Not really. If the *product* is SELV, can you find any tests in 60950 that are applicable? I suspect not, unless it contains a battery of sufficient beef that a short-circuit could create a fire hazard. In that case, even though the LVD does not apply, the manufacturer should control his product liability under the GPSD by applying the standard as far as it is relevant. The same applies if there is a high voltage generated internally in a product supplied at SELV, FELV or PELV (or any other xLV that may have been invented). HOWEVER, if the product and the external power supply are marketed together, the that is a 'system' under the EMC Directive. While there is no such concept under the Low Voltage Directive, the DOC needs to apply to both parts of the 'system', so indeed it should declare conformity to EN 60950. There is also a need to put the CE mark on the product, for the EMC Directive. The comments about the GPSD are correct, but they don't actually indicate what the manufacturer needs to do physically in order to comply with all the rules. -- Regards, John Woodgate, OOO - Own Opinions Only. http://www.jmwa.demon.co.uk Interested in professional sound reinforcement and distribution?
