Question:
What samples to be tested in case of family step-down convertors?
Decision:
Step-down convertors, (d.c. - a.c.) (IEC 61347-2-2 / 61047) – Normally the tests are provided on all the
types of convertors with the following exceptions:
- resistance to heat, fire and tracking tests, if materials used are the same;
- heating and overload tests. It is possible to check the convertor with the maximum output if:
a) the convertors with lower wattages are identical to the maximum one (same circuit,
electronic components, lay out, external enclosure);
b) the convertors with lower wattages are provided with the same "tc" and "ta" values as the
maximum one.
