 Introduction |
The new KCH-903 series is the new improved version of 4U chassis designed for industrial applications. This rugged, all-steel chassis meets the EIA RS-310C 19" rackmount standard. The KCH-903 series allows installation of multiple PC systems in a single chassis that includes not only a serial 14-slots passive backplane but also a more efficient switching power supply in a single fan-cooled chassis. The KCH-903 series will withstand shock, vibration, dust, and a wide range of operating temperatures in harsh industrial environments. The chassis is positively pressurized by one filtered push-pull cooling fans to exclude dust and dirt. A lockable door protects drives and switched from tampering and foreign particles.
