مزوّد طاقة Optimus KNX بتيار 320 مللي أمبير

The 320 mA model is the compact option in the Optimus KNX power-supply range, dimensioned for smaller KNX lines — as a rule of thumb, comfortably powering line segments of up to around 32 bus devices. That makes it the natural choice for apartments, small villas, or individual sub-lines in a larger topology, where the full 640 mA capacity would go unused.

Like its bigger sibling, it generates the regulated SELV bus voltage with an integrated choke, protects against overload and short circuit, and recovers automatically after faults. If your line is planned to grow beyond ~30 devices — or you simply want headroom for future expansion — specify the Optimus 640 mA supply instead and keep the same wiring and DIN-rail footprint.

High Performance and Safety

The OPT-PS64-122 model with 640 mA output features an integrated choke circuit that directly feeds the primary KNX line, while also providing an additional auxiliary output for another line. The 320 mA OPT-PS32-111 model is ideal for compact systems. Both models include advanced protection mechanisms that automatically cut off output voltage in case of short circuit, overload, reverse polarity, voltage fluctuation, and high temperature. The system periodically checks and resumes operation once the fault is cleared.

Real-time Monitoring and Visual Feedback

The OPT-PSxx-1yy series power supplies provide real-time device status, current draw, and possible error information to the user through LED indicators on the front panel. This allows easy monitoring of system health and quick response to issues. The OPT-PS64-122 model includes a latching relay that changes contact status when the mains voltage is interrupted, enabling information transfer to BMS systems.

Easy Integration and Reliable Operation

Optimized for fast installation, reliable operation, and long service life in KNX systems, the OPT-PSxx-1yy series offers high performance in energy efficiency and system security, making it an ideal power solution for building automation projects.
