Self-contained supply units L 560 B 237 H 170, MultiDigit colour: grey

Type: NVG200-12-DC-G emergency light supply units for operating 1 or 2 luminaires with incandescent lamps or low pressure discharge lamps withelectronic ballast. Single battery system designin accordance with EN 60598-2-22.Battery:sealed Pb battery. Housing: 960 °C glow wire testedOutput: 50W (rated duration 1h) / 21W (rated duration 3h) Length with fixing bar: 580mmElectrical design:Electronic unit with charger, 2 power monitoring units, 2switch units, DC-DC converter / DC-AC converter, 2lighting circuits, deep discharge protective shutdown and self test and feedback to Multidigit system. Luminaires can be operated in non-maintained or maintained power mode. Separate light inputs and outputs, and control inputs to switch the luminaires in mains operation,per lighting circuit. Battery is charged through input 1.If mains power fails on input 1 and/or input 2, charging is interrupted and output 1 and/or output 2 is fed from thebattery. Once mains power is restored, the device switches back from battery to mains operation after a short delay (10s). During mains operation,the luminaires can be switch individually from non-maintained to maintained power mode using control inputs 1 and 2. An external switch (passive) or external control signal (active) can be used to remotely block switchover from mains to battery operation. Thedevice shuts down automatically if overheating, overload or a short circuit occurs during battery operation. The standard self monitoring function performsautomatic weekly function tests (charger,switch unit and lighting circuits) and annual rated duration tests (battery capacity). The luminaires arecontrolled by a self adjusting power management system.A display and foil key show operating states andmalfunctions and permit function tests to be triggered manually. A message output can forward group malfunctions to anexternal alarm system. Battery unit withmaintenance free sealed Pb battery, service life: 6-9 yearsaccording to EUROBAT.
