Extreme Engineering Solutions Inc. (X-ES) releases the XPand4201, a sub-1/2 ATR, forced air-cooled enclosure for conduction-cooled modules is designed to reduce the Size, Weight, and Power (SWaP) of deployed military systems.

 XPand4201

XPand4201 is targeted at C4ISR applications in vehicles such as UAVs, helicopters, planes, tanks and light armoured vehicles, HMMWVs, and UGVs.

A fully populated XPand4201 weighs less than 8.6kg (19 pounds) and is targeted at C4ISR applications in vehicles such as UAVs, helicopters, planes, tanks and light armoured vehicles, HMMWVs, and UGVs.

The XPand4201 conducts heat from conduction-cooled modules to heat exchangers, where the heat is dissipated to the ambient environment by forced-air cooling. Its sidewall heat exchangers are 1/2" wider than those of the XPand4200 to provide increased cooling, while a heat exchanger integrated on the top of the XPand4201 allows for significantly higher cooling capability over similar systems. Because the design supports conduction-cooled boards in an air tight enclosure, the XPand4201 provides enhanced shock and vibration protection and isolation of the boards from the outside environment.

Up to five conduction-cooled, 20.32mm (0.8inch) pitch 3U VPX payload modules and one 3U VPX power supply module can be configured into the 149.35mm (5.88inch) (W) x 152.40mm (6inch) (H) x 342.9mm (13.5inch) (D) XPand4201. The system has an optional removable memory module attachment that supports the XPort6192 Solid State Disc (SSD) Removable Storage Module, with 256GB of encrypted storage capacity. With the memory module attachment the height increases to 193.55mm (7.62inch).

The XPand4201 can be configured to meet custom I/O requirements with conduction-cooled PMC / XMC modules available from X-ES or third parties. It also supports 10Gb Ethernet, Gigabit Ethernet, graphics, RS-232/RS-422, MIL-STD-1553, ARINC 429, CANbus, CameraLink, GPIO, and digital and analogue I/O. An optional front panel USB port provides system monitoring and maintenance capabilities. There are several power supply options, supporting a MIL-STD-704 28V DC or 115V AC input, as well as internal EMI filtering and hold-up for up to 50ms.
