TCI SIRIO 150/300-1050mA Direct Current Power Supply with Dip-Switch

The TCI SIRIO 150/300-1050mA is a professional direct current power supply with integrated Dip-Switch, designed by TCI for high-power LED lighting systems in indoor environments. Its multi-power architecture makes it one of the most versatile solutions for professional lighting installations demanding precision and long-term reliability.

The ability to select a constant output current from 300 to 1050 mA via Dip-Switch allows this LED driver to adapt to a wide range of system configurations, streamlining electrical design and eliminating the need for additional components. It is the preferred choice for lighting professionals working in high-end commercial and residential projects.

Main technical features

The power supply operates at a rated input voltage of 220-240V and provides 16 selectable constant current profiles, from 50W/300mA to 150W/1050mA, with output voltage ranging from 70 to 165V depending on the selected configuration. The regulated current is guaranteed within ±5% tolerance, including temperature variations. It features an auxiliary output 12V max 100mA and active PFC. Opposite terminals accept cables up to 2.5 mm²/AWG13, with strain relief for cable diameters between 3 and 8 mm. The compact footprint measures 240 x 40 x 59 mm, with a PVC housing and IP20 protection rating.

Safety and protections

Rated Insulation Class II, the driver provides protection against electric shock from both direct and indirect contact. Integrated protections cover overtemperature, short circuit, mains overvoltage and overload, with thermal protection type C.5.a for safe and continuous operation.

Applications

Designed for professional LED installations in indoor environments such as retail spaces, showrooms, offices and exhibition areas, where precise constant current management is required for LED strips, modules or high-power spotlights.
