Saber 3412 DC Drive Burden Resistor Selection Guide

This document provides instructions for selecting and installing the correct burden resistor for overload protection on Louis Allis Saber 3412 DC Drives (25HP 240 VAC and 50HP 500 VAC). It explains that the resistor calibrates the current feedback signal and must be matched to motor characteristics (full load amps, HP, voltage) using Table 1, with the resistor housed in a 6CONN connector on the 12SCR Controller PCB.
