This is an overview of the Phaseo range of ASI ABL power supplies. These power supplies deliver the required 30 VDC to the AS-Interface bus. The outgoing terminal block allows the network cable to be connected separately to the AS-Interface modules and to the AS-Interface master. They have input and output LEDs for fast and continuous diagnostics.
These are single-phase, electronic, switch mode power supplies that provide the necessary quality of the output current to conform to the EN 50295 standard.
There are 3 types in this range of power supplies:
The Basic power supplies are:
-
ASI ABL B3002: Outputs 30 VDC 2.4 A, 72 W
-
ASI ABL B3004: Outputs 30 VDC 4.8 A, 144 W
ASI ABL B2002 and the Basic schematic:
These power supplies add diagnosis and management of earth faults. In the event that an earth fault is detected, the Phaseo power supply stops communication over the AS-Interface cables and puts the system in the configured fallback mode. It can only be restarted after acknowledgement of the detected fault. Two Inputs/Outputs allow communication with a processing unit. These modules also have an earth fault diagnostic LED.
The Detection power supplies are:
-
ASI ABL D3002: Outputs 30 VDC 2.4 A, 72 W
-
ASI ABL D3004: Outputs 30 VDC 4.8 A, 144 W
ASI ABL D3004 and the earth fault schematic:
The ASI ABL M3024 provides 2 totally independent power supplies:
-
30 VDC 2.4 A, 72 W supply for the AS-Interface bus
-
24 VDC 3 A, 72 W supply that can power control equipment
