Installation & Connection Notes
The unit is designed for installation inside a housing or control cabinet accessible only to qualified personnel. It mounts on a standard EN 60715 TH35-15/7.5 rail.
For the standard mounting position, install the unit vertically with the input and output terminals facing downward. Maintain at least 50 mm clearance above and below the power supply to support cooling.
The AC line connection uses L1, N and PE. The DC load connects to the positive and negative output terminals. Output cables must be sized for the maximum output current and protected by suitable fusing.
Application & Failure Scenarios
Where It Is Used
The 6EP1333-1LB00 is used as a 24 V DC power source in industrial control cabinets and electrical systems. Its SITOP PSU100L design is intended for basic industrial power supply requirements, providing DC power to connected control and field loads.
Why Customers Search for It
Maintenance teams may search for this unit when a 24 V DC supply is missing, unstable or unable to support connected loads, or when the power supply shows an abnormal status. Loss of control power can affect connected automation equipment and interrupt machine or process operation while the supply circuit is inspected and restored.
Operating & Diagnostic Reference
The front green LED is marked “24 V O.K.” Siemens documents that the LED lights green during normal operation when the output voltage is above 20 V ±0.5 V. The LED is off when no supply voltage is present.
The PSU100L output is designed to withstand no-load, overload and short-circuit conditions. For this 5 A model, the manual describes electronic tripping with automatic restart under short-circuit conditions. If an overload remains, the output voltage and current may be reduced and the unit may repeatedly restart.
