A new 3U VPX Load Board 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. The 3U VPX load card features a microcontroller-based stepped load control to 100W maximum. 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 3.3, 5, and12 V +12V_Aux, -12V_Aux and 3.3V_Aux. There is also an IEEE injector/ejector handle to provide a secure and convenient latching mechanism.
