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.

FEATURES

Medical and ITE approvals

Compact size 2” x4” x1.18”
