30-48 WATT MEDICAL & ITE SWITCHING POWER SUPPLIES
TMC40 SERIES
DESCRIPTION
The TMC40 series of compact, open PCB constructed, AC-DC
switching power supplies are capable of delivering 30-48
watts of continuous output power at convection cooling. They
operate at 90-264 VAC input voltage without the need of
voltage selection, and are suited for medical, information
technology and industrial applications. Approval to both
EN60601-1 and EN60950-1 safety standards improves
design-in time and reduces end equipment compliance costs.
