LL2758: Lundahl Mains Transformer

Lundahl's LL2758 is a C-core mains transformer assembled with a small core air gap to compensate for any mains DC unbalance. The estimated power rating is 100VA, which can be increased with good cooling. The 2 x 250V secondaries are internally divided between the two coils. As a result, the transformer can be used with bridge or full wave rectifiers without the problem of asymmetric load. Magnetic stray is tiny if filament secondaries of the two coils and the 15V-0-15V winding are loaded symmetrically. 

Specifications:

  • 250VA power rating
  • The transformer primaries are connected in series for 210-250Vac and in parallel for 105-125Vac
