Basic Information
Scope
The chapter of GB 19212.1—2008 is replaced by the following content:
This part specifies the safety requirements for switching power supply devices and transformers used in switching power supply devices. Transformers with electronic circuits are also included in this part.
Note 1: It includes electrical, temperature, and mechanical safety.
This part applies to:
a) Switching power supply devices for household and other consumer products, which are equipped with safety isolation transformers and provide AC or DC SELV, PELV, or FELV output voltages in accordance with IEC 61140 and IEC 60364-4-41, or a combination of these output voltages, except for products included in IEC 60065, IEC 61347 series, IEC 61204-7, and IEC 60950-1;
b) Switching power supply devices for household and other consumer products with a maximum output voltage not exceeding AC 1,000 V or ripple-free DC 1,414 V, except for products included in a) and products included in IEC 60065, IEC 61347 series, IEC 61204-7, and IEC 60950-1;
c) This part can be used for transformers used in switching power supply devices (see Appendix BB).
The safety requirements contained in this part apply to:
—— Separate SMPS for general use corresponding to IEC 61558-2-1;
—— Isolated SMPS for general use corresponding to IEC 61558-2-4;
—— Safety-isolated SMPS for general use corresponding to IEC 61558-2-6;
—— Self-coupled SMPS for general use corresponding to IEC 61558-2-13.
For SMPSs of other Part 2 of the IEC 61558 series for specific applications, the necessary requirements of the corresponding Part 2 apply. In addition, the requirements listed in this part also apply. If there is a conflict between the two requirements, the most stringent requirement shall prevail.
Note 2: Since the maximum rated power supply voltage of the internal transformer is 1,000 V, the maximum rated power supply voltage of the switching power supply may be lower due t
