ITR900-0116 | Interra KNX Power Supply 160 mA: Micro-Sized Bus Voltage Generator
Like its larger counterparts, the power supply includes an integrated choke to ensure the bus line is properly decoupled, facilitating clean and stable data communication. It features global compatibility with a wide-range mains input (85…265 V AC, 50/60 Hz). System safety is guaranteed as the voltage output is protected against short-circuits and overloads, with a two-color LED (Green/Red) for clear status indication.
The ITR900-0116 is a cost-effective and essential component for adding power to the smallest KNX bus segments where space is limited.
