The ABC275 Series of ultra low profile open frame power supplies
feature a wide universal AC input range of 80
–
264 VAC, offering
output power 275 W with 13 CFM forced air cooling, or up to 160 W
with convection cooling. The power supplies are available in 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.
These power supplies are ideal for broad range of telecom, datacom,
industrial equipment and other applications.
