Line protection
The mains supplies of the PS 307;10 A 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: 10 A
● Tripping characteristics (type): C.

.output circuit is overloaded:
• I > 13 A (dynamic)
• 10 A < I ≤ 13 A (static)
Voltage dip, automatic voltage recovery
Voltage drop (reduction of service life) flashes
