Elma Bustronic Corporation has announced a 3U VPX Load Board. The load board helps confirm the chassis meets the VITA 46/48 power specifications for VPX and aids in locating hot spots within the enclosure.
The load board functions to test a system’s cooling capabilities by first applying the load to the power supply for verification and creating the necessary heat to confirm chassis cooling. By locating hot spots in the chassis, a system designer can verify where to optimally redirect the airflow to prevent overheating. The 3U VPX load card features a microcontroller-based stepped load control to 100W maximum. The rotary switch selects the voltage setting while pushing the ON switch will cycle between different power levels shown on the LED display. The set load power levels are saved in EEPROM.
Other features include a power reset button (to minimum level) and a SYSRESET signal on the two test point outputs. Go-No-Go indicators are present for 3.3V, 5V, 12V, +12V_Aux, -12V_Aux and 3.3V_Aux. There is also an IEEE injector/ejector handle to provide a secure and convenient latching mechanism. Bustronic is also planning a 6U VPX Load board as well as conduction-cooled version in the coming months. The company also offers VPX backplanes, chassis, test extender boards, and SerDes test modules.
