Notes
1
Measured as per recommended set-up. 150mV pk-pk for EXB50-48S12.
2
di/dt = 0.1A/s, Vin = 24/48VDC, Tc = 25°C, load change = 0.5 lo max. to
0.75 lo max. and 0.75 lo max. to 0.5 lo max.
3
The EXB50 meets level A and level B conducted emissions only with
external components connected before the input pins to the converter.
4
Recommended input fusing is a 6.3A HRC 200V rated fuse on the 24V
and 3.15A HRC 200V rated fuse on the 48V.
5
This product is only for inclusion by professional installers within other
equipment and must not be operated as a stand alone product.
6
Simulated source impedance of 12H. 12H inductor in series with +Vin.
7
Start-up into resistive load.
CAUTION: Hazardous internal voltages and high temperatures.
Ensure that unit is not user accessible.
