In addition to the following clauses, this chapter of GB/T 19212.1-2016 applies to rated values: the following clauses are added to this chapter: the rated output voltage should not exceed: for SMPS with internal separation transformers or autotransformers, it is AC 1000V or ripple free DC 1415V; For SMPS with built-in isolation transformers, it is AC 500V or ripple free DC 708V; For SMPS with built-in safety isolation transformers, it is AC 50V or ripple free DC 120V. For independent SMPS with built-in separate transformers or autotransformers, the rated output voltage should exceed AC 50V or ripple free DC 120V, but not exceed AC 1000V or ripple free DC 1415V. The rated output of SMPS should not exceed 1 kVA or 1 kW. Note: For transformers installed in SMPS, please refer to Appendix BB. The rated power frequency should not exceed 500 Hz. The rated internal operating frequency should not exceed 100MHz. The rated power supply voltage should not exceed 1100 V AC. Verify compliance with 6.101~6 by checking the markings 105.
