Test conditions and notes7

1. All parameters NOT specially mentioned are measured at 230VAC input, rated load and 25℃ of ambient temperature.
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. Tolerance : includes set up tolerance, line regulation and load regulation.
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. 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. Touch current was measured from primary input to DC output.
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-15-24 for a 24V PLC I/O module or small automation controller?

It can fit 24V control loads that stay within the unit's 0.63A output current and 15.12W power rating. That makes it relevant for small industrial control electronics that require constant 24V DC rather than higher-current field devices.

Is the NFM-15-24 suitable for powering a 24V sensor or relay interface in an industrial cabinet?

It is intended for constant-voltage 24V output and can support loads up to 0.63A. For low-power sensor interfaces, relay boards, or monitoring modules that stay inside 15.12W, the electrical rating is aligned with that type of use.

Can this 24V power supply be used for embedded or IT equipment that runs on 24V DC?

Yes, if the equipment requires a regulated 24V constant-voltage supply and draws no more than 0.63A. Its 85-264VAC input also suits equipment deployed across sites with different AC mains ranges.

Is the NFM-15-24 suitable for outdoor or harsh-environment use?

The provided specs list an operating temperature range of -20°C to +70°C, but they do not list an IP rating. Based on the provided data, temperature capability is defined, while outdoor or washdown suitability is not established by an IP classification.

How does the NFM-15-24 compare with the other NFM series models?

Within the provided sibling list, the series includes NFM-05-3.3 at 4.125W, 3.3V, 1.25A; 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; NFM-05-24 at 5.52W, 24V, 0.23A; 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 siblings listed are 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; 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 in the provided data; and NFM-20-24 at 22.08W, 24V, 0.92A. This NFM-15-24 sits between the 10.08W 24V model and the 22.08W 24V model in the 24V branch.
