Nominal input voltages are 12 Vdc, 24 Vdc and 48 Vdc.
Measured from high line to low line at nominal loads.
Measured from full load to no load ( auxiliary outputs at no load).
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
at http://www.artesyn.com/powergroup/products.htm to find a suitable
alternative.
