LED power supply for downlights and panels – applications
This LED power supply from the Tridonic essence series is designed for modern luminaires. It is ideal for downlights and spotlights in retail spaces. It also works very well with panel and area luminaires in offices or schools. The compact housing allows mounting inside the luminaire or as an independent power supply. Optional clip on strain relief supports safe cable fixing for ceiling installations.
The power supply supports luminaires of protection class I and II. This makes it suitable for many professional lighting projects. Low output ripple helps to reduce visible flicker on the LED modules. That improves comfort for users in workplaces and educational buildings.
LED power supply 17W 250–400 mA – flexible setup
The output current of the power supply is adjustable by DIP switch. You can select 250, 300, 350 or 400 mA depending on the LED module. This allows precise matching of the power supply to the required current. Maximum output power at 400 mA is 16.8 W with high efficiency. Lower current settings reduce power and the thermal load on the components.
The fixed current output provides stable supply for LED modules. Typical efficiency up to 85.5% helps to minimise energy losses. A high power factor up to 0.97 reduces reactive power in the installation. That is important in larger commercial projects with many luminaires.
LED power supply with full set of protections
The unit includes comprehensive protection features for safe operation. It offers overload, short circuit and no load protection on the output. Over temperature protection limits current or temporarily switches off when overheating. After the fault is removed the power supply returns to normal operation automatically.
The polycarbonate housing has IP20 rating for indoor dry environments. The product complies with relevant EMC and safety standards for lighting. It is tested for up to 50,000 switching cycles and long lifetime. Together with five year warranty it is a reliable choice for installers and lighting designers.
