Overview

NDR-75-48 is the 48V output model of this series: rated current 1.6A, rated power 76.8W, typical efficiency 89%.

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-75-48 for a 48V control panel or automation load?

Yes, it suits 48V control panel and automation loads that require 48VDC and stay within 1.6A and 76.8W. It is a DIN rail power supply with a slim 32.0 mm width, which helps in narrow cabinet layouts. The input range is 90-264VAC.

Is the NDR-75-48 appropriate for 48V industrial control equipment inside an enclosure?

It is appropriate for 48V industrial control equipment when the total load does not exceed 1.6A or 76.8W. The DIN rail construction and metal case support use in industrial control enclosures. Its dimensions are 125.2 × 102.0 × 32.0 mm.

Can this 48V model be used in building automation cabinets that run on 48VDC?

It can be used in building automation cabinets that need a 48VDC supply, provided the connected load stays within 1.6A and 76.8W. The NDR-75-48 is a DIN rail model, so it aligns with cabinet-based installation layouts. It carries UL508, TUV BS EN/EN62368-1, and EAC TP TC 004 approvals.

What is the difference between the NDR-75-48 and the other NDR DIN rail supplies?

The NDR-75-48 is the 48V, 1.6A, 76.8W member of this group. Other siblings are NDR-75-12 at 12V, 6.3A, 75.6W; NDR-75-24 at 24V, 3.2A, 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-75-48 suitable for cabinet environments with varying temperatures?

The specified operating temperature range is -20°C to +70°C, which supports use across a wide range of control cabinet conditions. Its metal case and DIN rail design also fit enclosed panel applications. The provided specs do not list an external IP rating, so environmental sealing comes from the enclosure rather than the power supply listing.
