1 isolation transformer
1.1 to meet the "building electrical installations Part 7-710: special installations or places to get the requirements of the medical premises" GB16895.24-2005 / IEC60364-7-710: 2002 710.512.1.6 in the provisions of the medical isolation transformer should be in line with the following IEC61558-2-15 requirements.
1.2 The rated voltage Un on the secondary side of the transformer should not exceed 250 V. The medical IT system for mobile and fixed equipment should use a single-phase transformer, whose rated output capacity should not be less than 0.5 KVA but should not exceed 10 KVA.
1.3 The metal case of the medical isolation transformer needs to be coupled with local equipotential coupling terminal boards.
