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-05-5 for a 5V microcontroller or embedded system?

This unit outputs 5V constant voltage at up to 1A, with 5W total power. That makes it a fit for low-power 5V embedded systems, controller boards, and logic hardware that stay within those limits.

Is the NFM-05-5 suitable for a small USB-class 5V electronics load?

It is suitable for 5V electronics when the load does not exceed 1A or 5W. The fixed 5V constant-voltage output is appropriate for devices designed for a regulated 5V supply rail.

Would this 5V model work for compact industrial interface electronics?

Yes, for compact 5V interface, indicator, or communication electronics that fit within the 1A output limit. The 58.0 x 45.0 x 19.1 mm dimensions also make it practical where internal mounting space is tight.

Can the NFM-05-5 be used in equipment shipped to regions with different AC mains?

The input is rated at 85-264VAC, which covers a broad AC input range. That is useful for 5V equipment intended for deployment across sites with different mains voltages.

What are the main differences between the NFM-05-5 and other NFM models?

At the lower end of the range, the series includes NFM-05-3.3 at 4.125W, 3.3V, 1.25A; this NFM-05-5 at 5W, 5V, 1A; NFM-05-12 at 5.04W, 12V, 0.42A; NFM-05-15 at 4.95W, 15V, 0.33A; and NFM-05-24 at 5.52W, 24V, 0.23A. Mid-range models include NFM-10-3.3 at 8.25W, 3.3V, 2.5A; NFM-10-5 at 10W, 5V, 2A; NFM-10-12 at 10.2W, 12V, 0.85A; NFM-10-15 at 10.05W, 15V, 0.67A; and NFM-10-24 at 10.08W, 24V, 0.42A. Higher-output options include NFM-15-3.3 at 11.5W, 3.3V, 3.5A; NFM-15-5 at 15W, 5V, 3A; NFM-15-12 at 15W, 12V, 1.25A; NFM-15-15 at 15W, 15V, 1A; and NFM-15-24 at 15.12W, 24V, 0.63A. The top group includes NFM-20-3.3 at 14.85W, 3.3V, 4.5A; NFM-20-5 at 22W, 5V, 4.4A; NFM-20-12 at 21.6W, 12V, 1.8A; NFM-20-15 at 14.85W; and NFM-20-24 at 22.08W, 24V, 0.92A.

Is the NFM-05-5 intended for outdoor exposure?

Its operating temperature is specified from -20°C to +70°C, so temperature performance is defined within that range. The provided data does not list an IP rating, so outdoor dust and water protection are not established by these specs.
