DG Series Single-Phase Dry-Type Control Isolation Transformer uses high-B cold-rolled silicon steel sheets combined with a vacuum impregnation process, along with a low magnetic flux and low current density design, resulting in features such as lower noise, lower temperature rise, and stronger overload capacity. It is widely used in electromechanical equipment, step-up/step-down power supplies, test system power supplies, lighting, UPS bypass, zero-ground voltage elimination, and high-purity sine wave power supply voltage for imported equipment with demanding requirements. The various input/output voltages, connection groups, allocation of tapping winding capacities, and whether a cabinet is included can all be carefully designed and manufactured according to user requirements.
