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.
Producing high-quality end-production metal parts with additive manufacturing for applications like aerospace and medical requires very tightly controlled processes and materials. New standards and guidelines for machines and processes, materials, and printed parts are underway from bodies such as ASTM International.
Engineers at the University of San Diego’s Jacobs School of Engineering have designed biobatteries on commercial tattoo paper, with an anode and cathode screen-printed on and modified to harvest energy from lactate in a person’s sweat.
