XP Power adds compact models to MFA350 range

A XP Power product story

Edited by the Electronicstalk editorial team Feb 13, 2009

XP Power has announced additions to its MFA350 AC/DC power supply product line-up aimed at industrial applications.

The 350W compact models, which can be specified with either screw terminals or molex, are fully enclosed and offer two internally mounted fan-cooled variants.

The top-mounted fan model (-TF) measures 172.2 x 84.5 x 50.8mm (6.8 x 3.33 x 2.0in) and has a power density of up to 8W per cubic inch.

An end-mounted fan unit (-EF) is also available and measures 208.2 x 84.5 x 44.4mm (8.2 x 3.33 x 1.75in).

With the fan being internally mounted on both models, the dimensions quoted indicate the total space required, making them suitable for space-constrained applications where there is no airflow.

In addition to the fan-cooled models, the MFA350 also offers a convection-cooled U bracket and hot swappable versions.

The MFA350 delivers up to 364W from an input range of 85,264 VAC and is available in 12, 24 or 48VDC single-output versions.

A 48VDC input model, the DFA350, is also available.

An output trim function provides the ability to set the output voltage a more or less than 10 per cent of the nominal value.

The resonant topology design techniques employed in the units add to their efficiency, which is typically 86 per cent.

The MFA350 includes a 5V, 0.3A standby supply and offers a fully featured signal set including AC fail, DC OK, remote on/off, active current sharing and remote sense.

A 12V 1A fan supply is also available for the convection-cooled units.

The units will function at full power from -10C to +50C and will operate at up to +70C with derating.

The MFA350 conforms to all major international safety and EMC specifications, including Class B conducted, for which no additional external filtering components are required.
