Dear Koh,
The IEC 335-1 is the Standard of Household and Similiar
Appliances, General Requirements. The IEC 742 pertains to Isolating
transformers and Safety isolating transformers requirements. Both of these
standards have equivalent EN standards which are EN 60335-1, and
EN 60335:95. The standard noted below EN 60335-2-207 I as of now cannot find
any reference too. The IEC and EN standard on 335 are still valid for the
European market, so my question is what market are you selling into?
Mark

Dear EMC-PSTC,
My company is currently designing a speaker system meant for ITE (that
is PC) connection.
The speaker requires external supply which the hardware team is looking
into using a AC/AC adaptor instead of AC/DC adaptor.
This AC/AC adaptor which steps down the 230Vac or 110Vac to the required
low voltage for the speaker supply.
A supplier of such AC/AC adaptor has said that their product complies to
EN60335-1 standards.
As I'm not familar with this standard, and need advice on the following
doubts.
1) Is this EN60335-1 equivalent to IEC 742 ?
2) Heard from a colleague (from his source) that EN 60335-2-207 should
be the standard ?
3) Was browing through the LVD Harmonised standard and unable to find
this 60335-2-207. Could someone advice what is this standard ?
4) Is this supplier statement of the AC/AC adaptor conforms to EN60335-1
sufficient? Or should this AC/AC adaptor meant for household &
electrical appliance required to fulfil EN60335-2-207 standard ?
5) Does EN60335-1 applicable to AC-AC adapter only ?
6) Are this standards (EN60335-1 and EN60335-2-207) still valid? Or it
has been obsolete/replaced?
7) Could this AC/AC adapter that complied with EN60335-1 be bundled with
ITE product meant for Home or Office use?
Looking forward to you advice.
Thanks in advance.
Regards
Koh
