Line protection
The mains supply of the PS 307; 2A power supply module should be protected with a
miniature circuit-breaker (for example Siemens 5SN1 series) of the following rating:
● Rated current at 230 V AC: 3 A
● Tripping characteristics (type): C.
Reaction to atypical operating conditions

If ...
the output circuit is overloaded:
•
I > 2.6 A (dynamic)
2 A < I ≤ 2.6 A (static)
•
short-circuit at the output
