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-150-3B for industrial electronics that need 5V, 3.3V, 12V, and -12V rails?

Yes, the QP-150-3B is a quad-output constant-voltage model whose product name identifies 5V, 3.3V, 12V, and -12V outputs. With 150.2W total power and 10A on the 5V rail, it is suited to higher-demand control, computing, and interface systems using those four rails.

Is the QP-150-3B a good fit for automation or control assemblies that mix digital logic and bipolar support circuits?

It can be a strong fit when the system uses 5V and 3.3V logic rails together with 12V and -12V support rails. The built-in active PFC and PF greater than 0.95 also align with larger AC-powered industrial equipment.

Would the QP-150-3B work for test racks or embedded platforms that need more capacity than a compact multi-output supply?

Yes, this model is in a larger power class at 150.2W, with 10A available on the 5V rail. Its 199.0 × 99.0 × 50.0 mm dimensions and 0.93 kg weight reflect that higher-capacity format.

Can the QP-150-3B support legacy or mixed-interface equipment that specifically needs a -12V rail instead of -5V?

Yes, that is one of the main distinctions of this version. Its product name identifies the output set as 5V, 3.3V, 12V, and -12V, which makes it relevant where a -12V rail is required in the overall system design.

What are the differences between the QP-150-3B and the other listed QP family models?

The QP-150-3B is a 150.2W quad-output model with 5V, 3.3V, 12V, and -12V rails. Other models in the QP-150 series vary by output configuration and power rating; for example, the QP-150-3A has a -5V rail instead of -12V, while the QP-150-3C features 15V and -15V rails. Specific current ratings and total wattage differ across the series, so verify the datasheet for the exact model required.

Is the QP-150-3B rated for outdoor environments or only temperature-controlled locations?

The supplied specs state an operating temperature range of -10°C to +60°C, but they do not list an IP rating. For environment suitability, keep the installation within -10°C to +60°C and account separately for any required protection against exposure.
