O66-3340-3BK - Luminaires of “O” type maintain the control of luminous flux level according to 0-10 V control interface. Due to high-quality components and professional approach to design, this model provides smooth luminous flux regulation from zero to 3300 lm during the whole operation period.

0-10 V control interface allows using luminaires in the premises, where the change of the illumination level and flexible zoning of the territory are required. The control is carried out using only 2 additional conductors that can be connected to many luminaires simultaneously and control their brightness. To use the 0-10 V interface, it is sufficient to install the relevant regulator or potentiometer. If the control signal is absent, the luminaire operates with nominal brightness. The pulse-duration modulation may be used as a control signal.

Unique circuit solutions ensure smooth regulation of the smoothed direct current via LEDs, which, unlike other common regulation methods, excludes the possibility of increasing the level of luminous flux pulsation when adjusting the luminaire brightness.

LEDs of DURIS E series by OSRAM Opto Semiconductors provide high-quality luminous flux in full compliance with the stated parameters including both light spectrum components and luminous flux stability throughout the whole operation period.

Metal case guarantees reliability and long lifetime. Case dimensions ensure the most rational variants in lighting.

Smooth opal diffuser provides uniform light diffusion. This model is recommended for rooms with ceilings height less than 3m. The use of diffuser made of high quality material ensures the absence of its surface yellowing during luminaire operation period.

Driver modification is designed with account of requirements of the Cabinet of Ministers of Ukraine Resolution #992 from October 15, 2012 to LED luminaires, purchased through competitive biddings announced by state organizations.

 LED luminaire by VTN meets the requierements of  TU 27.4-13317508-012:2014, EMC Directive 2004/108/EC and Directive 2006/95/EC (LVD), EN IEC 60598-1:2014, EN IEC 60598-1:2002, EN IEC 60598-2-2:2007, EN CISPR15:2007, EN IEC 61547-2001, EN IEC 61000-3-2:2008, EN 61000-3-3:2012, GOST 17677-82. Warranty period for all LED luminaires is 5 years from the date of sale. Luminaire lifetime - 50 thousand hours.
