Test conditions and notes7
  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. The over temperature protection (OTP) is the built-in function of the control IC (U1). The activating level described above is based on the specification provided by the IC manufacturer.
  6. 6. Touch current was measured from primary input to DC output.
  7. 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 NFM-10-5 for a 5V single-board computer or embedded controller?

It is designed for constant 5V output and can supply up to 2A with a 10W rating. That suits many compact embedded controllers, microprocessor boards, or digital logic assemblies that run on 5V. The connected load needs to stay within both the 2A and 10W limits.

Is the NFM-10-5 a good choice for 5V industrial USB-style electronics or interface boards?

It can fit 5V interface electronics if the total demand does not exceed 2A. In industrial or automation equipment, that makes it more appropriate for lower-power communication boards, converters, or logic hardware than for larger 5V loads. The wide 85-264VAC input supports common global AC input ranges.

Can this model power 5V sensors, relays, and logic in a small control panel?

It can support mixed 5V control electronics where the combined load remains within 10W and 2A. That is useful for compact assemblies with a modest 5V demand rather than systems with heavy actuator loads. Its small 65.0 x 45.0 x 22.0 mm size also helps in space-limited panels.

Is the NFM-10-5 suitable for indoor and outdoor environments?

The specified operating range is -20C to +70C, so the temperature tolerance is broad for protected equipment use. No IP rating is listed in the provided specs, so the product data does not confirm sealing against dust or water. Based on that, it should be treated as suitable for protected environments unless a separate rating is provided.

How does the NFM-10-5 compare with other 5V NFM power supplies?

The listed 5V siblings are NFM-05-5 at 5W and 1A, NFM-10-5 at 10W and 2A, NFM-15-5 at 15W and 3A, and NFM-20-5 at 22W and 4.4A. The NFM-10-5 is the mid-range option between the 5W entry model and the higher-current 15W and 20W versions. If your 5V load needs more than 2A, a larger sibling would be required.
