Tube Filament Current Mains Transformers LL2738
LL2738 is a C-core (with small air gap) mains transformer for applications where a large number of tube filaments needs supply. Estimated power rating 160 VA which can be increased with good cooling. Magnetic stray is small if the two coils are loaded symmetrically.
Weight 2.5 kg
Copper resistance, no load output voltages and max recommended transformer current (rms) with primary connected to 230 V serial / 115V parallel
Primary res. Serial/parallel: 7.5 W / 1.9 W
Sec 15-12: 29 W / 110 V 0.1 A
All other secondaris: 0.1 W / 6.6V * 3 A
*Will drop to approx 6.3V at 3A
Please note! Output current from rectifier: 63% of above with capacitor input rectifier, 95% of above with choke input rectifier.
