## 1500W Medical and Industrial Power Supplies 

https://product.tdk.com/en/power/cus-m www.emea.lambda.tdk.com/cus1500m 

The CUS1500M are 1500W rated AC-DC power supplies with output voltages from 12V to 48V.  They are certified to IEC60601-1 3rd edition (medical) and IEC62368-1 with compliance to the EN60601-1-2:2015 Edition 4 immunity requirements.  The series is also certified to EN62477-1 (OVC III).  These 7-year warranty[(1)] products feature low acoustic noise (<45dBA) and meet both class B radiated and conduction EMI standards. Features include an isolated 5V 1A standby voltage, remote on/off and an output-low/fan-fail isolated signal.  Up to five units can be connected in parallel for additional power.
