[a]
10 V, 12 V, 13.8 V, 15 V outputs, or “V” input range have standard trim range ±10%. Consult factory for wider trim range.
3.3 V output trim range 2.20 to 3.63 V, 95 V output –50 + 0% trim range.
131% nominal for booster modules.
[b]
[c]
Output voltages of 3.3 V or 5 V incorporate foldback current limiting; For output voltages from 5.2 V to 7.5 V consult factory; All other outputs provide constant current limiting.
