Shield Enclosure

  • EMI-Shield-Enclosure-Tent
  • EMI-Shield-Enclosure-Tent-Test-1
  • EMI-Shield-Enclosure-Tent-Test-2

Overview

  • Shielded enclosure (EMC Tent) of various sizes can be easily used when it is difficult to install a shielded room due to space and cost problem.
  • Box type shielded enclosure is recommended for small device test, and room type shielded enclosure is recommended when operation in large equipment or shield space is required.
  • Easy to move / install / disassemble due to the prefabricated structure, and excellent shielding effectiveness by made of conductive fiber material and double door structure.

Features

  • Same performance as shielded room for less cost
  • Excellent shielding performance
  • Easy to move, install and disassemble with prefabricated structure
  • So called, EMC Tent

  • Installation Features
Inner installation

Inner enclosure can be easily installed inside the outer enclosure using one-touch method

Support

By providing a support at the bottom between the inner and outer enclosure, even if the test equipment is placed inside the inner enclosure, it does not allow the shield rate drop by electric short.

Power passage

Insulation sheet is inserted into the power path between inside and outside to prevent short.
