Information about Family

HALOTRONIC PROFESSIONAL HTL is an electronic transformer, dimmable on the leading and trailing edge. It protects from short-circuit, overtemperature and overload (electronically reversible) and has electrical isolation between the primary and secondary sides. Switching between the electronic transformer and the lamp is not permitted. With high levels of energy efficiency, this transformer has many applications, but is particularly good for effect and accent lighting, object lighting and furniture luminaires (recessed and surface-mounted). It is also good for living rooms, conference and event rooms, shoplighting and restaurant lighting. High efficacy means that little power is lost, and HALOTRONIC PROFESSIONAL HTL covers a large temperature range. Protective operation throughout the partial-load range prolongs lamp life, and you can through-wire on the primary side.
