The K-BUS KNX Power Supply, model BBPS-02/640.1, is a crucial component for KNX/EIB Home and Building Control Systems. This device is designed to produce and monitor the KNX system voltage, ensuring stable and reliable operation of connected KNX devices. It features two output connection terminals: one for KNX bus supply and signal transmission, and another for auxiliary power supply, providing a stable 30V DC voltage to terminal devices. The bus connection terminal integrates a reactor, and the auxiliary power supply terminal can also function as a bus power supply terminal with signal transmission if an external reactor is connected.

Function Description:

The KNX power supply operates as an analog-to-digital installation equipment, designed for easy installation in distribution boxes on a 35mm DIN rail, conforming to EN 60 715. Electrical connections are made via screw posts. The bus connection uses a red/black KNX connection terminal, while the auxiliary power supply connects via a yellow/white KNX connection terminal. The input end connects to a 230V AC power supply.

A key feature is the reset function, triggered by pressing the reset button for more than 0.5 seconds to reset the KNX bus voltage. A prolonged press (22 seconds, excluding button action time) initiates a power supply reset. Disconnecting the bus supply terminal from the power supply will cause other devices on the bus to return to their initial state. If the bus is disconnected for an extended period, the bus supply terminal must be removed from the power supply.

Important Safeguards and Attentions:

To ensure safe and correct operation, several precautions must be observed:

Environment: Keep the device away from strong magnetic fields, high temperatures, and wet environments. It is designed for indoor use only and should be installed in a distribution box that provides protection against electric shock.
Handling: Avoid dropping the device or subjecting it to hard impacts. Handle with care.
Cleaning: Do not use wet cloths or volatile reagents to wipe the device. Use a dry cloth and wipe with care.
Maintenance: Do not disassemble the device. The cover should never be opened. If the cover is damaged, the adapter should no longer be used.
Installation: The power supply must be installed and used according to national wiring rules.
Voltage Check: Before use, verify that the input and output voltages are correct.
Child Safety: The product is not a toy and should be kept out of reach of children.
Compatibility: This power supply is exclusively for KNX system equipment with bus line connection terminals.
Disposal: The device should not be disposed of with household waste. It must be recycled responsibly to promote sustainable reuse of material resources. Users should utilize return and collection systems or contact the retailer for environmentally safe recycling.
