TNC-A1256

AS-i system voltage for master, sensors, actuators, and modules

AS-Interface power supply units for power supply and unimpaired data transmission

  • High efficiency of 88 % or 90.9 %
  • Low ripple, < 50 mV or < 100 mV
  • Input and output with overvoltage protection
  • With short circuit, idle and overload protection
  • Increased operational reliability due to the bridging of voltage drops
  • Very high efficiency, hence very low heat build-up
  • LED for secondary voltage
  • Power supply units meet the requirements of VDE 0106 for AS-i networks
