Description
Introduction
The ABB SU/S30.640.2 is an uninterruptible KNX power supply for KNX system components, designed to supply one ABB i-bus® KNX bus line with 640 mA. It includes an integrated choke and is described as short-circuit- and overload-proof, making it a dedicated system component for professional KNX line power supply planning.
For projects where bus voltage continuity is important, the SU/S30.640.2 can charge the ABB accumulator module AM/S 12.1 or up to two rechargeable batteries during normal operation. In the event of a mains failure, the bus voltage is provided using the batteries, supporting continuity for the connected KNX bus line according to the project design and official ABB documentation.

Technical Specifications
Applications
- Power supply for a single ABB i-bus® KNX bus line requiring a 640 mA uninterruptible KNX power supply.
- KNX installations where bus voltage should be supported by batteries during a mains failure, according to the selected ABB battery solution.
- System component selection for consultants, integrators, and installers preparing ABB KNX bills of quantities.
- Replacement or project matching where the old ABB Product ID GHQ6310049R0111 is referenced.
Installation Notes
- Verify that the project requires ABB SU/S30.640.2, Product ID 2CDG110275R0011, before ordering or approving the BOQ.
- Confirm that one supplied KNX line and 640 mA output are suitable for the intended ABB i-bus® KNX line design.
- Plan battery backup separately: the listed number of batteries is 0, and the product can charge AM/S 12.1 or up to two rechargeable batteries in normal operation.
- Use ABB instructions and manuals reference 9AKK107992A4835 and the official ABB product page for installation, wiring, commissioning, and safety requirements.
- Check the input requirement of 85…265 V AC, 50/60 Hz against the project electrical design before installation.
