Weidmuller PRO ECO 120W 24V 5A Power Supply

Weidmuller PRO ECO 120W 24V 5A switch-mode power supply, order no. 1469480000

1469480000 is the Weidmuller PRO ECO 120W 24V 5A, a compact 40 mm unit for small control panels. It supplies 120 W / 5 A at 24 V DC from a wide-range AC or DC input, in a corrosion-resistant metal case for TS 35 rail. The data sheet marks it as an article that will no longer be available in future and names PRO ECO 120W 24V 5A II as the alternative, so this page is relevant for maintenance of existing installations and for projects that must match installed units. Seven Star LLC supplies 1469480000 in Oman and the GCC as an independent supplier in Muscat.

It is the entry size of the ECO line, suited to a PLC with a few I/O modules and relay interfaces. Inrush is the highest of the three ECO sizes in the datasheet, so check the upstream breaker curve when several units start together.

Technical specifications for 1469480000

How the 1469480000 protects itself and the load

The ECO line carries overload, short-circuit and over-temperature protection, plus protection against reverse voltage fed back from the load. A front potentiometer sets the output between 22 V and 28 V. Three LEDs and a floating contact report the state: green when the output voltage is above 21.6 V, yellow when the output current is above 90 percent of rated, and red for overload, over-temperature, short circuit or output voltage below 20.4 V.

On the input side the datasheet gives 85–264 V AC (derating at for AC and 80–370 V DC (Derating @ for DC, with derating at the low end of both windows, a varistor for surge protection and an internal input fuse. Recommended external protection is a safety fuse or a circuit breaker as listed in the data sheet. Harmonic mains currents are limited according to EN 61000-3-2.

Sizing PRO ECO 120W 24V 5A against your load

Efficiency of 87 % means the supply wastes 15 W at full load, which is the heat your cabinet must remove; idle loss is 4W. The nominal current is specified at 55 °C, and the continuous rating falls at higher ambient temperature, so use the derating information in the data sheet rather than assuming full power at 70 °C. The unit bridges mains failures for the time stated in the data sheet, which keeps a PLC alive through short dips. Paralleling is allowed as stated in the table, mainly for redundancy.

Related parts and successors for 1469480000

The ECO line comes in three 24 V sizes: 1469480000 (120 W), 1469490000 (240 W) and 1469510000 (480 W). The data sheet names the II versions of each as alternatives. For higher-end requirements, Weidmuller lists the PRO MAX series, for example 1478110000, 1478130000 and 1478140000. For a compact 72 W need, 3076350000 (PRO QL) is a different design. Check dimensions before replacing one model with another, because depth and height differ between lines.

Selection checklist for 1469480000

• Confirm that your load, with start-up peaks, fits within 5 A at the cabinet temperature.
• Check the supply voltage at site against the 85–264 V AC (derating at window.
• Confirm that 40 mm of width is available (100 mm deep).
• Decide whether the successor model is acceptable for the project or if the same type is required.
• Check whether the floating alarm contact will be used.

Installation and maintenance of the PRO ECO 120W 24V 5A

Mount the unit on TS 35 rail, keeping the ventilation slots clear. Input terminals take up to 6 mm² rigid at 0.6 Nm maximum torque; output terminals take 6 mm² rigid and 2.5 mm² flexible. Check output voltage under load at commissioning and log it, then retighten the terminals after the first thermal cycles.

Typical applications in Oman and the GCC

In Oman and the GCC it is common in small packaged-equipment panels, building-services control cabinets, pump controllers and water-treatment skids where cost and rail space matter more than boost capability.
