Product Details

• Part Number 1 DSSR122
• Part Number 2 48990001-NK

Product Description

For Master system applications, ABB DSSR122 provides the function of a Rack Power Supply.

For replacement planning, power-supply modules form the electrical foundation of an automation system by delivering conditioned operating power to the equipment assigned to their supply circuit. The product should be matched to the documented control-system position.

For system maintenance, this product is associated with the Master family and the PLC modules category. Configuration and compatibility should be confirmed for the exact system in which it will be used. The product remains part of the broader control and signal-handling arrangement.

In the signal path, this approach helps preserve the intended system function while keeping selection aligned with the documented ratings, capacity, and compatibility requirements. Installation should follow the control node's approved hardware records.
