John, Yes, The AC device falls into the scope of the LVD including the EMCD. This must be tested at system level due to the leakage currents and the like. It appears in this case the batteries require charging via the AC device, this is a component of the system and must be tested accordingly.
-----Original Message----- From: [email protected] [mailto:[email protected]] Sent: Thursday, January 13, 2000 9:44 AM To: [email protected] Subject: LVD voltage range. Hello all, Does a hand-held field device that operates mainly on 12Vdc from a group of batteries and alternatively uses an AC/DC adapter need to be assessed for safety according to the LVD? I read somewhere that for LVD the DC voltage should be between 75 and 1500V. Does this mean that such a device does not need to be evaluated for safety at all ? A client is awaiting a response from me in a couple of hours so I would appreciate any views on this matter. Thanks for your usual co-operation.
