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 10 VAC, 1200 Amp is shown below.

P/N 17773A

Specification:

• Transformer: 12 KVA, 1 PH, 60 Hz, P/N 17773A
• Primary: 208/220/240, 58A
• Secondary: 10 VAC, 1200 Amps
• Open Core & Coil
• Dimensions:9″ H x 9″ W x 22″D
• Weight: 140 lbs
• Output bus bars are 4″ x 5″ x 3/8″ with one 9/16″ dia. Hole
• Force cooling may be required

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