CUS30M & CUS60M Series 

## Single Output 30 to 60W Medical & ITE Power Supplies 

www.us.tdk-lambda.com/lp/products/cus-m-series www.emea.tdk-lambda.com/cus30_60 

The CUS30M and CUS60M are  2” x 3” footprint AC/DC power supplies with outputs ranging from 5V to 48V.  They are certifi ed to IEC60601-1 3rd edition (medical), IEC60950-1 and IEC60335-1 with compliance to EN60601-1-2:2015 Edition 4 immunity requirements.  Rated at 30W and 60W, these compact products meet class B conducted and radiated EMI in either a Class I or Class II (double insulated) construction, without the need for external fi ltering.
