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
