Universal dimmers for all needs –
modular and flexible
Innovative products for effective illumination
Comprehensive product line
The universal dimmers are of very com-
pact design and have an output of up to
2,000 VA. They have been designed for
use with all kinds of loads and meet all
requirements, regardless of the type of
application, be it in the conventional field
or in KNX networks.
Built-in cost efficiency
Using the modular universal dimmers, up
to five dimmer extension modules can be
connected to a universal main module.
Hence, both the number of bus connections
and the number of bus power supplies can
be reduced. The two inputs also facilitate
operation via conventional buttons.
Combinations make the dimmers
very powerful
The product line includes two universal
main modules delivering a maximum
dimming output of 300 VA and 500 VA
respectively. The universal extension
modules are available in three versions
offering dimming outputs of up to 300
VA, 500 VA and 1,000 VA. In addition,
the dimming output can be increased
to a maximum of 2,000 VA by connecting
in parallel the outputs of two universal
extension modules of 1,000 VA each.
Versions for islanding
There are also modular universal dimmers
N 527 available – optimized for islanding.
These modules are suited for use in net-
works with no synchronous connection to
the common network, e.g. in islanding
with generators.
Safe operation
Universal dimmers N 527 excel in longevity
and safe, continuous operation. They sig-
nal via KNX impending overloads, potential
short-circuits or the risk of overheating.
