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 0.1uf & 47uf 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. The final equipment must be re-confirmed that it still meets EMC directives.
  5. 5. Touch current was measured from primary input to DC output.
  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 PM-15-3.3 for 3.3V embedded electronics or controller boards?

Yes, it is a constant-voltage 3.3V supply with up to 3.5A output current. It is suited to embedded or control electronics that require a regulated 3.3V rail and stay within 11.55W total output.

Is the PM-15-3.3 appropriate for low-voltage logic loads in industrial equipment?

It can be a match for 3.3V logic-level loads used inside industrial or automation assemblies. The available capacity is 3.5A at 3.3V, with 11.55W maximum output power.

Can this model support a 3.3V communication or processing module in an embedded system?

It is designed for constant 3.3V output, so it can support embedded processing or communication hardware that is specified for 3.3V DC input. Load sizing still needs to remain within 3.5A and 11.55W.

Is the PM-15-3.3 suitable for outdoor or harsh exposed locations?

The operating temperature range is -20°C to +70°C, which covers a broad temperature window. However, no IP rating is listed, so the specs do not identify this unit as protected for outdoor exposure, dust ingress, or water ingress.
