State-of-the-Art Stock & Custom 3-Phase Auto-Transformer Manufacturer Offering Top Quality at Wholesale Prices 3-Phase Auto-Transformer A 3-Phase Auto-Transformer is hallmarked by having only one winding per phase.  This one winding has at least three taps, otherwise known as electrical connection points.  Connected to two taps are the load and the voltage source.  At the end of one winding is a tap that shares a common connection to both load and source.  Each tap corresponds to a different load or source.  Part of this one winding is also common to both primary and secondary circuits so there is no isolation between the two.  By its inherent design, a 3-Phase Auto-Transformer provides a compact and economical way to connect equipment to a different voltage or power supply.  3-Phase Auto-Transformers Applications, Benefits, and Options A 3-Phase Auto-Transformer is typically used for air conditioners, heating, and motor loads of industrial machinery.  Benefits and options to look for in a quality 3-Phase Auto-Transformer include the following: Can be utilized as a step up or step down transformer. Same functionality of an isolation transformer of the same voltage/KVA rating, without the isolation feature. Most units have the ability to hang on shelves, walls, h-columns, or to be floor mounted to meet many application requirements.  Larger sizes can be bracketed to the floor or mounted to a platform.  Most units are supplied with lifting lugs, removable front/back covers, and conduit knockouts for easy terminal access. Design features ensure proper ventilation with enclosure openings that correlate with cooling ducts in the coils. Ventilated steel enclosures suitable for most commercial and industrial applications with different NEMA ratings (2, 3R, 4, 4X, 12, etc.). Quiet operation when compared with equivalent isolation transformers. Less than 3% regulation. Class 220 insulation. UL listing. CSA certification. Copper winding options. Option for other primary and secondary voltages. Frequencies other than 60Hz. Temperature Rise (115c, 80c). Custom sizing (specific KVA). Neutral out to terminal. Open type (coil and core only). Special, protective, paint finishes. It is good to note that a 3-Phase Auto-Transformer (like a multiple-winding transformer) operates on time-varying magnetic fields and cannot be used directly on DC.
