(1) Build characteristics according to standards IEC 950, IEC 1131-2, guaranteeing user safety on the 24V output, in terms of insulation between primary and secondary, maximum overvoltages on the output wires, and ground circuit protection.
(2) Possibility of connecting 2 power supply outputs of the same type in parallel, in order to provide an output current greater than the maximum permitted with a single supply.
(3) For 2 modules supplying a total current of 100%, each module provides 50% of the total current. This improves the product service life.
(4) Connection of 2 power supply outputs of the same type in parallel, in order to provide an output current less than the maximum permitted with a single supply, but ensuring continuity of the output voltage even if one of the two modules becomes faulty.
