Figure 1 Block diagram 3U All voltage ZVS converters are isolated (1500V isolation voltage) and fed via a common Filter Network from the same 28V main supply (19V – 35V, shortly 36V). 3V3aux is not independent but protected by a resettable fuse (PTC). All individual output voltages (6x) are sensed by window comparators for over- and under voltages which are monitored from a central control logic device (CPLD). Any failure on the output voltages are signaled on the front panel by corresponding FAIL LEDs and lead to a switch off of all voltages (by default). If all internals are normal the...

Figure 2 Front panel functional elements of the VPX3C Power Supply 1.1.3 Control Logic: Depending on the main bus signals also the green RUN LED goes on and the power supply tries to start working. According to VITA 62 and VITA 46 the logic run line condition is – when “#” is nomenclature for the negative logic main bus signals, logic negation is signaled by the “¬” sign, and a positive logic transition by “↑”: RUN = ( ¬ #ENABLE AND #INHIBIT AND #FAIL AND ¬INTERNAL_FAIL ) “REFRESHED AFTER FAIL WHEN” ↑ ( ¬ #SYSRESET) This means that if the global inhibit is not set (= released to H), whether...

1.1.6 Switch-On Behavior All voltage outputs are switched on exponentially with relatively slow rise times of 30-80 ms and do settle smooth to the final voltage without any overshoot or glitch. Figure 3 Startup Delay and Exponential Rise (orange) of VS1 = 12V Output Voltage The power supply has to be switched on by a source of a minimum ramp up speed of the 28V source voltage of > 50 V/s or a maximum ramp up time < ~500 ms. If the ramp up time is longer than half a second the control logic may stall during switch on.

VPX Power 3U / 6U All voltage converters are isolated (1500V isolation voltage) and fed from the same 24V main supply (18V – 36V) protected by two (DCin1, DCin2”) 40A fuses. The “Power LED” is controlled by the “Power Good Signal” of the 12V converter. The output voltages (+12V, +5V, 3,3V) are sensed for over- and under voltages which are monitored from the control logic in every converter. Any failure on the output voltages are signalled on the front panel by corresponding FAIL LED (OFF). In according to Vita62, the “FAIL-Signal” is connected to the “FAIL Pin” (B2) at the P1 connector.
