UI39 - Low Profile Encapsulated PCB Mount Transformer - 10-30VA

A high-quality series of Low Profile safety transformers.

The Low Profile series is ideal for applications with component height restrictions such as where a close spacing between boards is needed.

Typical design is with 2x115V primary for 115V or 230V input at 50/60Hz and dual secondary with two identical output voltages.

  • Approved according EN 61558. VDE 0570
  • Vacuum cast
  • Safety class II
  • Protective system IP 00
  • Conditionally short-circuit proof (*bkf) through built-in temperature fuse,
    or not short-circuit proof (*nkf) but protected by external fuse on primary or secondary



Note: If using the conditionally short-circuit proof transformer type (*bkf) or internally connected (UI39-1./.../...) transformer type, no strip conductors may be guided between the primary connecting pins on the component insertion side, because in this area there is an unprotected live soldering terminal.
