Purchase now: Wago 750-613 System Power Supply
Purchase now: Atlantech Drives provides you the Wago 750-613, a critical infrastructure component for large I/O nodes: the **System Power Supply Module**. In the Wago 750 system, the Fieldbus Coupler supplies the internal 5V data bus power. However, standard couplers can only supply around 1000 mA to 1700 mA. If you have a node with 40+ complex modules (like Ethernet cards, safety modules, or analog cards), you will exceed this limit. The 750-613 is inserted into the assembly to **inject new power** into the internal data bus, allowing you to add more modules.
Technical Specifications and Functionality
The 750-613 takes an external **24 V DC** input and converts it into the **5 V DC System Voltage** required by the I/O electronics. It provides up to **2000 mA (2 A)** of additional current to the internal bus. Simultaneously, it refreshes the **24 V DC Power Jumper Contacts** (Field Power) to supply the sensors and actuators downstream. It essentially «resets» the power budget of the node without interrupting the data communication.

Expert Installation Advice: Where to place it?
Don’t guess; calculate. Expert Tip: Use the free **Wago Smart Designer** or refer to the «Current Consumption» datasheet of every module. Sum up the 5V current draw of your modules. The moment the total exceeds the coupler’s supply (e.g., > 1.7A), you MUST insert a 750-613 at that position. If you don’t, the modules at the end of the rack will fail to initialize or behave erratically (blinking LEDs) due to voltage sag on the backplane.
Frequently Asked Questions (FAQs)
Q: Does it create a new «Node»?
A: No. The 750-613 is transparent to the data. All modules after it are still part of the same Fieldbus Coupler station. It only refreshes the power.
Q: Is this the same as 750-602?
A: No! The 750-602 only refreshes the *Field Power* (24V Jumpers) but passes the *System Power* (5V) through. The 750-613 refreshes BOTH.
