ABB i-bus® KNX power supplies provide the safe bus voltage for the connected KNX devices. Three versions for bus loads of 160, 320 and 640 mA are available, each with integrated choke and wide range mains input for worldwide usage. In addition, the 320 mA and 640 mA versions are available with expanded diagnostics for monitoring, e.g. bus voltage and current.

Main benefits

  • Less space in the distribution board required due to compact device width
  • Worldwide usage due to wide range of inputs for supply voltages from 85 to 265 V AC at 50/60 Hz
  • Premium range with expanded diagnostics for quick and efficient commissioning and monitoring

Main features

  • Bus line is decoupled from the power supply by an integrated choke
  • Voltage output is short-circuit and overload protected
  • Premium range with enhanced diagnostics provides bus state via LED display and KNX communication objects

KNX power supplies 640 mA generate and monitor the KNX system voltage (SELV). The bus line is decoupled from the power supply by an integrated choke. The voltage output is short-circuit and overload protected. The two-color LED indicates device output status. Device type SV/S 30.640.3.1 has an additional 30 V DC short-circuit and overload protected voltage output that can be used to power an additional bus line (in combination with a separate choke). With two-coloured status indicator and wide range input from 85…265 V AC, 50/60 Hz.
