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.

the output circuit is overloaded:
• I > 2.6 A (dynamic)
• 2 A < I ≤ 2.6 A (static)
Voltage dip, automatic voltage recovery
Voltage drop, reduction of service life
Flashing
short-circuit at the output Output voltage 0 V; automatic voltage recovery after short-
circuit is eliminated
