Overview

NDR-75-24 is the 24V output model of this series: rated current 3.2A, rated power 76.8W, typical efficiency 88%.

NDR-75 is one economical slim 75W Din rail power supply series, adapt to be installed on TS-35/7.5 or TS-35/15 mounting rails. The body is designed 32mm 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-75 is designed with metal housing that enhances the unit's power dissipation. With working efficiency up to 89%, 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-75 a very competitive power supply solution for industrial applications.

Test conditions and notes7

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. 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.(as available on https://www.meanwell.com//Upload/PDF/EMI_statement_en.pdf )
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. Derating may be needed under low input voltage. Please check the derating curve for more details.
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).

FAQ

Can I use the NDR-75-24 for a 24V PLC cabinet power supply?

Yes, it is appropriate for 24V PLC cabinet loads that require 24VDC and remain within 3.2A and 76.8W. The DIN rail form factor and 32.0 mm slim width help when cabinet space is limited. It accepts 90-264VAC input.

Is the NDR-75-24 suitable for 24V industrial automation and control equipment?

It is a fit for 24V industrial automation and control devices when the combined load does not exceed 3.2A or 76.8W. The unit is built as a DIN rail power supply with a metal case and compact 125.2 × 102.0 × 32.0 mm dimensions. That makes it practical for organized cabinet layouts.

Can this model power 24V building management panel devices?

It can be used for 24V building management panel equipment if the total 24V demand stays within 3.2A and 76.8W. The NDR-75-24 is a DIN rail unit, which aligns with control cabinet installations. Its listed certifications are UL508, TUV BS EN/EN62368-1, and EAC TP TC 004.

How does the NDR-75-24 compare with other NDR series options?

The NDR-75-24 provides 24V at 3.2A for 76.8W. Other siblings are NDR-75-12 at 12V, 6.3A, 75.6W; NDR-75-48 at 48V, 1.6A, 76.8W; NDR-120-12 at 12V, 10A, 120W; NDR-120-24 at 24V, 5A, 120W; NDR-120-48 at 48V, 2.5A, 120W; NDR-240-24 at 24V, 10A, 240W; NDR-240-48 at 48V, 5A, 240W; NDR-480-24 at 24V, 20A, 480W; and NDR-480-48 at 48V, 10A, 480W.

Is the NDR-75-24 meant for open-area use or enclosed cabinet use?

Its DIN rail format, metal case, and slim profile point to control cabinet or enclosure use rather than exposed placement. The operating temperature range is -20°C to +70°C. This listing does not provide an external IP rating, so cabinet protection should be handled by the enclosure.
