Technical content
The 28 V in MCC family of power systems is a new class of configurable, modular power solutions orientated to the most demandin g military applications. It incorporates active and passive filtering and congifurable outputs complying with MIL-STD-1275, MIL-STD-461, DEF-STAN 59-411 and DEF-STAN 61-5 Supplies can be specified with 1 x 400 W, 2 x 200 W, 1 x 200 W + 2 x 100 W and 4 x 100 W outputs with voltages as low as 2 VDC to as high as 48 VDC. In addition the wide trim range can provide output voltages from 500 mV to 52.8 V. The MCC is conduction cooled and relies on the use of an external heat sink. The MCC provides a low profile and rugged mechanic al construction which complies with MIL-STD-810F.
