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-10-12 for a 12V PLC accessory or control circuit?

This model provides 12V constant voltage at up to 0.85A, with 10.2W available output power. That makes it suitable for small 12V control, PLC accessory, relay, or sensor loads that stay within those ratings.

Is the NFM-10-12 a fit for compact 12V automation hardware?

Yes, for compact 12V automation electronics that require a fixed 12V supply and no more than 0.85A. Its 65.0 x 45.0 x 22.0 mm dimensions are useful where the power module needs to fit inside a smaller enclosure.

Would the NFM-10-12 work for low-power 12V monitoring or alarm electronics?

It can support low-power 12V monitoring, alarm, or interface electronics when the total load is within 10.2W. The constant-voltage operating mode is appropriate for devices designed to run from a regulated 12V rail.

Can this 12V power supply be used in equipment sold internationally?

The 85-264VAC input range supports a wide span of AC input conditions. That makes it practical for 12V equipment intended for use across regions with different mains voltages.

How does the NFM-10-12 compare to other NFM series options?

The lower-power models include 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 NFM-05-24 at 5.52W, 24V, 0.23A. The 10W group includes NFM-10-3.3 at 8.25W, 3.3V, 2.5A; NFM-10-5 at 10W, 5V, 2A; this 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 models 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; and NFM-15-24 at 15.12W, 24V, 0.63A. The 20W models are 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.

Can the NFM-10-12 be used in environments with variable temperatures?

The specified operating temperature range is -20°C to +70°C. The provided specifications do not include an IP rating, so protection against water and dust ingress is not specified here.
