Note:
1.
Load regulation is measured for an output
change of 20% to 100%.
2.
The outputs of these units may be connected
to provide a 5 VDC, 18 VDC, 24 VDC or
30 VDC output. To do this, connect the load
across the positive (+Vout) and negative
(-Vout) ouputs and float the ouput common.
3.
These units do not require external comonents
to operate, but the use of an input capacitor
(10 µF) may enhance performance in some
applications. For applications requiring lower
output ripple levels, the addition of an output
capacitor (4.7 µF to 10 µF) will typically
achieve good results.
