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-15-5 for a 5V single-board computer or embedded controller?

It provides constant 5V output up to 3A, with a 15W rating. That fits many embedded control boards and compact computing devices that need a regulated 5V rail within those current and power limits.

Is the NFM-15-5 suitable for 5V industrial logic or HMI support electronics?

It can support 5V DC electronics that require no more than 3A. For low-voltage control logic, panel electronics, or support circuitry that stays within 15W, the output profile is consistent with that type of load.

Can this model power 5V USB-class or peripheral electronics inside equipment?

It is appropriate for 5V constant-voltage loads up to 3A when the equipment is designed around a 5V DC supply. The 85-264VAC input range also helps when the same equipment platform is used across different AC input regions.

Is the NFM-15-5 rated for outdoor conditions?

The provided operating temperature range is -20°C to +70°C, so temperature performance is specified. The provided specs do not include an IP rating, so outdoor exposure suitability is not confirmed by the product data here.

How does the NFM-15-5 differ from the other NFM family options?

In the 5V branch of the provided sibling list, NFM-05-5 is 5W at 5V and 1A, NFM-10-5 is 10W at 5V and 2A, this NFM-15-5 is 15W at 5V and 3A, and NFM-20-5 is 22W at 5V and 4.4A. The same family also includes NFM-05-3.3 at 4.125W, 3.3V, 1.25A; NFM-05-12 at 5.04W, 12V, 0.42A; NFM-05-15 at 4.95W, 15V, 0.33A; NFM-05-24 at 5.52W, 24V, 0.23A; NFM-10-3.3 at 8.25W, 3.3V, 2.5A; NFM-10-12 at 10.2W, 12V, 0.85A; NFM-10-15 at 10.05W, 15V, 0.67A; NFM-10-24 at 10.08W, 24V, 0.42A; NFM-15-3.3 at 11.5W, 3.3V, 3.5A; NFM-15-12 at 15W, 12V, 1.25A; NFM-15-15 at 15W, 15V, 1A; NFM-15-24 at 15.12W, 24V, 0.63A; NFM-20-3.3 at 14.85W, 3.3V, 4.5A; NFM-20-12 at 21.6W, 12V, 1.8A; NFM-20-15 at 14.85W in the provided data; and NFM-20-24 at 22.08W, 24V, 0.92A. This makes the NFM-15-5 the mid-range 5V option by output current.
