DC-DC CUSTOM POWER SUPPLY UNITS

VISIONPOWER's DC-DC Custom PSUs are used in a variety of applications including Avionics, Military, Telecoms, Datacomms and Industrial applications.

Avionic and Military project applications range from military aircraft (including NH 90, TIGER, Tornado), commercial aircraft (Airbus A320, A330, A340 and Boeing 737NG), to ground mobile equipment, including armoured vehicles (including the Warrior Fighting Vehicle) and other sub-marine applications.

Telecoms and Datacoms project applications range from Short Haul Optics, Terminal Equipment, Amplifiers, Transponders with transmission speeds up to 40Gbit/s, to Advanced Telecoms Computing Architecture (ATCA).

Product Range

VISIONPOWER can offer both modular and fully custom (discrete) design solutions. VISIONPOWER's DC-DC PSUs cover a wide range of styles and features. The examples below feature a small selection of VISIONPOWER's DC-DC solutions:
