The current relevant standard for power supplies is EN61204-3: 2000. This covers the EMC requirements for power supply units with DC output (s) of up to 200V, at power levels up to 30kW, and operating from AC or DC source voltages of up to 600V. The "EN" refers to Euro Norm or European standard. [pdf]
