Overview

LRS-75-48 is the 48V output model of this series: rated current 1.6A, rated power 76.8W, typical efficiency 91.5%.

LRS-75 series is a 75W single-output enclosed type power supply with 30mm of low profile design. Adopting the full range 85~264VAC input, the entire series provides an output voltage line of 5V, 12V, 15V, 24V, 36V and 48V. In addition to the high efficiency up to 91.5%, the design of metallic mesh case enhances the heat dissipation of LRS-75 that the whole series operates from -30℃ through 70℃ under air convection without a fan. Delivering an extremely low no load power consumption (less than 0.3W), it allows the end system to easily meet the worldwide energy requirement. LRS-75 has the complete protection functions and 5G anti-vibration capability; it is complied with the international safety regulations such as TUV BS EN/EN62368-1, BS EN/EN60335-1,BS EN/EN61558-1/-2-16, UL62368-1 and GB 4943.1. LRS-75 series serves as a high price-to-performance power supply solution for various industrial applications.

Test conditions and notes9

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 0.1uf & 47uf parallel capacitor.
3. Tolerance : includes set up tolerance, line regulation and load regulation.
4. Line regulation is measured from low line to high line at rated load.
5. Load regulation is measured from 0% to 100% rated load.
6. Length of set up time is measured at cold first start. Turning ON/OFF the power supply very quickly may lead to increase of the set up time.
7. The ambient temperature derating of 5℃/1000m is needed for operating altitude greater than 2000m(6500ft).
8. The power supply is considered a component which will be installed into a final equipment. All the EMC tests are been executed by mounting the unit on a 360mm*360mm metal plate with 1mm of thickness. 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)
9. Some model may not have the BIS logo, please contact your MEAN WELL sales for more information.

FAQ

What 48V loads are appropriate for the LRS-75-48 at 1.6A?

At 48V and 1.6A (76.8W), the LRS-75-48 suits powering single PoE injector ports, 48V control relay circuits, compact 48V DC–DC converter inputs, and low-power 48V fieldbus communication nodes. It is well-matched for systems that need a regulated 48V rail at modest current.

What operating temperature range does the LRS-75-48 support?

The LRS-75-48 operates from -30°C to +70°C and withstands 5G vibration. The -30°C rating allows cold-start in unheated industrial environments, while the +70°C upper limit accommodates warm panel enclosures.

Is the LRS-75-48 suitable for global deployment with its AC input range?

Yes. The LRS-75-48 accepts 85–264VAC, covering 100V Japanese, 120V North American, and 230V European/international mains without hardware changes. Combined with its UL62368-1, TÜV EN62368-1, GB 4943.1, BSMI, EAC, AS/NZS 62368.1 (by CB), KC and BIS approvals, it supports compliant global deployment.
