Test conditions and notes6
- 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. 33.3% Duty cycle maximum within every 30 seconds. Average output power should not exceed the rated power.
- 5. 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 )
- 6. 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 LPS-75-48 for 48V industrial or telecom equipment?
Yes, if the equipment needs a constant 48V DC supply and draws no more than 1.56A. This unit provides 75W total output, which fits 48V loads that stay within those electrical limits.
Is this 48V model suitable for embedded network or control hardware that runs on 48V?
It can be used with 48V embedded or control hardware that requires constant voltage and stays at or below 1.56A. The wide 90-264VAC input also helps when the same equipment may be deployed in different AC environments.
Can the LPS-75-48 be used in a compact industrial cabinet with limited internal space?
Yes, it is a low-profile supply with dimensions of 222.0 x 55.0 x 30.0 mm and a weight of 0.3 kg. That makes it easier to place inside compact equipment while still providing 48V at up to 75W.
Is this model a fit for systems that need remote supply control at 48V?
Yes, the built-in remote ON-OFF control can be useful where a controller needs to enable or disable the 48V rail. Electrically, the output remains constant voltage at 48V with up to 1.56A available.
Can the LPS-75-48 be used in exposed outdoor conditions?
The provided specs show an operating temperature range of -20 degrees C to +70 degrees C, but they do not list an IP rating. Because no IP rating is stated, it is better matched to indoor use or installation inside a protective enclosure.
