The worldwide standard for home and building control Universal dimmers for all needs – modular and flexible Innovative products for effective illumination Comprehensive product line The universal dimmers are of very compact 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. 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. 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. Versions for islanding There are also modular universal dimmers N 527 available – optimized for islanding. These modules are suited for use in networks with no synchronous connection to the common network, e.g. in islanding with generators. 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 S uited for all types of resistive, capacitive or inductive loads F ree combination of up to six output modules A ll extension modules can be operated individually C onventional series buttons can be connected for switching and dimming Safe operation Universal dimmers N 527 excel in longevity and safe, continuous operation. They signal via KNX impending overloads, potential short-circuits or the risk of overheating.

Application example Application: Scene control 230 V AC 1 oom unit, e.g. R room controller UP204 Contouch 2 niversal main U module N 527-31 (500 VA) 3 niversal extension U modules N 527-41 (500 VA) To create attractive illumination and an inviting atmosphere in the sales field, the universal dimmers can be set to different dimming levels. This way, the focus can be put on products and exhibits while in other areas lighting can be dimmed to a lower level. This saves energy and directs attention to the more important objects. Using a room operating unit, the dimmers can be controlled via KNX...

Universal dimmers Universal dimmers are dimmers which automatically determine the load type connected to their outputs (resistive, inductive or capacitive) and switch over accordingly to leading-edge phase mode (for a resistive or inductive load such as incandescent lamps or LV halogen lamps with an upstream conventional trans- former) or trailing-edge phase mode (for a capacitive load such as LV halogen lamps with an upstream electronic transformer) 1-channel operation without KNX, control via conventional push- Universal dimmer Combination options for universal dimmers, main modules and...
