Power Supply KNX

 

Safe bus voltage and expanded diagnostics


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
SU/S30.640.1 Uninterruptible EIB Power Supply, 640 mA, MDRC
SU/S30.640.1 Uninterruptible EIB Power Supply, 640 mA, MDRC

SU/S30.640.1
Power supply 640 mA with integrated choke for supplying a bus line from an uninterrupted supply. Quick diagnostics via LED display for operational readiness, fault and battery level as well as a floating contact for a fault signal indication. The accumulator module or up to 2 rechargeablebatteries can be charged in normal operation by the voltage supply. The bus voltage is provided by the batteries in the event of a mains failure.
