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.
Most machine design engineers will survey existing component manufacturers for standard linear guide products, limiting what they can do with their designs. Using extruded aluminum profile guides can customize machine designs while shrinking the bill of materials.
Practically all electronic devices today contain metals that may
be coming from conflict-ravaged African countries. And political pressures will increasingly influence how these minerals are sourced and used in products.
