XP Power continues to increase the flexibility of its range of AC/DC power supplies with the launch of the MFA350. Believed to be the world's smallest 350 W power supply, the base platform achieves 11.2 Watts per cubic inch power density. The product is designed specifically for telecom and datacom applications, such as storage area networks, data networking and post-production broadcast equipment. Its design facilitates a multitude of packaging and power options, including a hot-swap version. The base product delivers 364 W across the entire input range of 90-264 VAC from an 81mm x 173mm x 38mm (3.2" x 6.8" x 1.5") U-bracket package. It is available in 12, 24 and 48 VDC output versions. The MFA350 includes a 12V, 1A fan supply and a 5V, 0.3A standby supply and, despite its small size, offers a fully-featured signal set including AC fail, DC OK, remote on/off, active current sharing, and remote sense.

The unit will function at full power from -10 degrees C to +50 degrees C, and will operate at up to +70 degrees C with derating. The MFA350 is 89% efficient, so only 13CFM airflow is needed for full output power. This has been achieved by the optimisation of proven technology, which includes the use of silicon carbide (SiC) diodes to increase efficiency, lower noise and reduce component count.

High efficiency and ease of thermal management make the power supply ideal for telecommunications equipment, where high power density and compact redundant power systems are a pre-requisite of space-constrained applications. Hot-swap models have oring FET outputs, front access IEC inlets and extraction handles. The MFA350 family is designed with a 1U x 2U profile, allowing vertical or horizontal orientation in standard telecom chassis. A DC input version will also be available.
The units conform to all major international safety and EMC specifications.
