Technical data

Power supply

"ASi power supply":

Special power supplies with integrated data decoupling unit for use in ASi-3 only networks. Suitable for all Bihl+Wiedemann ASi-3 gateways and safety monitors.

"30 V power supply":

Inexpensive standard power supplies, suitable as an alternative for use with ASi gateways and safety monitors with integrated data decoupling unit (version "1 power supply, 1 gateway for 2 ASi networks, inexpensive power supplies") and with all 24 Volt ASi gateways.


30 V power supply, optimized for ASi-5/ASi-3:

Inexpensive standard power supplies, optimized for use with ASi-5/ASi-3 gateways and safety monitors with integrated data decoupling unit (version "1 power supply , 1 gateway for 2 ASi networks, inexpensive power supplies") and with all 24 Volt ASi-5/ASi-3 gateways. In order to avoid interferences in ASi-5 communication, Bihl+Wiedemann recommends the use of power supplies optimized for ASi-5/ASi-3.


30 V power supply, optimized for ASi-5/ASi-3, NEC class 2 :

The 30 V/3 A power supply is UL certified, has power limitation <100 W and is designed for use in NEC class 2 networks. It is suitable for applications with 1 power supply per ASi network. In the case of power intensive applications, Bihl+Wiedemann recommends the use of a 30 V power supply without 100 W power limitation in combination with a power limitation module (BWU4189) for each ASi network.The power supply is optimized for use with ASi-5/ASi-3 gateways and safety monitors with integrated decoupling coils (version "1 power supplies, 1 gateway for 2 ASi networks, inexpensive power supplies") and with all 24 V ASi-5/ASi-3 gateways. In order to avoid interferences in ASi-5 communication, Bihl+Wiedemann recommends the use of power supplies optimized for ASi-5/ASi-3.


"ASi power supply decoupling unit":

Supply of 2 ASi networks out of 1 power supply. Applicable with double masters without integrated data decoupling.


"Power decoupling unit":

Take up to 1,2 A out of ASi. In combination with an ASi Repeater: decouples 1,2 A from ASi Segment B and supplies Segment A with 1,2 A.

ASi power supply
Input voltage 90 ... 265 VAC, wide range supply
Output current 4 A
Data decoupling coils

Integrated in the power supply:

Data decoupling is performed in the special ASi power supply with integrated data decoupling unit. ASi gateways and safety monitors missing their own, integrated data decoupling unit require a special ASi power supply for each ASi network.

Integrated in the gateway:

Bihl+Wiedemann ASi gateways and safety monitors with integrated data decoupling unit (version "integrated decoupling, ASi current measurement in the gateway") can be operated with an inexpensive 30 V standard power supply.
