Test conditions and notes5
  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. 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 )
  5. 5. 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-150-3A for industrial control hardware that needs 5V, 3.3V, 12V, and -5V rails?

Yes, the QP-150-3A is a quad-output constant-voltage supply whose product name identifies 5V, 3.3V, 12V, and -5V outputs. With 146W total power and 10A on the 5V rail, it suits higher-load control and embedded systems that need several low-voltage rails from one power source.

Is the QP-150-3A appropriate for embedded computing or industrial PC assemblies with mixed DC rails?

It is well matched to mixed-rail systems because it combines 5V, 3.3V, 12V, and -5V outputs in one unit. The built-in active PFC with PF greater than 0.95 also makes it more suitable for higher-power AC-fed equipment than smaller multi-output supplies.

Would the QP-150-3A work for factory test equipment with both digital and legacy interface circuits?

Yes, this model is relevant for test and control equipment that uses 5V and 3.3V digital rails, 12V support circuits, and a -5V rail in the same chassis. Its 146W rating provides more headroom than the smaller 100W class siblings listed in the same family.

Can the QP-150-3A fit larger automation enclosures that need more output capacity than compact PT models?

Yes, it is aimed at larger multi-output loads with 146W total power and 10A on the 5V rail. Its 199.0 × 99.0 × 50.0 mm size and 0.93 kg weight reflect that higher-capacity class.

How does the QP-150-3A compare with the other listed QP siblings?

The supplied series list includes QP-100-3A, QP-100-3B, QP-100-3C, QP-100-3D, QP-100B, and QP-100C at 100W with 5V; QP-100D at 100W with -12V and 0.6A; QP-100F at 100W with -15V and 0.6A; QP-150-3B at 150.2W with 5V and 10A; QP-150-3C at 152W with 5V and 10A; QP-150-3D at 146W; QP-150B with no specs shown; QP-150C at 146W; QP-150D at 146W; QP-150F at 146W; QP-200-3A at 200W with 5V and 15A; QP-200-3B at 203.4W; QP-200-3C at 203.4W; QP-200-3D at 203.9W with 5V and 10A; QP-200-3E at 203.4W; QP-200D at 203.4W with 5V and 15A; QP-200F at 202.5W with 5V and 15A; QP-320D and QP-320F at 316W with 5V and 20A; QP-375-24B and QP-375-24C at 375W with 24V; QP-375-5A, QP-375-5B, QP-375-5D, and QP-375-5E at 375W with 5V; and QP-375-5C at 378W with 5V and 30A. The QP-150-3A itself is 146W with 5V and 10A, and its product name identifies the additional outputs as 3.3V, 12V, and -5V.

Is the QP-150-3A suitable for outdoor use or harsher temperature conditions?

The product specs give an operating temperature range of -10°C to +60°C, but they do not provide an IP rating. That means outdoor or exposed use should be evaluated carefully, with the application kept within -10°C to +60°C and ingress protection handled separately if required.
