Optimized satellite power distribution with space-rated 3U VPX card solutions.
Teledyne Micropac debuted a patent-pending, standard 3U VPX card. This card helps engineers design efficient, power-dense satellites for Low Earth Orbit (LEO) missions while meeting safety and performance requirements. The new VPX-3U-SP-PSC family of power supply cards provides up to 600W total output power in a small package the size of an index card.
Teledyne Micropac’s COTS power cards for 3U Open VPX systems support efficient development timelines. The VPX‑3U-SP-PSC accelerates design and integration times with PMBus, VITA 62, VITA 48, and VITA 78 compliance. Teledyne Micropac’s planned stocking of standard catalog items ensures shorter lead times.
The first product in the VPX-3U-SP-PSC converts 28 volts to 6 different power rails with hardware-selectable or software-commanded range of voltages. The power rails are 3.3V, 5V, and 12V (main) and 3.3V and +/- 12V (auxiliary). The PSC supports many PMBus commands. The cards will survive TID of 30KRad and are immune to SEL of 37MeV-cm2/mg. They comply with MIL-STD-704F, MIL-STD-461, and MIL-STD-1275E, and VITA 46.0, VITA 46.11, VITA 48.0, VITA 62.0, and VITA 78.0 standards.
