WLP75
The ABC75 Series of open frame power supplies feature a wide
universal AC input range of 85 V – 264 VAC, offering 75 W of output
power in a compact 3 x 2 x 1 inch footprint, with a variety of isolated
single output voltages.
The high efficiency and high power density of the ABC family ensures
minimal power loss in end-use equipment, thereby facilitating higher
reliability, easier thermal management and meets regulatory approvals
for environmentally-friendly end products.
ABC Series power supplies are ideal for telecom, datacom, industrial
equipment and other applications.
