9077 high voltage DC and DC-DC blocks

9077 high voltage DC and DC-DC blocks

The HUBER+SUHNER DC Block product line includes DC blocks (inner conductor disconnected) and DC-DC blocks (inner and outer conductor disconnected) for galvanic isolation up to 15 kV. They block high-amplitude and low frequency surge voltages e.g. occurring during regular electric railway operation along railway lines. They provide sufficient safety even in the event of the overhead high voltage lines falling to the ground.

Features

  • Galvanic isolation of the RF signal path
  • Protects from effects caused by ground potential rise
  • Provides ground potential separation
  • Protects against electrolytic corrosion caused by parasitic current
  • DC blocking configuration on inner and/or outer conductor
  • Blocking DC voltage up to 15 kV
  • Broadband operation up to 3000 MHz
  • Low intermodulation performance
  • Bulkhead mounting and grounding
  • Waterproof design
  • Maintenance free
  • Protects against electromagnetic interference caused by traction return current
