All dimensions are in inches Figure 2 III Regulation With Remote Sense Pin D +Vo + A HS DC-DC Converter +S Load C -S twisted pair Figure 3 F -Vo The 848HS provides regulated outputs at the output terminals. When there is a large current and/or the output cable is of excessive length (longer than 6 feet), the voltage at the end of the cable may be noticeably lower than at the terminals. The converter can compensate up to 0.75V of voltage drop through remote sense terminals.
