Notes
1 Measured as per recommended set-up. Cin = 270 µF (20 mΩ ESR max,
Cout = 3 x 560 µF (5 mΩ ESR max).
2 Vin = 12 Vdc, Tc = 25 °C, bounded by min/max load specification with
recommended system caps.
3 External input fusing is recommended.
4 Measured with external filter.
5 Start-up into resistive load.
6 Meets levels A and B conducted emissions with external components.
7 This product is only for inclusion by professional installers within other
equipment and must not be operated as a stand alone product.
8 Large value ceramic capacitor located close to the input pins is
recommended (TDK p/N C4532X7R1E106M).
9 Use of additional high quality ceramic output capacitors is recommended
in the end system.
10 TSE RoHS 5/6 (non Pb-free) compliant versions may be available on
special request, please contact your local sales representative for details.
11 NOTICE: Some models do not support all options. Please contact your
local Artesyn representative or use the on-line model number search tool
