The demand for lightweight components is well known in the aerospace industry, but now this demand is reaching off-shore applications. The LW series are custom designed power and isolation transformers for 400 Hz frequency operation up to 600 Vac onboard seaborne and other marine applications. Compared to conventional C-core transformer designs, the LW series weighs about 50% less with its Copper Clad Aluminum (CCA) wire windings and low profile toroidal cores using 4 mil thick grain oriented silicon steel.
The custom designed power and isolation transformers are available up to 10 KVA power rating for single phase or 30 KVA for three-phase systems. As is the case with all toroidal core transformers, lower no-load losses, quiet operation and no hot spots are other benefits. With in-house core production dimensions of OD and height are flexible to suit the customer’s requirements. For three-phase systems, each phase is served by a separate transformer allowing better weight distribution inside low profile cabinets as an alternative to stacking the transformers on top of each other or vertically side by side.
Weight examples of single-phase transformers range from 4.5 lb for 1000 VA to 28 lb for 10 KVA and for three phase systems from 13.5 lb for 3 KVA to 84 lb for 30 KVA.
