The HALOTRONIC HTi is a DALI transformer for use with low voltage halogen lamps, and is suitable where you need dimming below 1 %. Highly energy-efficient, it provides short-circuit, overtemperature and overload protection (electronically reversible) and electrical isolation between the primary and secondary sides. It does not allow switching between the electronic transformer and the lamp. HALOTRONIC HTi is suitable for use inside; for effect and accent lighting, object lighting, recessed and surface-mounted ceiling light fittings and for the illumination of spaces such as conference rooms and living rooms. It is also good for shoplighting and restaurant lighting. It consumes little power, yet has a large temperature range, and its protective operation throughout the entire partial-load range promotes lamp life. You can through-wire HALOTRONIC HTi on the primary side.
