Industrial Applications

Process Automation Systems: Powers distributed control systems (DCS), programmable logic controllers (PLCs), and field instrumentation in chemical plants, refineries, and pharmaceutical facilities where uninterrupted operation is critical.

Manufacturing Automation: Supplies reliable power to robotic cells, CNC machinery, conveyor systems, and assembly line controllers in automotive, electronics, and consumer goods production environments.

Infrastructure & Utilities: Supports SCADA systems, remote terminal units (RTUs), and telemetry equipment in water treatment plants, power substations, and pipeline monitoring installations.

Building Management Systems: Energizes HVAC controllers, access control panels, fire alarm systems, and energy management platforms in commercial and industrial facilities.

Transportation Systems: Powers signaling equipment, traffic management controllers, and railway automation systems requiring fail-safe power delivery.

Design & Performance Features

Industrial-Grade Construction: The 26kg weight reflects heavy-duty components including oversized transformers, high-capacity filtering capacitors, and reinforced heat sinks designed for continuous 24/7 operation in temperatures ranging from -25°C to +70°C.

Voltage Regulation: Advanced feedback circuits maintain tight output voltage tolerance (typically ±1%) despite input fluctuations and load variations, protecting sensitive electronic equipment from damage.

Overload Protection: Integrated current limiting and thermal shutdown mechanisms prevent catastrophic failures during fault conditions, automatically recovering when normal conditions resume.

EMC Compliance: Shielded design and filtering components minimize electromagnetic interference (EMI) emissions while providing immunity to industrial electrical noise from motors, drives, and switching equipment.

Installation & Integration

The DSSA 165 mounts securely on standard 35mm DIN rails commonly found in industrial control cabinets and electrical enclosures. Terminal blocks accept a wide range of wire gauges for flexible field wiring. The unit's modular design allows parallel operation for redundancy or increased capacity in critical applications.

Maintenance Considerations: Field-replaceable components and accessible terminal connections simplify preventive maintenance and reduce mean time to repair (MTTR). LED status indicators provide at-a-glance operational feedback for troubleshooting.

Quality & Availability

Manufactured at ABB's Swedish production facilities under ISO 9001 quality management systems, each DSSA 165 undergoes rigorous factory testing including burn-in cycles, voltage regulation verification, and safety ground continuity checks. The unit ships from multiple global distribution centers including Sweden, United States, and Singapore for rapid delivery.
