TDK-Lambda Switching Power Supply, CUT35-522 3 Output 12V dc, 20.4 W, Input 265V ac to 370 V dc, 265V ac

From TDK-Lambda, the CUT35 series is a range of dual or triple output low profile switch mode power supplies (SMPS). This series simplifies system integration, requiring no minimum loading to maintain tight regulation specifications. Output one is electrically isolated from outputs two and three by using a two independent converter topology. This enables the product to be configured for dual output.

CUT35 switch mode power supplies operate from a universal 85 V ac to 265 V ac input and are available as two standard models. The CUT35-522 delivers 5.0 V ±12 V or 5.0 V and 24 V. The CUT35-5FF can provide 5.0 V ±15 V or 5.0 V and 30 V.

Packaged within the industry standard 2.0 x 4.0 in (50.8 x 101.6 mm) footprint, the converters have a low profile with a height of 27 mm.

Cooled by convection, CUT35 SMPS have an ambient temperature range of -20°C to +70°C, derating linearly to 70 per cent load from +55°C to +70°C.
