Elma Bustronic Corp.'s 6U VPX Load Board in a conduction-cooled
format is designed per the IEEE standard 1101.2 mechanical
conduction-cooled VPX load board helps confirm the chassis meets the VITA
46/48/65 power specifications for VPX and aids in locating hot spots within the
enclosure. It helps test a system's cooling
capabilities by applying the load to the power supply for verification and
creating the necessary heat to confirm chassis cooling. The board features external voltage monitoring, load
stepping, and GO-NO-GO indicator LEDs.
The conduction-cooled load card
has a microcontroller-based stepped load control to 100W maximum. The
voltage rotary switch has settings for 3.3, 5, 12V, +12V_Aux, - 12 /
48V, and Sys Reset. The set load power levels are saved in EEPROM. Bustronic
also offers VPX load boards in a 3U form factor and 6U air cooled formats.
One of the biggest walls in embedded software development is the integration of low-level drivers with higher-level middleware and application code, but silicon vendors are stepping up to bring it down.
