3U power supply VITA 62

AC/DC

Overview
These MIL‑COTS power supplies are designed for 3U and 6U OpenVPX systems. Environmentally robust, conduction‑cooled devices that operate from nominal 28V DC or 270V DC inputs. Standard VITA 62 output voltages range from 3.3V to 12V. 3U models deliver up to 600W; 6U models deliver up to 1000W. Custom output voltages and power levels are available by request. The product family is fully tested to MIL‑STD 461G and MIL‑STD 704F. The 28V input variants additionally meet MIL‑1275E.
