● Competitive short delivery time.
1.Better heat dissipation achieved through vacuum encapsulation, resulting in more output power from a smaller, more compact design.
2.Vacuum encapsulation provides protection against external influences (e.g. wash operations) and mechanical stress (e.g. vibration). It also reduces the potential of noise through vibration.
3.Dimensional accuracy of each transformer guaranteed by stable and controlled manufacturing processes, allowing for automatic pick and place operations.
