Conversion modules
EMEL
A conversion module is required for a conventional fluorescent
mains luminaire when it is powered from a Central Power Supply
System for emergency lighting use. This provides fail-safe
emergency operation from the CPS supply upon failure of the
local lighting circuit whilst retaining the switchable function of the
luminaire under mains healthy conditions.
The MDG inverter module has been designed to efficiently operate
4 – 100 watt 4-pin fluorescent lamps, from 50 volt or 110 volt AC/DC
Central Power Supply Systems.
Features and benefits
l Ideally suited for individual local circuit failure monitoring via the
connection of an unswitched supply
l Incorporates an integral five pole relay which disconnects the normal
mains lighting ballast from the lamp when the monitored 230/240 volt
mains supply is disconnected
l A delayed energy relay prevents the automatic protection circuit of the
electronic ballast sensing an open circuit condition, in emergency test
mode, thus enabling the lamp(s) to restrike without having to re-set
the switched supply
l Electrical connections are made via screw terminals
l Remote boxes available where integral mount is not possible
Specifications
l 220 – 240V AC, 50Hz

CE marking & warranty
A modified luminaire must be
compliant with the Electro-
Magnetic Compatibility (EMC)
and Low Voltage (LV) Directives,
and carry a CE mark to signify the
compliance.
The company modifying the
general luminaire is legally
responsible for the re-certification
of the complete unit after
modification.
In addition, the warranty provided
by the mains manufacturer will be
invalidated by the modifications.
Conversion service
Emergi-Lite offers a specialist
conversion service backed by the
highest level of expertise, from a
number of strategic Conversion
Centres in the UK.
Emergi-Lite is registered under
ICEL1004 for luminaire conversion.
Specifying the conversion service
to be performed by Emergi-
Lite ensures full compliance. In
addition, the warranty provided
by the mains manufacturer is
taken over by Emergi-Lite and
provides complete peace of mind.
Note: Luminaires to be converted
to emergency must themselves
carry a CE mark to be considered
suitable for conversion.
