85441

What type of power supply is this?

This is a DIN-rail mounted single-phase industrial power supply designed to convert a wide AC or DC input into a stable 24 V DC output for panel-based automation and control applications.

What input voltage range does it accept?

It accepts a wide input range of 85 to 265 V AC at 50 to 60 Hz, or 90 to 250 V DC. This flexibility makes it suitable for use across many industrial power systems.

What output does it provide?

The unit provides a nominal 24 V DC output at 10 A. The output voltage is adjustable from 24 to 28 V DC, which can be useful where a small voltage increase is needed to compensate for cable losses or application requirements.

Is the output voltage adjustable?

Yes. The output can be adjusted between 24 and 28 V DC using the onboard potentiometer. Factory setting is typically around 24.1 V DC.

How much current can it deliver?

At 24 V DC, it delivers 10 A continuously up to +60°C, and up to 12 A at temperatures up to +45°C. At 28 V DC, the available continuous current is lower, with up to 8.5 A at +60°C and up to 10.2 A at +45°C.

Does it offer extra power for start-up loads?

Yes. It includes a Power Boost function that can provide 150% of nominal output power for at least 4 seconds. It also offers a short Hyper Boost capability of up to 450% of nominal current for at least 20 ms at 60°C, which helps with demanding inrush conditions.

Can it be mounted on a DIN rail?

Yes. It is designed for TH35 DIN-rail mounting in accordance with EN 60715. For proper convection cooling, it should be mounted with the rail in a horizontal orientation.

What are the dimensions and weight?

The housing measures 123 mm high, 65 mm wide and 138 mm deep, with a weight of approximately 0.85 kg. This compact format helps when panel space is limited.

Is this unit suitable for panel and cabinet installation?

Yes. It is intended for installation inside a control cabinet or enclosure, where natural convection can be maintained around the device.

What is the operating temperature range?

The operating temperature range is -40°C to +60°C. Derating begins from +45°C. Storage temperature range is -40°C to +80°C according to the product datasheet, with some operating instruction versions listing storage up to +85°C.

What protection features are included?

The power supply includes output overload protection and short-circuit protection. It also has temperature-related protective behaviour to help prevent damage if ventilation is restricted or load conditions become excessive.

Does it have an alarm indication?

Yes. It features a bi-colour LED for output status indication and a potential-free alarm contact. When output voltage is OK, the contact is closed and the LED shows green; in alarm condition, the contact opens and the LED shows red.

Can multiple units be connected together?

Yes. Up to 5 units can be connected in parallel, provided their open-circuit voltages are set equally and the secondary cabling is matched. Up to 2 units can be connected in series while maintaining SELV output limits.

How efficient is the unit?

Efficiency is up to 94.3% at 230 V AC and approximately 92.8% at 110 V AC. High efficiency can help reduce heat build-up inside the panel.

What ingress protection rating does the housing have?

The housing is rated IP20. This means it is intended for use inside an enclosure rather than in exposed environments.

What connection type does it use?

The unit uses spring clamp terminals for input, output and alarm connections. This allows secure wiring for typical industrial cabinet installations.

Is this model suitable for applications requiring stable 24 V DC power?

Yes. 85441 is intended for applications that need a regulated 24 V DC supply, such as PLC systems, I/O modules, sensors, relays and other industrial control equipment within a cabinet environment.

Does it support both AC and DC input operation?

Yes. In addition to standard AC input operation, the unit can also be operated from a DC input source within the specified range, which adds flexibility in certain system designs.
