Check that the power supply matches the linear lighting and control equipment, with the assortment primarily using 24V DC constant-voltage drivers for LED tape and control modules. For DALI applications, verify that the supply and line interface provide the required approximately 21.9V DC output, and select a wattage rating that supports the connected load.

Depending on the model, linear lighting power supplies support forward- and reverse-phase dimming, including ELV, MLV, and TRIAC, while some higher-power units also support 0–10V, 1–10V, 10V PWM, and potentiometer control. For color-changing or tunable lighting, DMX, DALI, and Zigbee control methods can be used with the appropriate gateway, decoder, or control module.

For indoor or low-voltage linear lighting, consider a 24V DC constant-voltage power supply with a low-profile enclosure, knockouts, and separate line-voltage and low-voltage wiring compartments to simplify installation. For outdoor or damp locations, select a power supply with a listed wet-location rating and protective features such as short-circuit, overload, and over-temperature protection, while DIN rail mounting can support organized installations with compatible control equipment.

Use a DIN rail-mounted power supply for a linear lighting system when you want to install the power supply inside a structured electrical or low-voltage enclosure alongside gateways, control modules, or other DIN rail equipment. It provides 24V DC power in a compact, organized format, but confirm that its output capacity matches the lighting load and connected control equipment.
