Frequently Asked Questions
Can I use the NFM-05-3.3 for a 3.3V embedded controller or SBC?
This model provides 3.3V constant voltage at up to 1.25A, with 4.125W total output. That suits low-power embedded controllers, SBCs, and logic boards that need a regulated 3.3V rail within those limits.
Is the NFM-05-3.3 suitable for industrial communication or I/O electronics that run on 3.3V?
It can fit 3.3V communication, interface, or I/O electronics as long as the load stays at or below 1.25A and 4.125W. Its constant-voltage output makes it appropriate for equipment designed around a fixed 3.3V input.
Would this work for a compact 3.3V control board inside automation equipment?
Yes, for small 3.3V control or processing boards that do not exceed 1.25A. The compact 58.0 x 45.0 x 19.1 mm size also helps when the power section has limited internal space.
Can the NFM-05-3.3 be used where AC input standards vary by site?
The input range is 85-264VAC, which supports a wide AC input span. That makes it practical for 3.3V equipment deployed across installations using different mains voltages.
How does the NFM-05-3.3 compare with the rest of the NFM family?
In the lower-power group, 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; 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; 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 larger 20W models include 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-05-3.3 be used in indoor panels with temperature swings?
The specified operating range is -20°C to +70°C, so the unit is rated across that temperature span. No IP rating is listed in the provided specs, so enclosure sealing against dust or water is not specified.
