ABB i-bus KNX Power Supply with Two-Color LED Indicator
The ABB SV/S 30.640.3.1 is an ultra-high-capacity dedicated KNX power supply designed for ABB i-bus® smart building control systems. Engineered to generate and monitor the KNX system voltage (SELV) with exceptional stability and reliability, this power supply features MDRC (Multi-Device Remote Control) functionality and integrates a high-performance choke that effectively decouples the bus line from the power supply, eliminating signal interference and ensuring seamless, stable operation of the entire KNX system.
Featuring built-in short-circuit, overload and overvoltage protection for the 30V DC output, a two-color LED status indicator for real-time operation monitoring, and a universal wide input voltage range, this compact DIN-rail mounted power supply delivers a safe, efficient and high-performance power solution for large-scale KNX TP bus systems.
