350 / 500W Medical Power Supplies with a 1,000W Peak Capability 

https://product.tdk.com/en/power/cus350mp www.emea.lambda.tdk.com/cus350mp 

The CUS350MP-1000 AC-DC power supplies are rated up to 350W (1,000W peak) with convection cooling for applications requiring low audible noise, or up to 500W (1,000W peak) with external airflow. The series is certified to IEC60601-1 3rd edition (medical), IEC62368-1 and IEC62477-1 (OVCⅢ) with compliance to the EN60601-1-2:2015 Edition 4 immunity requirements.   With efficiencies of up to 94%, waste heat is reduced allowing the power supply to operate reliably in a compact 88 x 183 x 44mm package size.  A 5V 0.3A standby voltage and remote on/off are fitted as standard.  The high peak power rating makes the CUS350MP-1000 suitable for use in printers and equipment utilizing DC motors.
