Public lighting regulation cabinets ELREM PRO-RJRx equipped with three-phase electronical (IGBT) lighting regulator  of new generation emReg - R 3x400V and transformer TRRn 3x400/42V ,are designed for switch&distribution and three-phase coupled, contactless and continuous/leveled regulation of voltage/lighting flux on public lighting installations realised with HID (high intensity discharge-HighPressureSodium, metal-halide) lamps. Fan-out capacity is 1-6 three-phase cables for street lighting and 1-3 auxiliary  outputs for various consumption (traffic signs, advertising panels etc.)

                                  -continual in standard range from 50% (60% for metalhalide) to 100% of relative intensity

                                  -reduced intensity operation intervals are programmable and adjustable                                                                             -user can adjust parameters by means of interactive man-machine interface of cabinet-                                              controller
