro l l e r
is designed for tro u b l e - f ree serv i c e
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 circ u i t ry is used instead of
ballast resistors typical of earlier
cathodic protection units. T h e
power circuit contains no moving
p a rts to wear out or break down.
Quality digital voltage and curre n t
meters provide output monitoring which facilitates field adjustment. This is easily
p e rf o rmed by inserting a small screwdriver through the faceplate. Recalibration can
be perf o rmed 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
e x p o s u re, battery damage, and short - c i rc u i t s. That's why every Kyocera Solar, Inc. CP
Unit includes lightning transient suppression, a low battery shut-down circuit and output
overload pro t e c t i o n. Our dual transient protection network will suppress electrical spikes
and surges that normally damage field equipment. If the storage batteries become
d i s c h a rged due to cloudy days or photovoltaic system failure, the CP Unit will automatically
shut down, preventing excessive discharge and protecting the battery from perm a n e n t
damage and costly re p l a c e m e n t. Our built-in circ u i t - b reaker prevents damage to the CP
and other components, should the output leads become shorted to one another. To help
