SO66-3340-A11 (S-Class «LED-panel») – LED luminaire with an opal uniform diffuser in the design of a LED panel. It is intended for premises where the lighting product design is important. This model supports luminous flux level control via the 0-10 V control interface. Thanks to the use of high-quality element base and a highly professional design approach, this model provides smooth adjustment of the luminous flux from zero to 3300 lm throughout the entire life cycle.

The 0-10 V control interface allows the luminaire to be used in rooms that require changing the level of illumination or flexible zoning of the territory. The control is carried out using only 2 additional conductors, which can be connected to many instances of fixtures at the same time and control the brightness of all of them. To use the 0-10 V interface, it is sufficient to set the appropriate regulator or potentiometer. The luminaire operates at nominal brightness in the absence of a control signal. PWM (pulse-width modulation) can be used as a control signal.

Unique circuitry solutions provide smooth regulation of constant smoothed current through the LEDs, which, unlike other common methods of regulation, eliminates the possibility of increasing the level of pulsation of the luminous flux when adjusting the brightness of the luminaire.

Metal case is characterized by ІР54 that guarantees dust and moisture protection, reliability and long lifetime. Case dimensions ensure the most rational variants in lighting.

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

Photobiological safety – the luminaire meets the requirements of photobiological safety standard for the use of LED-based products. According to EN IEC 62471:2017 it belongs to the exempt risk group, which applies to lighting fixtures that do not provide optical hazards, including for a long, unlimited period of use.

LED luminaire by VTN meets the requirements of TU U 27.4-13317508-012:2014, EMC Directive 2014/30/EU and Directive 2014/35/EU (LVD), EN 60598-1:2015+A1:2018, EN 60598-2-2:2012, EN IEC 55015:2019/A11:2020, EN IEC 61000-3-2:2019, EN 61000-3-3:2013, EN 61547:2009
Warranty period for all LED luminaires is 5 years from the date of sale. Luminaire lifetime – 50 thousand hours.
