Central office Interface A
Measured as per recommended set-up. 150 mV pk-pk for EXB50-48S12J.
di/dt = 0.1 A/µs, Vin = 48 Vdc, Tc = 25 °C, load change = 0.5 lo max. to 0.75 lo
max. and 0.75 lo max. to 0.5 lo max.
The EXB50 meets level A and level B conducted emissions only with external
components connected before the input pins to the converter.
Recommended input fusing is 3.15 A HRC 200 V rated fuse on the 48 V.
This product is only for inclusion by professional installers within other
equipment and must not be operated as a stand alone product.
Simulated source impedance of 12 µH. 12 µH inductor in series with +Vin.
Start-up into resistive load.
Maximum output deviation is 10% inclusive of trim.
