Information and conformity LL25SE-DA-120-500 LED driver is suited for built-in usage in Luminaires. In order to have safe and reliable LED driver operation, the LED luminaires will need to comply with the relevant standards and regulations (e.g. IEC/EN 60598-1). The LED luminaire shall be designed to adequately protect the LED driver from dust, moisture and pollution. The luminaire manufacturer is responsible for the correct choice and installation of the LED drivers according to the application and product datasheets. Operating conditions of the LED drivers may never exceed the...

Information and conformity • By default, Direct Control is disabled and LED-Iset terminal is used for current setting. When enabled through the Helvar Driver Configurator, the current is set by the software. • With SELV60 drivers the Direct Control circuit is SELV60 circuit. The components can be rated accordingly. • DALI usage not supported at the same time with Direct Control. Safety isolating control gear with short circuit protection (SELV control gear). Double insulated control gear suitable for built-in use. See more details in Switch-Control & Direct Control User Guide at...
