Weidmuller 1469520000 PRO ECO 960W 24V 40A Switch-mode Power Supply Unit

Engineered for high-capacity DC power distribution in demanding industrial environments, the Weidmuller 1469520000 (Model: PRO ECO 960W 24V 40A) switch-mode power supply unit delivers a regulated 24 V DC output at up to 40 A. This robust DIN-rail mountable module combines a compact form factor with 93% operational efficiency, minimizing thermal load inside control cabinets and ensuring stable power delivery to PLCs, HMIs, and field actuators.

Key Features

• High Operational Efficiency: Achieves up to 93% efficiency, significantly reducing energy dissipation and cabinet heat buildup.
• Wide Input Range: Supports universal AC input from 85 to 264 V AC and DC input from 80 to 370 V DC for global compatibility.
• Tri-Color LED Diagnostics: Real-time status monitoring via Green (Uoutput > 21.6 V DC), Yellow (Ioutput > 90% rated), and Red (overload, short-circuit, or overtemperature) indicators.
• Parallel Capability: Supports direct parallel connection of up to 3 units to scale current capacity or establish redundant power architectures.
• Robust Protection Suite: Integrated varistor surge protection, short-circuit protection, overload protection, and thermal shutdown.

Industrial Applications

• Factory Automation: Centralized 24 V DC power distribution for PLC racks, I/O drops, and industrial PCs.
• Process Control Systems: Reliable power source for transmitters, solenoid valves, and safety barriers in continuous process plants.
• Machine Building: Heavy-duty power supply for packaging, material handling, and CNC machinery control panels.
• Water and Wastewater: Robust power infrastructure for outdoor telemetry and pump control stations.

Alternative Models & Compatibility

The PROeco series is designed as a highly space-efficient and cost-effective alternative to Weidmuller's premium PROmax and PROtop series. When replacing older 40 A power supplies, verify the 160 mm width footprint on the TS 35 rail, as high-power units require adequate lateral spacing for heat dissipation.

Application Pitfalls & Engineering Notes

A critical consideration for the PRO ECO 960W is its thermal derating profile. While it delivers a full 40 A at ambient temperatures up to 50 degC, the output capacity derates linearly to 24 A at 70 degC. Operating the unit near its limit in unventilated enclosures will trigger the internal thermal protection, causing output cycling.

Commissioning & Wiring Tips

Due to the high 40 A output current, ensure that output wiring is sized appropriately (minimum 10 AWG / 6 mm² copper wire recommended) to prevent significant voltage drop across the run. When configuring parallel operation for up to 3 units, use a precise digital multimeter to adjust the output voltage of each unit via the front potentiometer to within ±50 mV of each other before tying the outputs together.
