6. Description of content:    
DSLNS BS EN 61558-1: Safety of power trans formers, power supply units and similar — 
Part 1: General requirements  deals with all aspects of safety (such as electrical, thermal and 
mechanical) of:  
a) Stationary or portable, single-phase or poly phase, air-cooled (natural or forced) isolating 
and safety isolating transformers, associated or  otherwise, having a rated supply voltage not 
exceeding 1 000 V a.c. and rated frequency not exceeding 1 MHz, the rated output not 
exceeding the following values. 
Transformers incorporating electronic circuits are also covered by this standard.  This 
standard does not apply to external circuits and their components connected to terminals or 
socket-outlets of the transformer. 
DSLNS BS EN 61558-2-13: Safety of power tr ansformers, power supply units and similar 
devices Part 2-13: Particular requirements for auto-transformers for general use : This 
standards deals with all aspects of safety such  as electrical, thermal and mechanical.  This

  cooled (natural or forced), independent or associated auto-transformers, having a rated 
supply voltage not exceeding 1 000 V a.c., a ra ted frequency not exceeding 500 Hz.  This 
standard is also applicable to auto-transfo rmers having a core power up to 40 kVA, however 
such transformers are considered as special tr ansformers and are subjected to an agreement 
between the purchaser and the supplier.  Such auto-transformers have no limitation for the 
rated output. 
7. Objective and rationale, including the na ture of urgent problems where applicable:  
These standards are proposed for adoption as Saint Lucia National Standards to provide 
guidance and information to manufacturers,  importers, users, consumers and other 
interested parties, so as to ensure mini mum levels of reliability, performance and the 
protection of human health and safety.    
8. Relevant documents:
