The Weidmüller PROeco3 480W 24V 20A is a high-performance three-phase switched-mode power supply engineered for demanding industrial automation environments. This unit efficiently converts a three-phase AC input voltage ranging from 400V to 500V into a stable 24V DC output, providing a continuous power output of 480W and a current of 20A. Designed for integration into control cabinets, it combines reliability with a compact footprint to ensure consistent power delivery for sensitive electronic components and industrial machinery.
Advantages
This power supply unit stands out due to its high energy efficiency, which helps reduce operational costs and heat dissipation within the control cabinet. Its robust construction ensures long-term reliability even under challenging conditions, while the integrated protection features safeguard connected equipment against overvoltage, short circuits, and thermal overload. The compact design allows for space-saving installation, making it an ideal choice for modern industrial systems where panel space is at a premium.
Suitable for
- Industrial automation and control systems
- Manufacturing machinery and production lines
- Control cabinet power distribution
- Heavy-duty electrical infrastructure
This power supply is not suitable for single-phase electrical installations as it requires a three-phase AC input. It is also not intended for outdoor use unless housed in a properly rated, weather-protected enclosure.
Key specifications
- Input voltage: 400-500V AC (three-phase)
- Output voltage: 24V DC
- Output current: 20A
- Power rating: 480W
- Efficiency: High-efficiency switched-mode design
- Mounting: DIN rail mountable
To use the device, mount it securely onto a standard DIN rail within a ventilated control cabinet. Connect the three-phase AC input lines to the designated input terminals, ensuring the wiring complies with local electrical safety standards. Connect the 24V DC output terminals to your load, verifying that the total current draw does not exceed the 20A limit. Once installed, ensure all connections are tightened to the manufacturer's specified torque before applying power.
What to consider before purchase
- Verify that your facility provides a three-phase 400-500V AC power supply.
- Ensure the 480W power capacity meets the requirements of your connected devices.
- Check the available space in your control cabinet for proper heat dissipation.
- Confirm that the operating temperature range is compatible with your installation environment.
Always ensure that the power supply is installed by qualified personnel and that proper grounding is established to maintain safety and electromagnetic compatibility.
