L/C Magnetics are specialist Three Phase Custom Designed Buck-Boost Transformers. Buck-boost Transformers are very useful in buck or boost applications of voltages and currents and are not a replacement for all isolation transformer requirements. We can provide buck-boost transformers as an open core and coil unit or enclosed in an indoor enclosure with corrosion resistant powder coating. We can also install the transformer in a NEMA 4X enclosure or a stainless steel enclosure. L/C Magnetics can manufacture single phase or three phase buck-boost transformers up to 1000 KVA power rating. All of our Custom designed Three Phase Buck Boost transformers are built to order. We have the proper tooling and winding machines to give you a fast turnaround.
