Product Overview

The SolaHD SFL24-24-100RED, an Emerson brand component, is a high-efficiency 100W switch-mode power supply designed for rigorous industrial automation environments. This unit converts universal AC input into a stabilized 24V DC output, serving as a foundational power source for Distributed Control Systems (DCS), Programmable Logic Controllers (PLCs), and field instrumentation.

Distinguished by its signature red IP20-rated enclosure, the SFL24-24-100RED is engineered for DIN-rail mounting within control panels where space optimization and thermal management are critical. It delivers high energy efficiency, typically reaching 90%, which minimizes heat dissipation and eliminates the need for forced-air cooling in most standard configurations. As an active product in the SolaHD lineup, it provides a modern, reliable solution for continuous-duty industrial applications.

Technical Characteristics and Electrical Performance

• Universal Voltage Input: Supports a wide input range from 85V AC to 264V AC (50/60Hz), making it suitable for global deployment without manual switching.

• Precision Voltage Regulation: Maintains a stable 24V DC output with a ±1% regulation tolerance, protecting sensitive electronic sensors and logic modules from voltage fluctuations.

• Integrated Safety Circuitry: Features comprehensive protection against output overvoltage, continuous short circuits, and thermal overloads to prevent hardware damage during fault conditions.

• Redundancy and Backup Ready: Fully compatible with external DC-UPS modules for applications requiring battery backup and seamless power transitions during mains failure.

• Industrial Compliance: Meets UL 508 and CE standards for safety and electromagnetic compatibility (EMC), ensuring reliable operation in electrically noisy environments.

• Efficient Installation: Designed for tool-free mounting on standard 35mm DIN rails, featuring accessible screw terminals for secure field wiring.
