The Universal "SW" Series rectifier is analternate to the standard line. The "SW" rectifierfeatures lift-off design case which permitsunlimited accessibility for routine maintenanceand inspection. Simplified design reducesmanufacturing costs which provides aneconomical rectifier ideally suited to mostapplications. Rectifier components mounted on11 gauge chassis panel for easy removal.

EXAMPLE
This chart is useful forcalculating A.C. line current.Multiply D.C. volts times the D.C.amperes to obtain the figuresacross the bottom of the chartand follow a vertical line up untilthe A.C. voltage and phaseselected is intersected. Readacross the chart for the A.C. linecurrent.
Example: A 24 volt 100 amp rectifier operating on 230 volts A.C.three phase will draw 8 A.C.Amperes.
For units less than 10';000 D.C.watts, divide all figures by 10.
