DALI dimmableelectronic ballastsDALI is the abbreviation for „Digital Addressable LightingInterface“ - The new standard for controllable lighting systemsAs a leading manufacturer of Electronic Ballasts and initial member ofthe AG DALI, HÜCO has contributed to developing a new standard forlighting control.This new standard provides more comfort and flexibility for lighting systemsand at the same time reduces system costs. The function ofDALI ballasts is superior to the analog (1-10 V) controlled electronicballasts. Despite the parallel wiring of the DALI electronic ballasts, theycan be controlled singly (switching on and off directly via the control linewithout additional relay) and can be combined in banks and scenes.In addition, DALI ballasts offer the possibility of checking the operatingcondition of the lamp and the electronic ballast.Examples of circuits fordimmable ballastsWiring plan for smaller configuration with manualpotentiometer. The number of electronic ballasts in the configurationdepends on type of manual potentiometer.1...10V vs. DALI summaryAddressable individuallyGroup settingScene settingIntegrated system switchingStandard operationTwo-wire controlIsolated interfacePolarity independ interface1...10VDALIWiring plan For larger configuration with additionalsignal amplifier. The number of electronic ballasts in the configurationdepends on type of signal amplifier.The DALI Standard has now been included in the ballast norm IEC60929(E) and therefore facilitates the operation of ballasts from differentmanufacturers at the same time in one control system.Initially DALI, was conceived as a ‚stand alone‘ solution but subsequentlyit has been developed to be integrated in other building managementsystems via the relevant interface. (EIB, LON etc.)DALI ballasts are based on the tried and tested reliable technology ofanalog ballasts. This led to 100% compatibility and the adherence ofthe DALI standards acc. to IEC 60929(E). HÜCO DALI ballasts regularlyundergo rigorous testing to ensure compatibility with requirementsof the standard.Important product characteristics of HÜCO DALI ballastsDimming each device with one potentiometer• Microprocessor controlled• DALI interface with extended over-voltage immunity• Multipower technology (one electronic ballast suitable for differentlamps)• very compact shape• energy-saving (energy class EEI = A1)• flicker-free dimming from 100% to 3%• optimal lamp operation by HLC technology (HÜCO lamp control)• warm start of the lamp and operation acc. to EN 60929• Fulfills requirements of the new EN 61347 standard (previouslyEN60928)• ENEC approved• 3 years warrantyPotentiometer0-150-220 kΩ logNotice:The maximum quantity of dimmable electronic ballasts dependson: the capacity of the automatic fuses and on the capacity ofthe relays.www.hueco.com 99
