Farwest oil cooled cathodic protection rectifiers, manufactured by Universal Rectifiers, Inc., are recognized as industry leading in quality, workmanship and service life. Many years of field-proven service have led to the superior design of these rectifiers. Conservative equipment ratings, controlled manufacturing techniques, plus many extra features ensure long and trouble-free operation.

Typical cathodic protection applications for the oil cooled rectifier line include severe environmental conditions due to high humidity, dust, or other situations that would shorten the life of a standard air cooled rectifier.

Explosion proof models are used for Class 1, Group D locations and comply with U.L. Standard 698. While similar to the standard oil cooled rectifiers, the explosion proof units are fitted with special hazardous area fittings to eliminate possibility of an ignition source.

Universal Rectifier Ordering Guide

Configure an 8-position model number like OSOI 50-30 CBC
Positions from left to right are as follows:

Position #1: Model
O = Standard line, Oil immersed
Position #2: Type
S = Standard Rectifier (Manual taps) C = Constant Current (Reactor style) D = Constant Current (Solid state) E = Constant Voltage (Solid state)	P = Constant potential (solid state) I = Constant potential IR free (solid state) M = Multiple modes (solid state) V = Variac control
Position #3: Cooling
O = Oil Immersed	X = Oil immersed, explosion-proof
Position #4: Stack Type
I = Silicon (while other stack types are available, silicon is recommended)
Position #5: DC Volts
List Maximum DC Voltage Desired
Position #6: DC Amps
List Maximum DC Amperage Desired
Position #7: AC Input
A = 115/230, single-phase B = 230/460, single-phase C = 230/460 three-phase	D = 208, three-phase E = 115/480, single-phase F = Specify
Position #8: Special Features
A = Dual input wired for low voltage B = Dual input wired for high voltage C = AC and DC arrestors D = DC arrestor E = AC arrestor F = Filter choke G = Communications filter H = Meter switches J = Power On indicator light	K = DC failure warning light M = DC breaker or fuse R = 115 VAC convenience outlet N = Powder-coated cabinet over hot-dipped galvanized steel O = Aluminum or stainless steel cabinet P = Additional voltage control link bar taps S = Multiple circuits (qty.) Q = Other, specify
