HPS offers 3-phase auto transformers for applications where voltage isolation is not necessary, but some level of voltage adjustment is required. They are frequently used as an economical alternative to 3-phase general purpose distribution transformers to adjust the supply voltage to match specific load requirements when load isolation from the supply line is not required.

HPS Y Series Autotransformer Auto Transformer, Convection Cooled, 600Y/480Y VAC, 480Y/380Y VAC Primary, 600Y/480Y VAC, 480Y/380Y VAC Secondary, 75 kVA Power, 50/60 Hz Frequency, 3 ph, Neutral Connection, Floor Mounting, 200/220 deg C Insulation, NEMA 3R Enclosure, 30/40 deg C, 20.2 in L x 19.38 in W x 21.5 in H Dimensions
