The OPTOTRONIC 20W Dual Dim small form factor (SFF) LED drivers are compact, programmable constant current solutions ideally suited for downlight and residential luminaires. These drivers offer precise dimming capabilities to either 1% or 5%, making them highly adaptable to a wide range of lighting designs and user preferences. Dual Dim functionality allows compatibility with both analog 0-10V controls and multiple phase-cut options for models with 120VAC input voltage, providing versatile control over LED output. The drivers operate across a wide input voltage range of 120-277VAC and support output currents from 250 to 500mA, allowing seamless integration into diverse fixture types. Programming and configuration are facilitated through the OT Programmer software, enabling fine-tuning for application-specific requirements.
The OPTOTRONIC 20W drivers offer full programmability of LED output currents in 1mA resolution, with selectable minimum dimming levels of 5% for this series. Control curves can be configured as logarithmic (default), linear, square (0-10V models only), or soft-linear (0-10V models only), providing smooth and predictable dimming behavior. Additional programmable parameters include AUX output voltage and standby settings for peripheral devices. AUX voltage is adjustable from 4-24VDC with a maximum output current of 100mA and voltage resolution of 1V for voltages below 16V or 2V for voltages 16V and above. The AUX standby setting allows the auxiliary output to remain on or off during standby mode, enabling compatibility with connected devices while maintaining low driver standby power under 0.5W.
The small form factor and compact design of these drivers make them ideal for modern downlight, pendant, and spotlight fixtures in both residential and commercial applications, including hospitality, offices, and healthcare environments. Multiple form factors are available to accommodate built-in installations, although models intended for independent use with strain relief are not included in the SFF series.
Key benefits include natural, flicker-free dimming with smooth brightness transitions and configurable minimum dimming levels. The drivers allow adaptable dimming curves to suit specific lighting requirements, whether dimming to 1% or 5% with OPTOTRONIC models, or to 0.1% with SOLOdrive models. Programmable features extend to dimming level, output current, and dimming curve selection. Supported control protocols include 0-10V, Phase-Cut dimming, DALI-2, and LEDcode2 peripheral devices, offering broad compatibility with existing and emerging lighting control systems.
Performance features of the OPTOTRONIC 20W Dual Dim drivers include universal input voltage operation from 120-277VAC at 50/60Hz, low inrush current, minimal total harmonic distortion (THD), high power factor, and efficient energy use. Hybrid HydraDrive technology, available in ECOdrive and SOLOdrive models, ensures flicker-free performance compatible with sensitive applications such as TV studios and security camera environments, further enhancing their suitability for precision lighting projects.
These drivers provide a compact, versatile, and highly programmable solution for modern LED lighting installations, enabling precise control over dimming, current, and auxiliary output while supporting a wide array of residential and commercial applications.
