Description
Efficient power delivery in decentralized industrial automation systems is critical, and the Weidmuller 1469510000 switch-mode power supply unit is engineered to meet this demand. Operating within the PRO eco series, this robust power supply delivers a regulated 24 V DC output with up to 20 A of continuous current, translating to a nominal output power of 480 W. It features a wide-range AC input (85 to 264 V AC) and DC input (80 to 370 V DC) capability, making it highly adaptable to varying global grid conditions.
The compact, corrosion-resistant metal housing is optimized for space-constrained control cabinets, mounting directly onto standard TS 35 DIN rails. With an energy efficiency rating of 91%, the unit minimizes thermal dissipation, allowing reliable operation in ambient temperatures ranging from -25 degC to 70 degC. Integrated safety features include short-circuit protection, overload protection, over-temperature protection, and reverse voltage protection, ensuring maximum uptime for connected PLC, DCS, and I/O systems.
Features
- High-efficiency power conversion reaching up to 91% to reduce heat generation inside enclosures.
- Wide input voltage range supporting both AC (85 to 264 V AC) and DC (80 to 370 V DC) operation.
- Adjustable output voltage from 22 to 28 V DC via a front-facing potentiometer for precise voltage drop compensation.
- Three-stage LED diagnostic indicator for real-time visual status monitoring of output voltage and load conditions.
- Support for parallel connection of up to three units to increase total output capacity or establish redundancy.
- Robust screw connection system ensuring secure, vibration-resistant wiring.

Installation Guidelines
-
Mounting: Snap securely onto a standard TS 35 DIN rail. Ensure the unit is mounted vertically to facilitate natural convection cooling.
-
Clearance: Maintain a minimum clearance of 50 mm above and below the unit, and 10 mm on the sides when operating under full load conditions.
-
Wiring: Use appropriately rated copper conductors. Ensure all screw terminals are torqued to the manufacturer's specified limits to prevent contact resistance.
-
Grounding: Connect the protective earth (PE) terminal to the local system ground busbar prior to energizing the input power.
