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-05-24 for a small 24V PLC or sensor circuit?
This model provides 24V constant voltage with up to 0.23A output and 5.52W total power. That makes it suitable for small 24V industrial control, sensor, or interface loads that stay within those electrical limits.
Is the NFM-05-24 a good fit for low-power 24V automation hardware?
It is intended for low-power 24V devices because its output is fixed at 24V and its capacity is 0.23A. For compact automation assemblies, the 58.0 x 45.0 x 19.1 mm size can also help where board or enclosure space is limited.
Can this 24V power supply be used for a small embedded or industrial interface board?
Yes, if the board requires 24V constant voltage and draws no more than 0.23A or 5.52W. The wide 85-264VAC input range also suits equipment that may be deployed across different AC input standards.
Would the NFM-05-24 work for a compact 24V relay or signal module?
It can work for a compact 24V relay, signal, or interface module when the load remains within 24V, 0.23A, and 5.52W. This is a small-output model, so it fits light-duty 24V applications rather than higher-current 24V hardware.
How does the NFM-05-24 compare with other NFM series models?
Within the series, nearby 5W-class options are 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; and this NFM-05-24 at 5.52W, 24V, 0.23A. Higher-capacity 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. The 15W group includes 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 20W 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-05-24 suitable for outdoor or harsh locations?
The listed operating temperature range is -20°C to +70°C, so temperature capability is specified across that range. The provided specs do not include an IP rating, so dust and water ingress protection are not defined here.
