Voltage Adjustment Factory set on standard units. However, optional potentiometer adjusts voltage from 4.7 V to OVP point (6.2 V nominal) on the +5 V output. Note: output #1 must not be more than 1% below nominal to achieve full output voltage range on output #2. Output regulation limits in some models may be exceeded when the main output is adjusted beyond +/- 1% of nominal voltage. See output ratings chart for additional notes and conditions.
