Series: PGVG 200 Type: NVG200-18-DC-G emergency light supply units for operating 1 or 2 luminaires with incandescent lamps or low pressure discharge lamps with electronic ballast. Single battery system design in accordance with EN 60598-2-22. Battery: sealed Pb battery. Housing: 960 °C glow wire tested Output: 74W (rated duration 1h) / 31W (rated duration 3h) Length with fixing bar: 580mm Electrical design: Electronic unit with charger, 2 power monitoring units, 2 switch units, DC-DC converter / DC-AC converter, 2 lighting circuits, deep discharge protective shutdown and automatic self monitoring function. 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 the battery. 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. The device shuts down automatically if overheating, overload or a short circuit occurs during battery operation. The standard self monitoring function performs automatic weekly function tests (charger, switch unit and lighting circuits) and annual rated duration tests (battery capacity). The luminaires are controlled by a self adjusting power management system. A display and foil key show operating states and malfunctions and permit function tests to be triggered manually. A message output can forward group malfunctions to an external alarm system. Battery unit with maintenance free sealed Pb battery, service life: 6-9 years according to EUROBAT. Mechanical design: Battery and electronic units in separate boxes in accordance with EN 50272-2. Battery unit with ventilation slit. Screw-fastened lid, hinged at the side. Wires threaded through cable bushings.
