Road lighting regulation with and distribution cabinets ELREM PRO-xN are equipped with a three-phase electronical lighting regulator of new generation emReg-R 3x230V and (outline 3 and 4) with regulator emReg-R 3x400V with auxiliary transformer TRRn 400/42V. They are designed for switching and three-phase coupled, contactless and continuous /levelled regulation of voltage/lighting flux on public lighting installations realised with HID (high intensity discharge=high-pressure-sodium, metal-halide) lamps. Fan-out capacity is 1-6 three-phase cables. The cabinet is produced according to the project or the user's demand. The function of regulation of relative lighting flux intensity is continual in standard (extended range on demand) range of 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 (22:00 -6:00, all implemented in processor-controller PRO-CRN with an 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 maximum supplied voltage to regulated installation to an appropriate level, that is, independent of mains overvoltage - which benefits to bulb lifespan tremendously. The regulator has controlled temperature with active two-stage temperature limitation, as well as all neccesary protection: overvoltage suppression and two-stage overvoltage transients suppression by means of draining the exessive energy, very fast over- and short-current active protection (voltage regulator self-initiated and performed cut-off in 10-100us, self reset function, hand-shake protocols with cabinet processor), fault diagnostics and memory, with alarm signal (released by faulty condition or by triggering the highest level of protection) which initiates the automatic bypass function controlled by the cabinet processor. Similar protection is integrated in the 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 demage and failure) and a high level of protection of cabinet and installation equipment. This type of regulation has a neutral respective voltage shape and power-factor of lighting installation. Regulated output voltage is in shape equal to sinusoidal input voltage of the mains, practically unaffected with generated distortion (THDu < 0,2 % ), thanks to PWM regulation and very efficient filtering. Efficacy of the regulation is very good, better than 97%. Switching of the lighting can be various: switching in supply point, remote and locally by means of a photo-relay ( Fs). The standard functions are: -switching on/off by: -photo-relay (auxiliary equipment**) -acc. to control programm in the cabinet-controller PRO-CRN with interactive man- machine interface-digital LCD and functional programable keyboard. Switch on/off function is the reserve mode of operation (acc.to annual sunrise/set table). -relative intensity regulation of lighting: -PWM (pulse-width-modulated) regulation of voltage by series compensated ac switching of auxiliary transformer, phase-coupled (delta) -not-influencing and undependant of the sine-wave shape and power-factor of installation -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 -control and protection of the regulator: -processor- controller of the regulator, with diagnostics and memory of faulty/trip states -active two-level control of temperature in case of overheating -transient overvoltage atenuation and two-stage suppresion through excessive energy drain -very fast active overcurrent and short-circuit protection (self-controlled and self-initiated current limitation and cut-off by regulator in 10-100us interval) -selfinitiated reset, control and protection protocols with cabinet-controller -fault signal (at fault and /or emergency state) which is interrupt demand for immediate contactor override (bypass) of the regulator -control and protection of the cabinet: -cabinet-controller PRO-CRN with diagnostics and memory of faulty/trip states, operation- hourcounters for each intensity - bypass funktion-bypass mode of operation in case of fault or protection tripping -controlled temperature-heating (100W with thermostat) and cooling (filtrated inlet of air and force- ventilated outlet with thermostat), alarm thermostat - active two-level control of temperature in case of overheating (cooling failure) -transient overvoltage atenuation and suppresion through excessive energy drain -fast overcurrent and short-circuit protection, selectivity with distribution fuses -double atenuation (filtering) of harmonic distortions and transients ( THDu < 0,2 % ) -protection system TN-C Standard outline: -for open-air mounting (reinforced polyester cabinet-IP43, grounded metal parts, isolation casing -nominal power outlines: mark x=1 – 3x2kVA; x=2 – 3x4kVA; x=3 – 3x7kVA; x=4 – 3x12kVA Standard delivery scope: -fco production plant Rakitje, tested, packed, loaded, with test protocols, Certficates and Declaration of Conformity -two-year guarantee with standard conditions for our products -service and spare parts in guarantee period and next 7 years The additional(optional) functions are: -regulation localy: -PWM (pulse-width-modulated) regulation of voltage by series compensated ac switching of auxiliary transformer, phase-uncoupled (star) -extended range of regulation (min. 35%) - limitMAX = adjustable limitation of maximal operating output voltage in level 100% - - stabMAX = stabilization of output voltage at level 100% on 230VRMS (or on demand)) - stabREG = stabilization of output voltage at level 100% on adjustable level and automatic adjustment of regulation range - system of protection is made according to design/demand (differetial current relays, magnetic-thermic circuit-breakers, thermic fuses with disconnecting bases etc) The additional (optional) outlines are: -for indoor mounting (steel cabinet with polyurethane or epoxy-coating-IP43, grounded metal parts) -IP54 for all outlines --nominal power outlines: mark x=2a – 3x5kVA; x=3a – 3x10kVA The additional (optional) delivery scope: -free-at-border, tested, packed, loaded, with test protocols, Certficates and Declaration of Conformity -testing of function after mounting and trial operation, issuing of protocols -service on demand during guarantee period -regular service during guarantee period The additional(optional)services on demand: -consulting for designers/consultants, investor technical stuff, maintenance personnel-lecture and practice
