400V single phase PCB welding synchronous transformer

Unit Price: 2.1~2.6 USD
Min. Order: 5 Piece/Pieces

Product Description

Epoxy Resin Encapsulated Single-phase Synchronous transformer DTB Series

Model: DTB3515                             Power : 3.5VA


1.DTB3515 single-phase synchronous epoxy potting Transformer has beautiful appearance


and its circuit board welding may replace similar products at home and abroad.

2.It adopts totally enclosed circuit board direct welding; the secondary output is leaded out


by weld leg; the strong electricity input and weak electricity output are separated.





  • Applied to silicon controlled power, voltage & speed governing and synchronizing signal detection
  • Sampling resistance
