Hello all,
As we know, Annex L of IEC 60601-1:2005 is derived from Annex U of IEC 60950. After reading the Annex L closely, I found it is really difficult to find a triple insulated wire (TIW) to comply with 2MOPP since the test voltage of TIW for 2MOPP is too high.
For example, the max.measured voltage between HF transformer is 590 Vpeak. According to Table 6, the test voltage for 2MOPP is 4664 Vrms. So the test voltage for TIW is 9328 Vrms based on the L.3 (i.e. The test voltage is at least twice the appropriate voltage in Table 6 and Table 7).
Any thoughts?
Thanks and regards,
Roland
