change of 20% to 100%.
2. Dual output 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
-5%/ 1C
(+Vout) and negative (-Vout) ouputs and float Output Power %
the ouput common.
3. For applications requiring lower output ripple 60
levels, the addition of a simple LC filter exter-
nally will provide good results. Using compo-
nent values of 4.7 µH and 4.7 µF will lower 40
output ripple to about 35 mV pk-pk.
