Overview

NDR-75-12 is the 12V output model of this series: rated current 6.3A, rated power 75.6W, typical efficiency 85.5%.

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-75-12 for a 12V PLC or control panel load?

Yes, this model is suited to 12V control panel and PLC-related loads that require 12VDC and stay within 6.3A and 75.6W. It is a DIN rail power supply with a slim 32.0 mm width, which helps in space-limited control cabinets. The input range is 90-264VAC.

Is the NDR-75-12 a good fit for 12V industrial automation devices inside a cabinet?

It can be used for 12V industrial automation equipment when the total DC demand does not exceed 6.3A or 75.6W. The DIN rail format, metal case, and slim size support use in compact industrial control enclosures. Its operating temperature range is -20°C to +70°C.

Can this 12V DIN rail power supply be used for building management or access control panels?

It can fit 12V building management or access control panels if the connected 12V load stays within 6.3A and 75.6W. The NDR-75-12 is built as a DIN rail power supply and measures 125.2 × 102.0 × 32.0 mm, which is useful where panel space is limited. The published certifications include UL508, TUV BS EN/EN62368-1, and EAC TP TC 004.

What is the difference between the NDR-75-12 and other NDR DIN rail models?

The NDR-75-12 is the 12V, 6.3A, 75.6W option in this group. Related models are NDR-75-24 at 24V, 3.2A, 76.8W; 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-75-12 suitable for use inside a control cabinet or enclosure?

This model is designed as a DIN rail power supply with a metal case and a slim 32.0 mm profile, so it fits well in control cabinets and enclosures. Its operating temperature range is -20°C to +70°C. The specs provided here do not list an external IP rating, so enclosure protection depends on the cabinet design rather than this product listing.
