1 Scope

GB 19212.1-2008 this chapter is replaced by the following. GB This section 19212 specifies the shaver transformers, power supply units built shaver transformers and shaver supply unit Safety requirements. With electronic circuits shaver transformers are also included in this section. Note 1. Safety requirements including electrical, temperature, mechanical and chemical. Unless otherwise specified, the following "transformer" includes shaver transformers, power transformers built shaver and shaver supply unit Means. This section applies in a vertical, single-phase air-cooled (self-cooled or air-cooled), with independent or supporting the use of dry-type transformers. Windings can be Encapsulated or non-encapsulated type. This section applies to the internal operating frequency not exceeding 500Hz transformers and power supply (linear). This section also applies to the internal operating frequency exceeding 500Hz power and should be used in conjunction with GB 19212.17. When the two standards When a conflict, give priority to the most stringent standards. Rated supply voltage not exceeding AC 250V, rated supply frequency not exceeding 500Hz. 20VA rated output of not less than and not more than 50VA. Load output voltage does not exceed AC 275V, and the rated output voltage does not exceed AC 250V. This section does not apply to scheduled to be connected to the input and output terminals or output receptacle transformer circuit and external components. When installation procedures or between the bathroom and electrical specification requirements for the installation site similar circuit is double or reinforced insulation, you can use this It comprises a portion of a transformer. Note 2. This section includes a transformer can be fitted in or surface mounted on the lighting and mirrors, or mount containing one or more of its output socket He inside the machine. Note 3. The following should be noted. --- Transformer predetermined use on a vehicle, ship or aircraft, additional requirements may be necessary (according to other applicable standards, national regulations, etc.); --- Avoid the housing and the housing components such as protective measures by the outside influence of mold, insects, termites, solar radiation, and icing should also be considered; --- Transformer transport, storage and different conditions of work should also be considered; --- Intended to be used for special circumstances transformers can be used in line with national standards and other applicable rules of the additional requirements. Note 4. With the future development of transformer technology, may need to increase the upper limit frequency, but before then, you can use this section as a guide.
