Road lighting regulation swith and distribution cabinets ELREM PRO-1(2) are equipped with regulators of type elReg NAV-3. They are realized as  independent devices for switching, regulation of lighting intensity and distribution for road lighting installations with high pole with reflectors type of installation (16m for 6 reflectors and 24m for 14 reflectors), with lamp-gears (ballast and condensator) situated in the cabinet. Except for the road (motorway) lighting, the cabinet can supply other systems - active traffic signalization, video-surveillance etc.                                                                                                 Road lighting regulation swith and distribution cabinets ELREM PRO-3 are equipped with regulators of type elReg NAV-3 & elReg NAV-4. They are realized as  independent devices for switching, regulation of lighting intensity and distribution for road lighting installations with standard poles with luminaries type of installation, with lamp-gears (ballast) situated in the luminary and power-factor capacitance  situated in the cabinet. Except for the road (motorway) lighting, the cabinet can supply other systems-active traffic signalization, video-surveillance etc.

             The function of regulation of relative lighting flux intensity is continual in standard (extended range on demand) range 50%( 60% for metalhalide) -100% of relative intensity, or (on demand) with three discrete levels 100%,75%,50% with smooth level-changing with programmed intensity reduction intervals adjustable by the staff, all implemented in processor-controller PRO-CR with interactive man-machine interface-digital LCD and a functional programmable keyboard. There is a function of adjusting the relative maximal level of voltage as 100% level (option- limitMAX), thus conditioning the maximal supplied voltage to regulated installation to apropriate level, that is independent of mains overvoltage - which benefits to bulb lifespan tremendously.

             The regulator has controlled temperature with active power limitation; as well as overvoltage transients suppression by means of draining the excessive energy, very fast over - and short-current passive protection (ultra fast fuses-aR/gR characteristics), fault diagnostics and memory, with alarm signal (released by faulty condition or by triggering the highest level of protection) which initiates automatic bypass function controlled by cabinet processor PRO-CR (self-initiated and externaly triggered automatic bypass function). Similar protections are integrated into cabinet switching equipment with adequate capacity and selectivity. This very high degree of protection pays itself by securing the constant functionality and supply of the lighting installation (uninterrupted and continous operation of facility in case of damage and failure) and a high level of protection of cabinet and installation equipment.

             This type of regulation is not of neutral  respective voltage shape, but not affecting the power factor of lighting installation, except for the neccessity of repositioning of the compensation capacitances. The power factor compensation of pure inductive loads in regulated installation is obligatory infront of the regulator of type elReg, and thus realized as a three-phase compensation block.  Regulated output voltage is in shape similar to sinusoidal input voltage of the mains, affected with generated distortion in allowed intensity (EMC conformity).                                                                        Efficacy of the regulation is very good, better than 98%. Switching of the lighting can be various: switching in supply point, remote and locally by means of photo-relay ( Fs). In the remote control operation, the processor PRO - CRr is used.

             Effects of regulation are: up to 40% of saved energy and 50 to 100% of lamp maintenance cost. Durability and reliability of lighting installation is enhanced. This type of cabinet is the mostly used  type in operating installations at motorways in Croatia.
