TNC-A1256

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

AS-interface power supply units for system supply and unimpaired data transmission

■ High efficiency of 88 % 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 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 (2.8 A) with integrated data decoupling

■ Power supply for sensors, actuators and modules

■ For systems where power supply is not provided by AS-i
