HPS Y006PKCB3L0U General Purpose Heavy Duty Autotransformer, 480Y to 600Y VAC, 380 to 480Y VAC Primary, 480Y to 600Y VAC/380 to 480Y VAC Secondary, 4.8/6 kVA Power Rating, 50/60 Hz, 3 Phase

HPS 3-phase autotransformers are available for applications where small voltage corrections are necessary in a distribution system. They are frequently used as an economical alternative to general purpose distribution isolation transformers to adjust the supply voltage to match specific load requirements when load isolation from the supply line is not required autotransformers can be used as either a step-up or step-down transformer.
