Weidmüller PRO ECO 240W 24V 10A Switch-Mode Power Supply

Product Overview

The Weidmüller PRO ECO 240W 24V 10A (Order No. 1469490000) is a high-efficiency, slimline switch-mode power supply designed for reliable industrial automation performance. As part of the PRO ECO series, it balances high power density with essential functionality, making it an economical yet robust solution for machine construction and process industries. With a 90% efficiency rating and a compact 60mm metal housing, it is engineered to save space in the control cabinet while minimizing thermal load. Its versatile input range allows for global use, supporting both AC and DC supply voltages.

Technical Configuration

The PRO ECO 240W features a high-grade, corrosion-resistant metal housing designed for mounting on a standard TS 35 DIN rail. It provides a stable 24V DC output, adjustable via a front-facing potentiometer between 22V and 28V to compensate for voltage drops over long cable runs.

One of its standout features is the comprehensive three-color LED diagnostic system, which provides immediate visual status of the output health, load levels, and fault conditions. The unit is built for longevity, boasting a Mean Time Between Failures (MTBF) of over 2 million hours (SN 29500 standard). It also supports parallel connection of up to 5 units to increase power capacity or provide redundancy in critical systems.

Technical Specifications

Technical FAQs

Q1: What does the Yellow LED indicate?

A1: The Yellow LED is a pre-warning indicator that lights up when the output current exceeds 90% of its rated capacity (typically >9A). This allows maintenance teams to identify potential overloads before the system trips.

Q2: Can I use this power supply with a DC input?

A2: Yes, the PRO ECO 240W is a wide-range input device that can operate on 80...370 V DC, making it suitable for specialized battery systems or DC bus applications.

Q3: Is a special mounting kit required?

A3: No, the unit features an integrated snap-on foot specifically designed for standard TS 35 terminal rails.

Engineering & Installation Guide

• Thermal Management: While the unit is rated for 10A at 55 °C, note that significant derating occurs at higher temperatures. If the cabinet environment reaches 70 °C, the available current drops to 2.5A. Ensure adequate spacing (approx. 50mm vertical clearance) to allow for natural convection.

• Parallel Connection: When connecting units in parallel (max 5), ensure the output voltages are adjusted as closely as possible to the same value using the potentiometer to ensure balanced load sharing.

• Fuse Protection: For safety and protection of the supply line, a 10A Characteristic B or a 3-4A Characteristic C circuit breaker is recommended. The unit contains an internal fuse, but external backup fuses are required by most industrial standards.

• Inrush Current: Be aware of the maximum inrush current of 15A. When powering multiple units simultaneously on a single circuit, ensure the upstream breaker is sized to handle the combined peak startup current.

Engineering Advantages

The PRO ECO 240W is distinguished by its Active PFC (Power Factor Correction), which achieves a power factor of >0.94 at 230V AC, reducing reactive power costs and harmonic distortion. Its 20ms bridging time ensures that your PLC or sensitive electronics remain powered through minor mains failures or voltage dips. Furthermore, the metal housing provides superior electromagnetic compatibility (EMC) and mechanical durability compared to plastic-housed alternatives, making it ideal for the high-vibration and electrically noisy environments found in heavy manufacturing.
