CATHODIC PROTECTION CONTROLLERS
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 com­mon to photovoltaic systems and is equipped with a low voltage shut-down feature to pre­vent 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
reduce overall system cost, the CP includes adjustable current and voltage outputs. S t a n d a rd
