Tridonic LC 19/200-350/54 flexC lp SNC4 19W – technical data

LED power supply Tridonic LC 19W – flexible 200–350 mA current

The Tridonic LC 19/200-350/54 flexC lp SNC4 is a compact linear constant current power supply designed for built-in use in luminaires. Thanks to a 3-pin DIP switch it offers seven selectable output currents between 200 and 350 mA, allowing you to match the driver precisely to various LED modules without changing the control gear. The maximum output power of 18.9 W and a wide 20–54 V output voltage range make it suitable for many linear LED boards, downlights and small panels.

SELV – safety and compliance of power supply

The SELV output and compliance with EN 61347-1, EN 61347-2-13, EN 62384 and EN 60598-2-22 ensure a high level of electrical safety and permit use in emergency lighting systems and central battery installations according to EN 50172. The ML300 housing can be earthed, which improves EMC performance and immunity against surges, while the IP20 rating makes the product ideal for indoor use in class I and class II luminaires.

LED power supply 19W – high efficiency and long lifetime

With a typical efficiency of up to 85.5% and a power factor up to 0.98, this Tridonic 19 W LED driver reduces energy losses and mains loading. Optimised thermal design enables a lifetime of up to 100,000 hours when operated within the specified temperature limits (ta up to 60 °C, tc up to 75–80 °C). This results in fewer maintenance interventions, lower operating costs and stable light output of the connected luminaires over many years.

Constant current driver 200–350mA – installation and protection features

The driver is equipped with push-wire terminals for 0.5–1.5 mm² conductors, ensuring fast and reliable connection. For best EMC performance the mains and LED cables should be kept as short as possible and routed separately. The integrated protection package includes short-circuit protection (automatic shutdown and restart after fault removal), overload protection (automatic recovery after load correction) and no-load protection (safe burst mode operation with regulated output voltage when the LED string is open).

Tridonic LED power supply – perfect for linear and downlight luminaires

The LC 19/200-350/54 flexC lp SNC4 has been developed for modern linear luminaires, downlights, area fixtures and spotlights used in offices, hotels, corridors and retail spaces. Slim dimensions of 180 x 30 x 21 mm, 168 mm mounting hole spacing and compatibility with emergency lighting systems make it a versatile choice for luminaire manufacturers and installers. If you are looking for a reliable, efficient and flexible constant current LED driver, this Tridonic model will be an excellent fit for your next LED project.
