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-50-3.3 for 3.3V embedded boards, logic devices, or industrial controllers?
Yes, this is a constant voltage 3.3V supply rated for 33W and 10A. It suits 3.3V electronics and controller loads that stay within 10A total output current.
Is the LPS-50-3.3 appropriate for FPGA, MCU, or SBC power in a compact enclosure?
It can fit compact equipment because the housing is 195.0 x 55.0 x 23.0 mm and weighs 0.24 kg. The low-profile 23.0 mm design is useful where internal height is limited.
Can this model power 3.3V industrial communication or embedded I/O hardware?
It is intended for 3.3V constant voltage loads and provides up to 33W with 10A output current. That makes it suitable for 3.3V electronics in automation or embedded systems when the total load stays within those limits.
Would the LPS-50-3.3 make sense for lab or test fixtures that need regulated 3.3V DC?
It can be used for bench or fixture applications that require a fixed 3.3V output and no more than 10A. The 90-264VAC input is also useful where the AC source may vary across standard mains ranges.
Can the LPS-50-3.3 be used in hot or cold indoor equipment environments?
The specified operating temperature range is -20°C to +70°C, with output derating at higher ambient temperatures per the derating curve. The provided specs do not include an IP rating, so environmental protection beyond that temperature range is not stated.
