Single phase, general purpose transformers may be used to achieve a wide variety of nonstandard voltage combinations. These combinations are achieved by connecting two identical, 240/480 volt primary, 120x 240 volt secondary, and single phase transformers into three phase, autotransformer banks - much like the buck-boost configurations. Electrostatic shield between primary and secondary windings provides cleaner output voltage and helps to reduce spikes and transients.

• Aluminum windings connect to bus bar style terminations equipped with NEMA standard holes for compression style or ring terminals.
• UL Class 220C insulation system with a 150C temperature rise at full load and a maximum ambient of 40C.
• NEMA Type 3R, ventilated, cabinet style, floor mount enclosure suitable for indoor or outdoor use. Ground studs provided for bonding compatibility with both metallic and nonmetallic conduit.
• Core and coil and nonstandard designs.
