SAFT112POW Industrial Power Supply Unit

Description

SAFT112POW

The SAFT112POW is a high-reliability industrial power supply unit engineered specifically for ABB’s Symphony Plus and AC 800M control systems, providing regulated DC power to critical control components. As a foundational element in control system infrastructure, this power supply converts incoming AC mains power into stable DC output required by I/O modules, processors, and communication devices.

SAFT112POW

Its design focuses on delivering consistent performance across varying input conditions and load demands, making it ideal for mission-critical applications in power generation, oil and gas, and pharmaceutical industries. What distinguishes the SAFT112POW is its combination of robust protection features and compact design, offering system integrators a space-efficient power solution that enhances overall system reliability through stable power delivery.

Main features and advantages:

A key strength of the SAFT112POW is its advanced power regulation technology, which maintains precise output voltage (24V DC ±0.5V) even during input voltage fluctuations between 85V and 264V AC. This ensures connected control components receive consistent power regardless of mains voltage variations common in industrial environments. The unit incorporates comprehensive protection mechanisms including overload protection, short-circuit protection, overvoltage protection, and thermal shutdown, preventing damage to both the power supply and connected equipment during fault conditions. Hardware-wise, the SAFT112POW features a rugged metal housing with efficient heat dissipation, enabling reliable operation in temperatures ranging from -25°C to 70°C. Its modular design supports easy installation in standard control cabinets, while status indicator LEDs provide instant visual feedback on operational status and fault conditions.

Application areas:

In industrial control environments, from power generation facilities to chemical processing plants, a stable and uninterrupted power supply forms the foundation of reliable automation operations. Control systems, I/O modules, and communication devices depend on consistent power to maintain process integrity, safety functions, and data continuity. Fluctuating power or unexpected outages can lead to process disruptions, equipment damage, or even safety incidents in critical applications. This is where the SAFT112POW excels, serving as a dedicated power supply unit designed to deliver clean, regulated power to ABB’s control system components in demanding industrial settings. Used in industrial automation applications ranging from distributed control systems (DCS) to safety instrumented systems, the SAFT112POW addresses key challenges such as voltage stability, surge protection, and seamless integration with ABB’s automation platforms.

Installation and maintenance:

Before installing the SAFT112POW, ensure the mounting location provides adequate ventilation and is free from direct exposure to moisture, corrosive gases, or excessive vibration. Verify that the input power circuit includes appropriate overcurrent protection sized to the unit’s specifications (maximum 10A for 230V AC input). The DIN rail should be securely fastened to prevent movement that could strain electrical connections. Maintain a minimum clearance of 50 mm above and below the unit to facilitate proper heat dissipation, especially when multiple power supplies are installed in close proximity. Ensure proper grounding of both the input power and the unit’s protective earth terminal to minimize electrical noise and meet safety standards.

For optimal maintenance of the SAFT112POW, implement a monthly inspection schedule to check status indicators and verify stable output voltage using a calibrated multimeter. Perform quarterly visual inspections to check for loose connections, signs of overheating (discoloration, unusual odors), or dust accumulation on heat sinks. Clean ventilation areas semi-annually using compressed air to maintain thermal performance. Monitor load levels regularly to ensure they remain below the unit’s rated capacity (12A), as continuous operation at maximum load can reduce service life. During scheduled maintenance, verify that all protection features are functioning correctly by performing controlled overload and short-circuit tests according to ABB’s recommended procedures.
