L/C Magnetics has considerable experience in building single phase and three phase high current transformers with a current rating from 500 amps to 3000 amps and with an output voltage ranging from 1 VAC to 16 VAC. One example of a 5 VAC, 800 Amp single phase transformer is shown below.

P/N 18433

Specification:

• Transformer: 4 KVA, 1 PH, 60 Hz, P/N 18433
• Primary: 220 VAC, 20 Amps
• Secondary: 5 VAC, 800 Amps
• Open Core & Coil
• Dimensions: 16″ H x 9″ W x 11″D
• Weight: 97 lbs approx.
• Output bus bars are 4″ x 5″ x 3/8″ with two holes
• Force cooling may be required

It is sometimes impractical to build a 3 PH high current transformer with a common core. It is easier to build 3 single phase units and integrate them together as a 3 PH system unit. Over the years L/C Magnetics has developed a significant amount of tooling to build high current transformers up to 3000 Amps.
