The dual-slot VME450A power supply —
filtered 28 Vdc, four output (3.3, 5, ±12 V),
550 W — is a military COTS solution that
is compliant to the vibration requirements
of MIL-STD-810F and EMI per MIL-STD-
461E. When compared to VME power
supplies using conventional technology,
the dual-slot VME450A provides users with
higher efficiency (85%), lower weight (4.4
pounds), and higher power (up to 550 W).
Built with Vicor VI Chips, it uses two
M-FIAM modules, six PRMs and six VTMs.
Aegis Power Systems, a subsidiary of the
Vicor Corporation, specializes in the
design, development, and manufacture of
rapid response custom switching power
supplies and power systems for the
defense industry.
