LED power supply for linear luminaires and projects
This Tridonic LED power supply LC 35/200-350/121 flexC lp SNC4 is designed for in-luminaire use. It is dedicated to class I luminaires with metal enclosures and linear LED modules. The non-SELV concept allows higher output voltage, so it can feed longer LED strings with stable current and good efficiency.
The power supply operates in a wide mains range, which helps in unstable networks. High efficiency up to 91.5% reduces energy losses and heat inside the luminaire. This improves component lifetime and overall reliability in demanding installations.
LED power supply with adjustable 200–350 mA current
A built-in DIP switch allows quick selection of four output current levels. Available settings are 200, 250, 300 and 350 mA. This flexibility lets one LED power supply type match many linear modules and boards from different brands. Current must be set with mains disconnected for safe handling.
The constant current output keeps light output stable and consistent. Low ripple and compliant flicker parameters support visual comfort in offices, schools and healthcare spaces. It is a good match for downlights, linear systems and panel luminaires.
Tridonic LED power supply – safety and durability
The metal housing facilitates protective earthing of the luminaire. Integrated protections against overload, overtemperature and short circuit secure both modules and power supply. In case of thermal overload, the unit switches off and restarts automatically after cooling.
The declared lifetime reaches up to 100,000 hours, depending on operating temperature. The LED power supply is suitable for central battery systems and emergency installations with DC supply. It is an excellent choice for professional lighting projects in commercial, office and industrial buildings.
