Measuring peak power for rating plate

For the equipment falling under the Machinery Directive, the full load current is required to be displayed on any enclosure that receives an incoming power supply to the Machinery as defined (BS EN 60204-1 clause 16.4).


BS EN 61010-1 (safety requirements for equipment for measurement, control and laboratory use) permits either power or current to be stated.


For electronic converters (power supplies), BS EN 62477-1 is not specific about whether the information is put on a label or in the instructions or product specification documentation, but the maximum nominal rms input current is required to be stated for correct selection.


It's important you determine which standards apply to the pieces of equipment, so you can comply with the specific marking requirements of the standards (particularly for Machinery Directive where this applies).
