1. SV/S 30.640.3.1 KNX Power Supply 640 mA: Dual Output Capability

The unit combines high power capacity with functional flexibility for complex KNX networks.

Power Capacity and Flexibility:

• Output Current: High maximum output current of 640 mA at 30 V DC on the main line.
• Dual Output: Features an additional 30 V DC output (unregulated) to supply power to a secondary line or a separate DC application.
• Decoupling: The main line has an integrated choke; the auxiliary line requires an external choke for bus operation.
• Safety: Both the main and auxiliary outputs are short-circuit and overload protected.
• Input Range: Supports a flexible wide range input from 85…265 V AC (50/60 Hz).

Monitoring and Standards:

• Status Indication: Two-color LED provides clear feedback on the bus line status.
• Standard: Generates Safety Extra-Low Voltage (SELV) for safe bus operation.
