B2B customer requirements in the medical area are being met by Conrad Business Supplies with TRACO POWER’s open-frame, switching power supply series TPP 15 and TPP 30 which offer 15W and 30W output respectively. Each series comprises eight models with input voltages ranging from 85 to 264VAC and 120 to 370VDC and output voltages ranging from 3.3 to 48VDC.

The built-in switching power supplies have reinforced insulation, are tested according to the latest medical safety standards IEC/EN/ES 60601-1, 3rd edition and meet protection classes I and II. The isolation is designed for 2xMOPP (Means of Patient Protection) requirements up to an operating altitude of 5,000m (normal height null – NHN).

Leakage current is less than 100μA, which simplifies the use for Body Floating (BF) applications. Interference resistance and noise emission of the switching power supplies comply with the latest EMC medical standard EN 60601-1-2, 4th edition.  

“Thanks to their excellent efficiency of up to 91.5%, the AC/DC switching power supplies offer a high-power density in its 1in x 2.6in format, making them suitable for medical applications where space is limited,” says Sebastian Fischer from Traco Electronic. 

Susanne Storch, Head of Product Groups Measurement, Environmental Measurement, Power Supplies at Conrad Business Supplies, adds: “B2B customers in the medical sector need a compact, high-quality switching power supply, with a temperature range of -40 to +60°C at full load and up to +85°C with 50% load reduction.” 

During the design of the switching power supply series TPP 15 and TPP 30, high-quality standards played an important role in the development. As the production of the TPP series meets these high standards, they are delivered with a five-year warranty.
