Description

YB-B Series combines an IEC power-entry interface with a compact EMI line filter to simplify panel design. It’s a strong fit for equipment that needs a tidy input section with optional functional integration (depending on model configuration).

Overview Power Entry Module

  • IEC inlet format for standardized power entry
  • Integrated EMI/RFI filtering at the input boundary
  • Designed for single-phase AC lines in compact equipment

Key benefits EMI/RFI Filter

  • Helps reduce mains-borne conducted interference at the AC input
  • Supports EMC-oriented designs by lowering input noise coupling
  • Cleaner panel layout versus separate inlet + filter assembly

Typical applications

  • Portable electronic equipment and compact industrial devices
  • Communications devices and control interfaces
  • Medical and lab instruments (system-level verification required)
  • Single-phase power supply inputs and switch-mode power supplies

Selection checklist

  • Decide if you need integrated switch/fuse features (model-dependent)
  • Confirm cutout, mounting, and termination constraints
  • Review leakage/grounding strategy for your system architecture
  • Test in the final product to confirm conducted EMI margins

Note: Conducted emissions are commonly evaluated at the power terminals/lines during EMC testing; installation and grounding details matter. :contentReference[oaicite:4]{index=4}
