11U Rugged Enclosure

Highly ruggedized system enclosure, constructed of solid seam-welded alumninum with a 6U 19-slot floating card cage.

Form Factor: 11U
Part Number: OSS-ENCL-11U-1866

Product Features

  • Ruggedized enclosure supports 3U, 6U, CPCI, and VME backplanes
  • EMI-shielded chassis made of solid seam- welded aluminum
  • Convection cooled with six- fan, high CFM cooling system
  • Floating card cage that sits within the enclosure and is surrounded by four banks of looped cable isolators.
  • Dampening clips in the card cage guides provide additional insulation to ensure reliability and performance under the harshest conditions.

Specifications

Chassis

Card Cage

The 19-slots wide card cage includes shock isolation coils and supports a 6U backplane with 160mm front section and 80mm rear section for rear transition modules.

Cooling

Each system uses 6 AC axial fans for cooling the chassis.

Front Panel Display

Six LEDs on the front of the chassis indicate Sysmon Good, Temperature Status, Power System Status, “System Up” indication, Minor Fault, Major Fault.

System Monitor

Control and Monitoring Features
  • Monitors temperature sensors 1-8
  • Monitors fan tachometers 1-8
  • Monitors voltages +12V, +5V, +3.3V, -12V, +5V (additional voltages up to 8)
  • Monitors up to 8 GP inputs (may be used for DC power signals, etc.)
  • Controls up to 8 GP outputs (may be used for LEDs, etc.)
Network Configuration
  • Stored in nonvolatile memory and retained without power
Power Consumption
  • 237mA at 5V = 1.2 watts     
  • <-- the board runs on 5V only
  • Can be quickly and easily changed
  • Dip switch settings allow network configuration to restore to default settings
Mechanical
  • 4 inches L (9cm) x 3 inches W (7.6cm)
  • 0.76 inches (1.9cm) stack height with passive heat sink
Temperature/Humidity
  • Operating Temperature — 40° to 85° C (32° to 185° F)
  • Storage Temperature — -40° to 85° C (-40° to 185° F)
  • Humidity — 5% to 90% non-condensing

Power Supply

The system is powered by 3 individual AC/DC power supplies.   +5VDC, +3.3VDC, +12VDC, -12VDC, and +5VDC (AUX).  The +5VDC (AUX) is present whenever AC power is present and is used for powering the System Monitor Board.

AC Power

AC power is supplied via AC Receptacle at the rear of the chassis and is wired using Teflon insulated cable to the AC Circuit breaker, at the front of the chassis.  From the AC breaker, the AC power is routed to the power supplies and AC fans.  The AC breaker is the main power switch to the system. A circuit breaker cover plate is provided on the chassis.
