LL2749: Lundahl Mains Transformer
Click to Zoom
The LL2749 C-core mains transformer has four secondary windings of 20V, 2A. The core is assembled with a small air gap to compensate for any mains DC unbalance. The estimated power rating is 250 VA, which can be increased with good cooling. Magnetic stray is tiny if the secondaries of the two coils are loaded identically, as suggested below.
Specifications:
- 250VA power rating
- The transformer primaries are connected in series for 210-250Vac and in parallel for 105-125Vac
- Secondary winding 1: 20V, 2A
- Secondary winding 2: 20V, 2A
- Secondary winding 3: 20V, 2A
- Secondary winding 4: 20V, 2A
- Dimensions - 118mm x 78mm x 85mm
- Silicon-iron (STANDARD) core material
