Cosel has launched the HFA3500TF, a low-profile three-phase, three-wire 3,500W AC/DC enclosed power supply design optimized for industrial equipment such as semiconductor manufacturing, laser processing machines and robotics.
Addressing worldwide applications and 3-phase Delta or 3-phase Star networks, the supply input voltage ranges from 180 to 528VAC. Using the latest ‘energy optimized’, digitally controlled switching topology and wide band gap (WBG) semiconductors, the supply offers an efficiency figure up to 94 per cent at 400VAC input and 65VDC output.
The supply is available in two output voltages, 48 and 65VDC, adjustable in the range +15 to -50 per cent using the trim function. The compact, low- profile design comes in at 41mm high with cover and features two variable speed cooling fans. For higher power applications the supply can be connected in parallel up to ten units, delivering up to 31.5kW.
The low-profile design fits into the vertical space of a 1U rack unit, advantageous in applications where space is a premium, facilitating easier integration into compact machines, saving floor or rack space in industrial environments.
