Load Board designed for conduction cooled chassis
Elma Bustronic Corporation, an industry leading designer and manufacturer of high performance backplanes produces the 6U VPX Load Board in a conduction-cooled format. The board is designed per the IEEE standard 1101.2 mechanical format.
The conduction-cooled VPX load board reportedly helps confirm the chassis meets the VITA 46/48/65 power specifications for VPX and aids in locating hot spots within the enclosure. It allegedly 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.
Like the standard air-cooled version, the conduction-cooled load card has a microcontroller-based stepped load control to 100W maximum. The voltage rotary switch has settings for 3.3 V, 5 V, 12 V, +12 V Aux, – 12 V / 48 V, 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.
