Mini-Distributed Gap (Mini-D7)

The Mini Distributed Gap (Mini-D7) core belongs in the suite of distributed face cores but is used for quick assembly of small voltage transformers less than 3kVa. lt is a series of laminations with very small overlapping steps clustered towards one end of the core leg. The number of steps increases with build up, which means the packets of laminations becomes bulkier as the build up increases. The cascade of cuts diverges to produce a distributed gap face with no two cut faces sitting adjacent to each other between lamination stacks. The corners are selectable between 45 and 90 degree and the inner corner radius is adjustable.
Voltage transformers smaller than 3kVA.
Ease of assembly, low loss face.
