Enertex® KNX Dual PowerSupply 1280

2-in-1 KNX power supply, 1280 mA + 320 mA, din rail (6 SU)

The power supply KNX DUAL PowerSupply 1280 (6 SU) offers three voltage outputs: KNX output with 1280 mA, KNX output with 320 mA and a unchoked 30 V output with 320 mA. Further Features: Display, diagnostic functions and time switches.

• 2-in-1 KNX power supply for supplying two KNX lines
• Main line with integrated KNX choke for 1280 mA output current
• Secondary line with integrated KNX choke for 320 mA output current
• Additional third unchoked 30 V auxiliary voltage output for 320 mA output current with 100% overload capability
• Separate short-circuit and overcurrent limitation for each output
• No influence by short-circuit of one output to the others
• High efficiency of over 90% at nominal load (efficiency before the choke)
• Measurement of voltages, currents, power, telegram bus load, bus voltage failures and internal device temperature on KNX bus via group objects
• Integrated bus coupling unit with (optional) KNX Data Secure communication
• OLED display for clear indication of all important measurement and device data
• Display of current values including time and date
• 16 extensive time switches with 4 switching times and 4 group addresses each, including extensive logic functions, holiday calendar and astro function
• Integrated KNX clock, buffered against power failure (power reserve approx. 36 hours)
• Separate remote reset function (triggering bus resets via a group address) for both KNX lines
• Bus telegram on exceeding or falling below parameterized limit values
