TNC-A1258   

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 87 % or 90.9 %
■ Low residual ripple, < 50 mV or < 100 mV
■ Input and output with overvoltage protection
■ With short circuit, idle and overload protection
■ Increased operational safety due to the bridging of voltage drops
■ Very low heat buildup due to very high efficiency
■ LED for secondary voltage
■ Power supply units meet the requirements of VDE 0106 for AS-i networks
■ AS-i power supply unit TNC-1256 (8 A) with integrated data decoupling
■ Power supply for sensors, actuators and modules
■ For systems where power supply is not provided by AS-i
