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-10-3.3 for 3.3V embedded controllers or logic boards?

Yes, this model is built for constant 3.3V DC output and can support embedded logic boards, controllers, and similar electronics that require 3.3V. Its output is rated at 8.25W and 2.5A, so the connected load needs to stay within those limits.

Is the PM-10-3.3 suitable for industrial 3.3V communication or interface electronics?

It can be used for low-power industrial communication or interface electronics that run on 3.3V DC. The unit supplies up to 2.5A at 3.3V with a wide 85-264VAC input range, which suits internally powered equipment using standard AC input.

Can this power supply run a 3.3V microprocessor or embedded I/O module?

It is appropriate for 3.3V microprocessor and embedded I/O applications when the total demand stays at or below 8.25W and 2.5A. Because it is a constant-voltage design, it is intended for electronics that specifically require a regulated 3.3V supply.

Is the PM-10-3.3 intended for outdoor use?

The operating temperature range is -20C to +70C, with output derating at higher ambient temperatures per the derating curve, and the specs do not list an IP rating. That usually makes it a better choice for indoor equipment, control cabinets, or other protected enclosures rather than exposed outdoor locations.
