Line protection
To protect the mains supply line of the PS 307; 10A power supply module, you should install
a miniature circuit-breaker (for example Siemens 5SN1 series) of the following rating:
● Rated current at 230 VAC: 16 A
● Tripping characteristics (type): C.
Reaction to atypical operating conditions
Table 2-4 Reaction of the PS 307; 10A power supply module to atypical operating conditions
If ... Module reaction 24 VDC LED
.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
short-circuit at the output Output voltage 0 V; automatic voltage recovery
after short-circuit is eliminated
off
overvoltage on primary side risk of destruction -
undervoltage on primary side Automatic shut-down; automatic voltage recovery off
