Product Introduction
The ABB DASD103 3ASC25H283 is a high‑capacity thyristor power module designed to form an integral part of ABB’s ASTAT crane motion control system. As a “DASD” module, DASD103 handles the high‑power switching function required to drive crane motors, particularly in the hoist or trolley axes. Its 100 A rating makes it suitable for medium to heavy crane loads. Together with control logic and feedback modules, DASD103 3ASC25H283 enables coordinated, responsive motion control in demanding industrial lifting applications.
Within the ASTAT control architecture, the DASD103 module resides in the power section and interfaces with the control logic (e.g. DARA / DAPC / DAPM modules). It receives gating commands, monitors current and fault signals, and executes phase control of the AC supply to the motor. Its performance ensures smooth torque control, precise speed regulation, and safe handling of overload or regenerative events. The DASD103 3ASC25H283 module is widely adopted in crane, gantry, overhead monorail and industrial lifting systems where reliability, modularity, and serviceability are essential.
Core Advantages and Technical Highlights
High current capacity and reliability
With a 100 A rating, DASD103 3ASC25H283 supports robust crane motors and heavy loads. Its design includes thermal margins and built-in protection such as overcurrent and short‑circuit detection, ensuring dependable operation in tough environments.
Compact modular design
Despite handling high currents, DASD103 3ASC25H283 fits within the ASTAT modular chassis format. This compact layout allows easier installation, replacement, and inventory management of spare modules.
Seamless ASTAT integration
As part of ABB’s ASTAT family, DASD103 3ASC25H283 is fully compatible with ASTAT controllers, feedback modules, I/O units and diagnostic networks. This ensures synchronized performance and unified parameter setup across the system.
Efficient heat and power management
The module is engineered to minimize internal losses; at full load its power dissipation is designed to remain within manageable bounds (~30 W). This helps maintain component longevity and stable thermal behavior under load.
Diagnostics and fault handling support
DASD103 3ASC25H283 reports fault conditions such as overcurrent, thermal overload, phase failure or gating errors back to the control logic. This enables rapid fault localization and system protection before damage occurs.
Serviceability and spare‑parts continuity
Because DASD103 3ASC25H283 is a standardized ASTAT component, replacement or upgrade is straightforward. Its modular nature allows technicians to swap it quickly without disturbing adjacent modules, reducing downtime.
Typical Application Scenarios
The DASD103 3ASC25H283 module is typically used in crane and lifting motion control systems, particularly in the hoist or load axis where high current drive capability is needed. Examples include:
-
Overhead traveling cranes in steel mills, warehouses or shipyards
-
Container handling gantries or cranes in ports
-
Heavy duty monorail systems in manufacturing or assembly plants
-
Mining material handling cranes and hoists
-
Retrofit projects upgrading existing ASTAT crane control systems to newer modules
In these applications, DASD103 3ASC25H283 provides controlled drive power, smooth motion, torque limiting, and integration with safety logic in the ASTAT system architecture.
Service and Guarantee Commitment
ABB ensures that every DASD103 3ASC25H283 module undergoes factory validation, thermal cycling and functional testing before delivery. A standard warranty covers defects in material and workmanship during its service period. Maintenance support, spare modules, firmware updates and technical assistance are available worldwide through ABB’s service network. By choosing DASD103 3ASC25H283 in your ASTAT installation, you benefit from ABB’s long-term stability, spare continuity and committed lifecycle support for crane motion control systems.
