Hi Folks Having discussed the subject with John Woodgate before sending this message, I have now to correct his statement below that the official interpretation is that the LVD applies only to the supply side of equipment:- It does not, and it does apply to both the supply AND the output side.
This is confirmed by the Feb 2001 version (which is later than the draft that JW has of the same document) of the Commission "Guidelines on the Application of Council Directive 73/23/EEC", which can be downloaded in PDF form from the following URL: http://europa.eu.int/comm/enterprise/electr_equipment/lv/guides/index.htm See Numbered Page 3, "Which products are covered?", viz: "7. The Directive applies to all electrical equipment6 designed for use with a voltage rating of between 50 and 1000 V for alternating current and between 75 and 1500 V for direct current. Voltage ratings refer to the voltage of the electrical input or output, not to voltages which may appear inside the equipment. Following discussions with Member States the Commission has taken the position that the term "designed for use with a voltage range" shall be understood at equipment having either a rated input voltage or a rated output voltage inside this voltage range. Internally there may be higher voltages. Battery operated equipment outside the voltage rating is obviously outside the scope of the LVD. Nevertheless, the accompanying battery-charger as well as equipment with integrated power supply unit within the voltage ranges of the Directive, are in the scope of the LVD. This applies also, in the case of batteryoperated equipment with supply voltage rating under 50 V AC and 75 V DC, for their accompanying power supply unit (e.g. Notebooks). " The above guideline confirms that either the input OR the output voltage - but not the internal voltages - is the critical factor.

No. Although the wording of the LVD implies that the voltage limits apply to internally-generated voltages, there is now an official 'interpretation' that they apply only to supply voltages. -- Regards, John Woodgate, OOO - Own Opinions Only. http://www.jmwa.demon.co.uk Interested in professional sound reinforcement and distribution?
