Overview

NDR-240-24 is the 24V output model of this series: rated current 10A, rated power 240W, typical efficiency 88.5%.

NDR-240 is one economical slim 240W Din rail power supplies, adapt to be installed on TS-35/7.5 or TS-35/15 mounting rails. The body is designed 63mm in width, which allows space saving inside the cabinets. The entire series adopts the full range AC input from 90VAC to 264VAC and conforms to BS EN/EN61000-3-2, the norm the European Union regulates for harmonic current. NDR-240 is designed with metal housing that enhances the unit’s power dissipation. With working efficiency up to 90%, the entire series can operate at the ambient temperature between -20℃ and 70℃ under air convection. It is equipped with constant current mode for over-load protection, fitting various inductive or capacitive applications. The complete protection functions and relevant certificates for industrial control apparatus (UL508, TUV BS EN/EN62368-1, and etc.) make NDR-240 a very competitive power supply solution for industrial applications.

Test conditions and notes8

1. All parameters NOT specially mentioned are measured at 230VAC input, rated load and 25℃ of ambient temperature.
2. Ripple & noise are measured at 20MHz of bandwidth by using a 12" twisted pair-wire terminated with a 0.1μF & 47μF parallel capacitor.
3. Tolerance : includes set up tolerance, line regulation and load regulation.
4. Derating may be needed under low input voltage. Please check the derating curve for more details.
5. Installation clearances : 40mm on top, 20mm on the bottom, 5mm on the left and right side are recommended when loaded permanently with full power. In case the adjacent device is a heat source, 15mm clearance is recommended.
6. The power supply is considered a component which will be installed into a final equipment. The final equipment must be re-confirmed that it still meets EMC directives. For guidance on how to perform these EMC tests, please refer to “EMI testing of component power supplies.” (as available on https://www.meanwell.com//Upload/PDF/EMI_statement_en.pdf )
7. The ambient temperature derating of 3.5℃/1000m with fanless models and of 5℃/1000m with fan models for operating altitude higher than 2000m(6500ft).
8. Some model may not have the BIS logo, please contact your MEAN WELL sales for more information.

FAQ

Can I use the NDR-240-24 for a 24V PLC cabinet or machine control panel?

Yes, this unit is designed as a 24V DIN rail power supply with 240W and 10A output. That makes it suitable for PLC cabinets and machine control panels that use 24VDC and need more current capacity than smaller 120W models.

Is the NDR-240-24 a good fit for industrial automation panels with multiple 24V devices?

It is a strong fit when the panel runs on 24VDC and the combined load stays within 10A and 240W. The DIN rail form factor and 63 mm slim width support higher-capacity 24V distribution inside industrial automation cabinets.

Can this model power 24V building management and control equipment in an enclosure?

Yes, it can suit building management and control equipment that uses 24VDC, provided the load remains within the 10A, 240W output rating. The 90-264VAC input range also makes it easier to specify in control enclosures across varied AC supply conditions.

Is the NDR-240-24 intended for control cabinet use in warmer electrical rooms?

It is intended for enclosed control cabinet or electrical enclosure use, with an operating temperature range of -20°C to +70°C. The metal case and DIN rail format support industrial cabinet integration, while the specs here do not list an ingress rating for exposed environments.

How does the NDR-240-24 compare with the rest of the NDR series?

Sibling models listed are NDR-75-12 at 75.6W 12V 6.3A, NDR-75-24 at 76.8W 24V 3.2A, NDR-75-48 at 76.8W 48V 1.6A, NDR-120-12 at 120W 12V 10A, NDR-120-24 at 120W 24V 5A, NDR-120-48 at 120W 48V 2.5A, NDR-240-48 at 240W 48V 5A, NDR-480-24 at 480W 24V 20A, and NDR-480-48 at 480W 48V 10A. The NDR-240-24 is the 24V 240W option rated at 10A.
