NIMpact 300W

NIMpact crates are low cost crates that meet EUR4100 and CE specifications. They are outfitted with a 300W power supply with overload and over temperature protection. 5U NIMpact crates are without fan tray.


  • Fully wired 12 slot crate, 5U
  • Stabilized steel card guide structure
  • Simplified control panel with On/Off switch and status LED
  • Bin equipped with long-life NIM connectors, all lines wired according to CERN or CE specifications
  • Integrated linear regulated 300W power supply
  • AC input 230V/50 Hz or 110V/60Hz
  • Dimensions: 19″ (483mm) x 5U (222.3mm) x 518mm [whd], weight: ca. 26Kg
  • CE Conformity

Technical Information

NIMpact NIM Bin 5U

Non-ventilated 518mm deep 5U NIM bin with 12 slot. Aluminum construction with stabilized steel card guide structure. Power supply is fixed mounted rear side.
The power-bus-system is equipped with 12 high-quality long-life NIM connectors on a power backplane.

Connector pins made of massive brass, gold plated.
Simplified ½ slot wide control panel with on/off switch and status LED.

Current maximum ratings:
