DIMMER RACK FOR PLUG-IN DIMMER MODULES
Dimmer Rack is a 19” (483.2mm)
free floor mounting unit made
of MS Sheet and steel sections.
It is capable of accomodating
upto 48 dimmers of 2.5KW or 24
dimmers of 5.0 KW, in plug-in
module configuration. It accomodate
RFI filter circuits, clamp-on
incoming and outgoing power connection
terminals, outgoing MCB’s,
low voltage control power supplies,
cooling fan, etc.
accepts dimmer modules of standard
dimensions, which can be plugged
into any location. The dimmer
rack is provided with six sub-racks,
each suitable for four dimmer
modules of either 2x2.5KW rating.
The dimmer rack and modules are
designed for unobstructed airflow
to cool heat generating Thyristors
and filter chokes. A sub-rack
is also provided for four control
supply modules, one for each phase
of incoming supply and one unit
as spare. Incoming distribution
MCB’s of special operating
characteristic, in the incoming
to dimmer, is provided at the

supply has mains frequency synchronising
circuits which ensure proper synchronisation
when the mains frequency fluctuates.
Centralised mains frequency synchronisattion
help in flicker free lighting
and enables use of plugin module
in any location in the rack. Also
incorporated in the control supply
is a special circuit, which ensures
that maximum voltage acorss lamp
will never exceed the pre-set
value of say 220V, irrespective
of incoming mains supply voltage,
thus ensuring that lamp will not
fuse due to over voltage.
is wired with PVC insulated flexible
copper cables and wires as per
