Type: NVG200-26-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: 106W (rated duration 1h) / 45W (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 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 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.
