One ballast different lampa fluorescent or compact fluorescent lamps ¡E Reduction of inventory costs and flexible processes,since many ballasts that were suited for only one lamp,will no longer be many Automation identification of lamps ¡E All of these lamps are run optimally according to their specifications Warm start of lamp possible in every dimming position ¡E When switched on, the ballast will start the set light value without difficulty in every dimming position ¡E Especially for lighting systems in cinemas,theaters and concert halls this function is a major advantage Dimming range up to <1% of light flux ¡E Voltare-dependent control enables a change of brightness and effective energy savings Throughout the entire range of control Control input 1-10V0.25mA ¡E By means of a current sink 20mA, about 50 of these ballasts can be controlled in synchronism Electric strength ¡E If supply voltage exceeds 350V, the ballast swutches automatically to the lowest dimmer Position which has internally been fixed
