Lundahl High power general purpose transformer, LL2410

Universal Power Line Transformer LL2410

LL2410 is a high inductance line transformer for connecting PA system loudspeakers to power lines. The transformer is highly sectioned, with harmonically sized sections, which results in a minimum leakage inductance. The twelve windings can be combined in a number of ways, but symmetry between coil 1 and coil 2 is essential for good performance.

The transformer has a special audio C-core of our own production.
