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-75-12 for 12V PLC accessories, relays, or industrial control devices?

Yes, if the system needs constant voltage 12V DC and the total load stays within 74.4W and 6.2A. It is suited to medium-power 12V control applications rather than very low-current 12V electronics.

Is the LPS-75-12 a good fit for 12V CCTV, access control, or security hardware?

It can support 12V security and control equipment that operates from a constant voltage source and remains within 6.2A total output current. The rated output power is 74.4W.

Can this 12V power supply run embedded systems, HMIs, or small automation panels?

It can be used for 12V embedded or automation equipment where the combined draw does not exceed 74.4W. The input range of 90-264VAC also supports use across common AC supply ranges.

Is the LPS-75-12 suitable where enclosure space is limited but more 12V current is needed?

This version measures 222 x 55 x 30 mm and weighs 0.3 kg. Within that compact footprint it delivers up to 6.2A at 12V.

Can the LPS-75-12 be used in outdoor or unsealed environments?

The specs list an operating temperature range of -20°C to +70°C, but they do not list an IP rating. That means temperature capability is stated, while outdoor ingress protection is not specified in the provided data.

How does the LPS-75-12 compare with the other 12V models in the series?

In the LPS-75 series, the LPS-75-12 is the only 12V model, rated 74.4W and 6.2A. The other LPS-75 versions cover 3.3V, 5V, 15V, 24V and 48V outputs.
