CorrosionManagement | March/April 2012FOCUSONcathodic protection & monitoringFOCUSONCONSULTANTSRectifier TechnologiesPRODUCT LAUNCH BY RECTIFIER TECHNOLOGIES (UK) LTDRectifier Technologies, a leading Designerand Manufacturer of Impressed CurrentCathodic Protection Power Supplies utilizinghigh efficiency Switch Mode technology,has pleasure in releasing the latest additionto its family of Rectifiers.The RTD CP500 Power Supply is a SwitchedMode Supply (SMR) module designed toprovide up to 500 watts of output power. Itis designed to be used in conjunction withcorrosion protection equipment and caninterface with a wide range of CP systems.The Module can be used as a stand aloneunit or as part of a bank of modules forgreater power. The CP500 is small andefficient and has a built in supervisorysystem which allows it to interface withexternal communications.The Input is Universal, single phase, 85 –264v AC with efficiency greater than 90%and power factor better than 98% with ACripple on the DC line less than 1% at fullload. It can operate in constant voltage,constant current or automatic modes. It hasinbuilt Interrupt facilities and USB interfacefor communications link to a PC and aninterface for GPS option. Facility is providedfor connection to a reference cell or externalcell module.Operating Temperature Range is -20C to50C.Used in conjunction with this Rectifier is aProgrammer Module designed for initial setup via a CAN BUS interface. The Programmercan be used as a removable module, forsystem inspection only, or as a fixed modulefor use with a backplane. When fitted to abackplane the programmer can be used forcontinuous system monitoring and control.It features an alphanumeric display and twosimple user controls.Amongst other functions the Programmer isutilised to set Interrupter timings and GPSSynchronization, zone control and remotecomms options. Once the parameters havebeen set they are loaded into the rectifierand will remain as fixed settings unlessreprogrammed.Setting the Programmer is simple. The rotaryencoder scrolls round the internal modesallowing the operator to easily update anysystem variables. The digital alphanumericdisplay ensures that user informationcan be read accurately, even in low lightconditions.The mechanical format can be Stand aloneRectifier (Minimum format) - Stand alonewith full Side plane mounting Programmer(single pluggable connection betweenRectifier and Programmer) – Stand alonewith parallel modules (single programmer,offering current sharing between modules)– Magazine system with parallel modules(single programmer, offering current sharingbetween modules).All options can be supplied eitherWall or Cabinet mounted.For more information contact: Rectifier Technologies Ltd., Sturmer Road, Haverhill, Suffolk, CB9 7UU, England.T: +44 (0) 1440 706777 F: +44 (0) 1440 762810 www.rtuk.co.uk12
