Description

The “Well Casing” Air-Cooled Rectifier line is a limited output version of the standard line of manual set Cathodic Protection rectifiers, aimed specifically for well casing market.

 

 

 

 

 

 

Combining a lighter gauge enclosure with a chassis pan method of component layout results in a cost-effective rectifier. Incoming AC power is stepped down, isolated and rectified to a controlled DC output. Input-overload and short-circuit protection is provided by magnetic-trip breakers; output protection by means of one-time fuses in the transformer secondary. Primary AC/DC surge protection and secondary surge protection is provided by disk-style M.O.V’s. Output control using 20-steps of tap adjustment, gives ample control to output settings. Separate ammeter, with built-in shunt and voltmeter, are supplied standard. No meter switches are used. The “Well Casing” line of rectifiers has optional extra circuits (maximum 2) available for multiple well casings or flow line requirements.
