Test conditions and notes6
  1. 1. All parameters NOT specially mentioned are measured at 230VAC input, rated load and 25℃ of ambient temperature.
  2. 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. 3. Tolerance : includes set up tolerance, line regulation and load regulation.
  4. 4. 33.3% Duty cycle maximum within every 30 seconds. Average output power should not exceed the rated power.
  5. 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. 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-75-24 for a 24V PLC, HMI, or automation controller?

Yes, if the equipment needs a constant 24V DC supply and the total load stays within 3.2A. This unit is rated for 76.8W, which suits many 24V control and automation devices within that range.

Is this a good fit for 24V sensors, relays, and control accessories in one enclosure?

It can be used where multiple 24V DC loads share a supply, as long as their combined draw does not exceed 3.2A or 76.8W. The wide 90-264VAC input also supports use across common AC power environments.

Can the LPS-75-24 power a compact industrial panel that needs low-profile hardware?

Yes, this model is intended for compact internal power applications with a 222.0 x 55.0 x 30.0 mm form factor and 0.3 kg weight. It provides constant 24V output up to 3.2A for panel-based equipment that fits within 76.8W.

Can I use this 24V supply in equipment that needs remote power enable control?

Yes, the LPS-75-24 includes built-in remote ON-OFF control. That can be useful in automation or embedded systems where the 24V supply needs to be switched under system control.

Is the LPS-75-24 suitable for outdoor installations?

The temperature rating is -20 degrees C to +70 degrees C, but no IP rating is provided in the listed specs. That means it is better treated as a supply for indoor or protected enclosure environments rather than direct outdoor exposure.
