14-12-16---VDC08A-Images-Finished-(3)VDC 50/600 Ohm Low Power Wide Band Measuring Transformers – Wide band operation models for:

  • 20Hz – 20kHz
  • 100Hz – 200kHz
  • 50kHz – 10MHz
  • 1.5 MHz to 32 MHz
  • 1 Watt Average
  • 2 Watts PEP
  • Fully encapsulated

The Minns Baluns VDC Series are designed for precision measurement purposes where 50/600 ohm transformation is required with low VSWR and high balance ratio.

All the measuring transformers are fully encapsulated within a cast aluminium case to provide a high stability product capable of withstanding the most severe environment.
