Toroidal mains transformers
Advantages of the toroidal transformers over the transformer with conventional core:
-
The weight is less about 30%
-
Better efficiency
-
Lower spread magnetic space. It’s very important, it can be crucial by amplifiers, measuring instruments
-
Better cooling
Range of power: 20…3000VA. We deliver to halogen light transformer with special calculation. This makes long life time to halogen light. We deliver transformers without noise. We make these transformers with resin casting.
Remarks:
-
Sign CE, secondary voltage is 3V …. 230V.
-
We deliver the transformers with 133°C thermal fuse or thermal switch with extra price
-
We make transformers and coils according to individual request, it can be ordered with heat switch.
-
Two or more secondary coils or particular transformers we calculate an extra charge.
