What is the LVD instruction?
LVD is the low voltage directive. The name of the directive: Council Directive 73 / 23 / EEC of 19 February 1973 on the harmonization of the laws of Member States relating to electrical equipment designed for use within voltage limits.
LVD Low Voltage Directive (2014 / 35 / EU), the goal of LVD is to ensure the safety of low voltage equipment in use. The scope of application of the directive is to use electrical products with AC voltage between 50V and 1000V and DC voltage between 75V and 1500V. This directive contains all safety rules for this equipment, including protection against hazards caused by mechanical reasons. The design and structure of the equipment shall ensure that there is no danger when it is used under normal working conditions or fault conditions according to its intended purpose.
