40 WATT MEDICAL POWER SUPPLIES
DESCRIPTION
The PM40AL series of compact, open PCB constructed, AC-DC
switching power supplies are capable of delivering 40 watts of
continuous output power. They operate at 85 to 264 VAC
input voltage without the need of voltage selection. They are
ideally suited for use in medical equipment, safety systems and
monitoring equipment, not for patient contact.
