- **Fully encapsulated low profile plastic casing in chassis mount version** 

- **2 x MOPP Medical safety according to AAMI/ANSI ES 60601-1:2005(R) and IEC/EN 60601-1 3rd edition** 

- **IT and industrial safety according to IEC/EN/UL 62368-1 and UL 508** 

- **Ready to meet ErP directive <0.3 W no load power consumption** 

- **–40°C start-up temperature** 

- **Safety class II prepared** 

- **Protection against over-temperature, overload and short circuit** 

UL 508 ES 60601-1 IEC 60601-1 UL 62368-1 IEC 62368-1 

- **3-year product warranty** 

The TMM 40C Series of fully encapsulated 40 Watt AC/DC power supply modules feature a reinforced/double I/O isolation system according to latest medical safety standards 60601-3 3rd edition for 2 x MOPP (Means Of Patient Protection). 

The high efficiency and the use of highest grade components make the units suitable for an operating temperature range of –40°C to +60°C without load derating. EMI/EMC characteristics and the safety approval package qualify these modules not only for medical devices but also for demanding applications in transportation systems and for equipment in industrial an commercial environment.
