LED power supply Tridonic for professional luminaires
This LED power supply Tridonic unit is designed for linear, downlight and area luminaires. Constant current operation keeps LED modules stable and ensures consistent luminous flux. The non-SELV concept requires class I luminaires, but gives high efficiency and low power losses.
The power supply delivers up to 39.9 W, which suits many office and retail applications. Its slim linear housing fits narrow channels and compact luminaire bodies. The ML300 case improves thermal behaviour and protects electronics in demanding environments.
LED power supply with selectable output current
The unit includes DIP switches to set four different output currents. You can choose 200, 250, 300 or 350 mA to match various LED modules. Settings must be changed only when mains power is off for safety.
This flexibility reduces stock complexity, because one product covers several current levels. Lighting designers can tune current to required power and LED temperature limits. This helps optimise efficiency, brightness and lifetime of the final luminaire.
LED power supply with complete protection set
The power supply features overload, short circuit and no load protection. In case of short circuit on the output side, it shuts down automatically. After the fault is removed, normal operation resumes without manual reset.
During overload the power supply protects itself, and LEDs may flicker until the load is corrected. In no load mode it keeps the output within a safe voltage range. Surge protection on input and output increases robustness in commercial installations.
