Description

YB-D Series is a compact single-phase EMI power line filter for control cabinets, automation systems, and AC power inputs. It helps reduce conducted emissions and improve electromagnetic compatibility for sensitive loads.

Overview Industrial AC EMI Filter

  • Designed for industrial equipment power entry and control panels
  • Supports improved immunity by lowering incoming/outgoing noise coupling
  • Broad applicability across single-phase AC devices

Noise suppression focus Conducted EMI

  • Helps suppress conducted interference at the AC input
  • Addresses both common-mode and differential-mode noise components
  • Often used to improve margin versus conducted limits in testing setups

Conducted emissions are measured at the power terminals/lines in typical compliance evaluations; filters help, but system installation is decisive. :contentReference[oaicite:7]{index=7}

Typical applications

  • Industrial automation equipment and control cabinets
  • Robotics and elevator-related systems
  • Datacom and automation subsystems
  • Power supply inputs for industrial equipment

Selection checklist

  • Match rated current range and mounting constraints
  • Choose termination style suited to cabinet wiring practices
  • Minimize loop areas and keep the filter close to the AC entry point
  • Confirm performance with final cable harness and bonding
