An end mounted fan unit (-EF) is also available and measures 208.2 x 84.5 x 44.4 mm (8.2 x 3.33 x 1.75 inches). With the fan being internally mounted on both models, the dimensions quoted indicate the total space required making them ideal 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 364 W from an input range of 85 – 264 VAC and is available in 12, 24 or 48 VDC single output versions. A 48 VDC input model, DFA350, is also available. An output trim function provides the ability to set the output voltage +/- 10% of the nominal value. The resonant topology design techniques employed in the units contribute to them being highly efficient; typically 86%.
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 -10 degrees C to +50 degrees C, and will operate at up to +70 degrees C 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.
The MFA350 family is available from Farnell or direct from XP Power.
