AC/DC power supply AC300

300W AC adapter

The AC/DC adapter AC300 is a new roda design based on a LLC topology for power up to 300 watt. The LLC resonant topology allows for zero voltage switching of the main switches thereby dramatically lowering switching losses. Moreover there is a synchronous rectification control on the secondary side that leads to a boosted efficiency. Efficiencies of > 98% can be achieved with LLC resonant converter. 

Besides above, the special feature of this MIL power supply is best EMC properties according to MIL-STD-461G as well as a frequency range of 50 Hz, 60 Hz and 400 Hz. The hardened and powder-coated aluminum chassis makes it dust, vibration and water resistant and meet the environmental requirements of MIL-STD-810H. Connectors on AC and DC side are freely selectable.
