REDRESOR

A semi-commanded rectifier for traction RST 2x 1250/ 1250 type is destined to charge with voltage of variable cc a group of engines of traction with series excitation, the group of engines being formed of two engines type LJE – 108 in series. The semi-commanded rectifier for traction RST 2x 1250/ 1250 transforms the alternative voltage from the secondary of traction of the main transformer of the locomotive in continuous adjustable voltage, by the putting into series of double semi-commanded bridge in economical assembly (RST 2 x 625/ 1250 PDME) with a simple semi-commanded bridge (RST 1250/ 1250 PS) being the functionally equivalent with four rectifier bridges in series.
