DA, DACB, DANF – Matching transformers


Designed and tested according

DA:
IEC/EN61558-2-4/EN60076-11

DACB:
EN 60076-1

DANF:
IEC/EN61558-2-4/EN60076-11
EN 55011

Typical applications

DA u. DACB:
Matching transformer for machine and plant components

DANF:
Matching transformer for machine and plant components which do not comply with the EMC directives. This faciliates compulsory marking and easy system integration.

Technical notes

DA advantages:

  • flexible voltage adjustment by primary tapping
  • static shield winding between primary and secondary winding
