External a.c.. d.c. and a.c.. a.c. power supplies. Determination of no-load power and average efficiency of active modes Ingestion-build-47553 including in vitro medical devices1 Scope This European Standard specifies methods of measurement of electrical power consumption, and the reporting of results, for external power supplies. This standard is applicable to external power supplies with a rated input voltage within the range 100 V a. c. to 250 V a. c. having a single output with a rated output power not exceeding 250 W and a rated output voltage not exceeding 230 V a. c. or 325 V d. c. The output voltage may be either at
