free@home Power Supply 640mA, MDRC
Description
The free@home power supply makes available the system voltage (SELV) for free@home components. The choked output voltage makes possible the energy supply and the communication of the individual free@home participants.
- Wide band of the power supply input 85 to 265 V AC 50/60 Hz
- Choked bus voltage 21 to 30 V DC
- Two-colour LED to indicate the mains voltage as well as overload and short- circuit
- Output is short-circuit-proof and overload-protected
The power supply provides the free@home bus system with the necessary system voltage.
