🔧 Main Functions
- Conversion of AC mains voltage into 24 V DC.
- Power supply for industrial electronic devices.
- Power supply for SMA monitoring and communication systems.
- Direct installation inside electrical panels using DIN rail.
- Visual indication of output voltage through the DC OK LED.
🔌 Purpose and Operation
The device receives the input mains voltage and converts it through a switching stage into a stabilized 24 V DC voltage, with up to 2.5 A available.
The 24 V DC output can be used to power electronic control, communication and monitoring equipment. The front DC OK LED indicates the presence of the correct output voltage; Phoenix Contact specifies that the LED illuminates when the output voltage exceeds approximately 21.5 V.
🧩 Compatibility
The product is marketed by SMA as CLCON-PWRSUPPLY and is intended for powering equipment such as:
- SMA Data Manager
- SMA Cluster Controller
- SMA Inverter Manager
-
SMA COM Gateway
SMA documentation identifies Phoenix Contact model 2868651 as a 24 V DC / 2.5 A DIN rail power supply.
⚠️ Typical Faults and Symptoms
In case of malfunction, the following may occur:
- absence of 24 V DC output voltage;
-
DC OK LED off;
- connected SMA device not powered;
- equipment restarts or shuts down;
- insufficient output voltage;
- activation of the internal protection in case of overload or abnormal conditions.
A power supply fault should not be confused with a failure of the connected SMA device: the input, output and load must be checked separately.
🔍 Diagnosis
Diagnosis may include:
- checking the AC mains input voltage;
- checking the DC OK LED;
- measuring the output voltage;
- checking for possible overload on the 24 V circuit;
- checking terminals and connections;
- checking operation with a compatible load.
🛠️ Common Services in Case of Failure
- Power supply testing.
- AC input measurement.
- DC output measurement.
- Load testing.
- Terminal inspection.
- Overload diagnosis.
- Power supply replacement in case of failure.
