Overview

NDR-240-48 is the 48V output model of this series: rated current 5A, rated power 240W, typical efficiency 90%.

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-240-48 for a 48V industrial control panel?

Yes, this model provides 48VDC output at up to 5A with a total power rating of 240W. Its DIN rail construction and 63 mm slim profile make it suitable for industrial control panels built around 48VDC power distribution.

Is the NDR-240-48 suitable for 48V automation systems inside a control cabinet?

It is suitable when the automation system requires 48VDC and the total demand stays within 240W and 5A. The 63 × 125.2 × 113.5 mm enclosure is sized for DIN rail mounting in cabinet-based automation layouts.

Can this power supply be used for 48V building automation or monitoring equipment?

Yes, it can support building automation or monitoring equipment that operates on 48VDC and fits inside the 5A output limit. The 90-264VAC input range is also useful when specifying one DIN rail supply across different facility power conditions.

Should the NDR-240-48 be used in a protected enclosure?

This unit is best suited to protected control cabinets and electrical enclosures rather than exposed locations. The specified operating temperature range is -20°C to +70°C, and the listed metal case supports industrial cabinet use, but no ingress rating is shown here.

What are the differences between the NDR-240-48 and the other NDR DIN rail models?

The NDR-240 series includes the NDR-240-24 (240W 24V 10A) and the NDR-240-48 (240W 48V 5A). Other NDR series models like the NDR-75 and NDR-120 have lower power ratings, while the NDR-480 series offers higher power at 480W.
