Line protection
The mains supply of the PS 305 power supply module (2 A) should be protected with a
miniature circuit-breaker (for example Siemens 5SN1 series) of the following rating:
● Rated current at 110 VDC: 10 A
● Tripping characteristics (type): C.
Reaction to atypical operating conditions
Table 2-1 Reaction of the PS 305;(2 A) power supply module to atypical operating conditions
If ... ... then ... 24 VDC LED
... the output circuit is overloaded:
• I > 3.9 A (dynamic)
• 3 A < I ≤ 3.9 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
