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 VAC: 6 A
● Tripping characteristics (type): C.
Reaction to atypical operating conditions
Table 2-2 Reaction of the PS 307; 2A power supply module to atypical operating conditions
If ... ... then ... 24 VDC LED
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
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
