35W triple output power supply simplifies system integration

March 21, 2017 // By Graham Prophet
TDK’s 35W rated CUT35 power supplies require no minimum loading to maintain tight regulation specifications. Output 1 is electrically isolated from outputs 2 and 3 through the use of a two-independent-converter topology, enabling the product to also be configured for dual output.

Target applications include process control, broadcast, test & measurement, and industrial equipment. The CUT35 operates from a universal 85 to 265 Vac input and is available as two standard models. The CUT35-522 delivers 5V and ±12V or 5V and 24V, and the CUT35-5FF can provide 5V and ±15V or 5V and 30V. Packaged in the industry standard 2 x 4 in. (50.8 x 101.6mm) footprint, the converters have a 27mm height.


The convection cooled CUT35 has an ambient temperature range of -20 to +70°C, derating linearly to 70% load from +55 to +70°C. Typical efficiencies are between 81 and 82%. Over voltage and over current protection is provided as standard and the units are covered by a three-year warranty. The series carries certification to UL/CSA/IEC/EN 60950-1 and carries the CE mark for the Low Voltage and RoHS2 Directives. All models comply with EN 55011/55022-B conducted and radiated emissions and the EN 61000-4-2 immunity standards.
