Description of Tridonic LC 19 W 200–350 mA LED power supply
This Tridonic LED power supply from the essence series is designed for in fixture installation in linear luminaires, downlights and architectural fittings. It offers seven fixed current levels, selectable via the three pin DIP switch. This allows easy matching with LED modules with a voltage range of 20–54 V.
The power supply delivers up to 18.9 W with high efficiency up to 85.5%. It helps reduce energy losses in the luminaire and supports stable operation. The output current features low ripple and very good flicker performance. It provides comfortable light quality for offices, retail areas and general lighting.
The compact metal housing in white measures only 180 mm in length and 21 mm in height. The IP20 rating is intended for indoor use inside luminaire bodies or suspended ceilings. The power supply supports class I and class II luminaires. This gives designers flexibility in electrical and mechanical integration.
LED power supply – safety and reliability features
The LED power supply includes a full protection package with overload, short circuit and no load protection. In case of a short on the output the unit switches off. It automatically recovers after removal of the fault, protecting LEDs and wiring.
Temperature protection according to EN 61347-2-13 C5e keeps operation stable in demanding conditions. Lifetime reaches up to 100,000 hours when thermal limits are respected. A five year warranty from the manufacturer confirms the quality level and reliability. This reduces maintenance costs in professional projects.
LED power supply – easy installation and applications
The slim linear shape fits narrow profiles, trunking systems and linear fixtures. Push wire terminals support quick wiring with 0.5–1.5 mm² conductors. The DIP switch allows comfortable current adjustment, always with the mains switched off for safety.
The power supply is suitable for linear fixtures, downlights, ceiling panels and task lighting systems. It also supports DC and pulsed DC operation for central battery systems, within specified limits. This makes it a universal choice for OEM luminaire manufacturers and installers seeking a robust 19 W LED power supply with adjustable current.
