Instrument for isolating transformer
The dry-type Isolation Transformer is widely used in circuits with AC 50Hz to 60Hz and voltage below 660V. The product's various input and output voltages, connection groups, the number and position of regulating taps (generally ± 5%), the distribution of winding capacity, the configuration of secondary single-phase windings, the use of rectifier circuits, and whether it requires a housing can be carefully designed and manufactured according to the user's requirements.
