Notes

1 Nominal input voltages are 12 Vdc, 24 Vdc and 48 Vdc.

2 Measured from high line to low line at nominal loads.

3 Measured from full load to no load ( auxiliary outputs at no load).

4 Auxiliary ±12 V load regulation, 15% full load to 100% full load.

Initial: 5 V @ 2.1 A, ±12 V @ 0.6 A.

Final: 5 V @ 2.1 A, ±12 V @ 0.09 A.

Auxiliary ±15 V load regulation, 20% full load to 100% full load.

Initial: 5 V @ 2.1 A, ±15 V @ 0.5 A.

Final: 5 V @ 2.1 A, ±15 V @ 0.1 A.

5 To order a model with reverse polarity inputs, add the suffix ‘-A’ to the

model number, e.g. NFC25-24T05-12-A.

6 A minimum load of 1 Amp is required on the 5 V output in order to

maintain regulation of the auxiliary outputs.

7 A load sharing facility is available, whereby the 25 Watts of power is

available to any single output or any combination of outputs. There are,

however, two prerequisites: the maximum output current may not be

exceeded and the regulation is maintained as per Note 6.

8 Nominal load conditions:

5 V @ 2.1 A, ±12 V @ 0.6 A and 5 V @ 2.1 A, ±15 V @ 0.5 A.

9 The unit will be damaged by the application of a low impedance voltage

source to the remote on/off pin.

10 Maximum case temperature must not be exceeded. Derating may be

extended or restricted depending on available cooling.

11 The ‘J’ suffix indicates that these parts are Pb-free (RoHS 6/6) compliant.

TSE RoHS 5/6 (non Pb-free) compliant versions may be available on

special request, please contact your local sales representative for details.

12 NOTICE: Some models do not support all options. Please contact your

local Artesyn representative or use the on-line model number search tool
