Type: NVG200-90-DC-G Emergency lighting supply units for operating 1 or 2 lights with incandescent lamp or low-pressure discharge lamp with electronic ballast. Designed according to the single battery system in accordance with DIN EN 60598-2-22. Battery: sealed Pb battery Output power: 200 W (operating time 1 h) 190 W (operating time 3 h) Length with mounting rail: 745 mm Housing glow wire tested at 960 °C Electrical design: Electronic part with charging device, 2 mains monitoring devices, 2 switching devices, DC-DC converter or DC-AC converter, 2 lighting circuits, deep discharge protection shutdown and automatic self-monitoring. Operation of the lights in standby or permanent mode. Separate light inputs and outputs as well as control inputs for switching the lights in mains operation for each light circuit. The battery is charged via input 1. If the mains supply fails at input 1 and/or input 2, charging is interrupted and output 1 and/or output 2 is fed from the battery. When the mains supply returns, the device switches back from battery to mains operation with a delay (10 s). In mains operation, the lights can be switched individually from standby to permanent operation via control input 1 and control input 2. A remote switching input enables switching from mains to battery operation to be blocked via an external switch (passive remote switching) or an external control signal (active remote switching). In the event of overtemperature, overload or short circuit in battery operation, the device switches off automatically. The standard self-monitoring automatically carries out weekly function tests (charging device, switching device and light circuits) as well as annual operating time tests (battery capacity). The lights are controlled by a self-adjusting power monitor. A display and a button in foil form show operating states and faults or enable a function test to be triggered manually. A collective fault can be forwarded to an external reporting device via a signal output. Battery part with maintenance-free, sealed Pb battery, service life 6 to 9 years according to EUROBAT. Mechanical design: Battery and electronic parts are in separate housings according to DIN EN50272-2. Battery part with ventilation opening. Housing cover screwed on, can be folded to the side. Cable entry via cable bushings.
