Test conditions and notes7
- 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. Every output channel can provide up to the maximum current, but total load can't exceed the rated output power.
- 5. CH3(24V) peak current 20A,≦1ms, repeatable in every 100ms. CH3(24V) output must be above 16V in the period of peak current.
- 6. 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 )
- 7. 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 QP-320F for a mixed-voltage industrial control cabinet?
It can fit control systems that need multiple DC rails from one supply because this model is a quad output design with 5V, 15V, 24V, and -15V outputs. The total rated power is 316W, and the main 5V output is rated at 20A. That makes it more suitable for mixed-voltage industrial or embedded electronics than a single-output supply.
Is the QP-320F suitable for embedded test benches that need both positive and negative rails?
Yes, it is appropriate for embedded or electronics test environments that need both positive and negative DC rails, because the listed outputs include 15V and -15V along with 5V and 24V. With 316W total capacity, it is intended for systems where several regulated voltages are required from one chassis supply.
Can this power supply be used in automation equipment with a heavy 5V load?
It can suit automation or computing loads that draw heavily from 5V because the 5V output is rated at 20A. The unit is also a constant voltage design, which matches equipment that expects a fixed DC rail rather than current-regulated output.
Would the QP-320F work for industrial electronics that need wide AC input compatibility?
It is a fit for equipment that may be deployed across different AC mains regions because the input range is 90-264VAC. That makes it practical for industrial and IT hardware built for international power environments while still providing up to 316W total output.
How does the QP-320F compare with other QP series models?
Within the listed QP series, lower-power options include QP-100 variants at 100W, QP-150 variants around 146W to 152W, and QP-200 variants around 200W to 203.9W. The QP-320D and QP-320F are both 316W with 5V and 20A listed. This model stands out in the list for combining 316W with quad output capability.
Is the QP-320F appropriate for outdoor or harsh-environment use?
The stated operating temperature is -10°C to +70°C, which supports use in a broad indoor equipment temperature range. No IP rating is listed in the provided specs, so exposed outdoor or washdown suitability cannot be confirmed from this data alone.
