Product features
Supplying power at the system level rather than for individual devices
The design of DSSA165 48990001-LY Power Supply Unit is intended to power the entire control system, rather than a single module. This makes it more suitable for industrial control cabinets with multiple loads operating in parallel in terms of output capacity, stability, and protection strategies.
High current output, reducing power supply dispersion, and deployment
The 24 V DC, 25 A output capability allows multiple control units, I/O racks, and field interfaces to share the same power supply, reducing the number of power modules and, from the system structure perspective, lowering the number of failure points.
Industrial continuous operation-oriented design
DSSA165 48990001-LY Power Supply Unit is not a short-cycle or intermittent operation device. Instead, it is designed for 7×24-hour continuous operation scenarios and is suitable for systems such as process control and critical production lines that do not allow frequent shutdowns.
Wide input voltage adaptability
Supports multiple AC input voltage standards, enabling stable operation in different countries and on-site power grids, reducing the complexity of adaptation during the project design phase.
Native compatibility of the control system
DSSA165 48990001-LY Power Supply Unit is compatible with systems such as ABB Advant Master in terms of electrical interfaces, installation method,s and operational characteristics, avoiding potential compatibility or long-term stability issues that may arise when using a universal power supply.
The maintenance cycle is predictable.
It supports the official preventive maintenance plan, enabling the aging of the power supply, component replacement, and maintenance cycle to be planned. This helps factories carry out planned maintenance and reduces the risk of sudden downtime.
The structure is stable and suitable for heavy industrial environments
DSSA165 Power Supply Unit weight and structural design emphasize mechanical strength and heat dissipation capacity, making it suitable for installation in industrial control cabinets with high temperatures, high vibrations, or complex electromagnetic environments.
Common application scenarios
Power supply for industrial control cabinetProvide a stable 24 V DC power supply for PLC, controller, I/O modules, and communication units.
DCS/PLC system
Used in process control systems to ensure the long-term continuous and stable operation of the control system.
ABB Advant Master system
As the native matching power module, it supplies power to the core control unit of the system.
Automated production line
Supports the power supply for critical control equipment, reducing the impact of power fluctuations on the production process.
System maintenance and upgrade
For the replacement or maintenance of the power supply in the existing ABB control system, the system structure remains unchanged.
