Product Overview

The Emerson 1X01047H01L1 is a high-density power conversion module engineered specifically for the Ovation™ Distributed Control System (DCS). This industrial-grade power supply serves as a foundational component for control cabinet infrastructure, transforming raw AC utility power into the highly regulated 24V DC required by sensitive I/O modules, controllers, and field transmitters.

Engineered for the rigorous uptime requirements of the power generation and water treatment industries, the 1X01047H01L1 ensures system stability by providing a clean, low-noise DC bus. Its design emphasizes energy efficiency and thermal management, allowing it to maintain peak performance within the dense, high-temperature environments of integrated control cabinets.

Key Technical Characteristics and Performance

The 1X01047H01L1 is defined by its superior regulation capabilities and robust protection circuitry.

• High-Efficiency Conversion: Achieves over 92% efficiency at 230V AC, minimizing heat dissipation and extending the operational lifespan of the module and surrounding electronics.

• Stable DC Output: Delivers a consistent 24V DC with stringent line regulation (±0.5%) and load regulation (±1.0%), ensuring that voltage drops do not occur during high-demand process cycles.

• Clean Power Delivery: Features specialized filtering that keeps ripple and noise below 100 mVpp, protecting sensitive digital electronics from electromagnetic interference.

• Dynamic Load Support: Provides a continuous 10A output with a peak capacity of 12A to accommodate the high inrush currents often associated with starting field actuators or inductive loads.

• Fault Ride-Through Capability: Maintains output stability for over 20ms during brief AC power interruptions, allowing the DCS to bridge minor grid fluctuations without triggering a system reset.

• Inrush Current Limitation: Active circuitry limits initial surge current to under 25A, preventing the nuisance tripping of upstream circuit breakers during system startup.
