Meanwell KNX Series

The Meanwell KNX System

As our everyday lives have become more and more fast-moving and our consumer goods are subject to a shorter lifespan, the change to new technologies in our homes is rather faltering. Smartphones and cars, for example, are developed from scratch every year because their lifespan is limited.
However, our own four walls last for decades, if not centuries, and therefore do not always go hand in hand with the changing times. But with the Meanwell KNX system this is over.

The key to an intelligent building lies in the various interlinked sensors and actuators and their interaction. A so-called bus system is used for this purpose. Here, each sensor and actuator communicate with each other and does not have to pass the signal through a distributor.

Here is a short list of sensors that give information to the bus:
 

  • Light switch
  • Dimm switch
  • Motion detector
  • Presence detectors (detect whether a person is in the room even without movement)
  • Window and door contacts (safety applications, heating control)
  • Doorbell button on the front door
  • Consumption meters for water, gas, electrical energy, quantities of heat
  • Overvoltage sensors
  • Temperature sensor for indoor and outdoor air
  • Temperature sensors in heating and hot water circuits
  • Modules for preselecting the target room temperature



Example:
The motion detector informs the passageway lighting that someone has entered the room and the room thermostat control that there is nobody left in the room and that it can slightly reduce the temperature in the room..

Why KNX ?

The number of bus systems on the market is diverse and they certainly have their advantages and disadvantages, but no bus system is supported by as many manufacturers as the Meanwell KNX system.
 

  • All well-known brands in the industry support and promote the KNX system.
  • KNX has been specially developed for electrical installation
  • Over 7035 KNX certified product groups are currently available
  • KNX is standard in Europe, China and the USA (ANSI/ASHRAE135)
  • CENELEC (EN 50090), CEN (EN 13321-1), ISO/ IEC (ISO/IEC 14543-3), GB/T (GB/T 20965) US

Members in 33 different countries provide standardized products for the Meanwell KNX system.
 

Departure - the KNX bus

There is hardly any other bus system that supports as many manufacturers as the KNX bus. Das KNX-Netzteil benötigt eine Spannungsversorgung von 24V Nennspannung. With KNX TP, these are routed on a two-wire cable..
The KNX power supplies feed in slightly more than the nominal voltage in order to minimize or even prevent power losses. The bus couplers work without any problems up to the lowest voltage of 21V.
The CSMA / CA (Carrier Sense Multiple Access / Collision Avoidance) access method prevents data loss during collisions.
The KNX power supply follows the standards DIN EN 50090, EN 13321-1 / 2 and ISO / IEC 14543-3.
 

Advantages of KNX

It used to be very time-consuming to find a system for the entire control due to the different electrical cabling. Therefore, the KNX power supply offers a manufacturer-friendly installation form for arbitrary communication between various forms of control.
This enables a system that is relatively easy to integrate, even in highly complex buildings.

Further advantages of the Meanwell KNX system:
 

  • Energy saving and thus reduction of operating costs
  • Comfort gain
  • Facilitation in old age
  • Future-proof and flexible installation
  • Safety (presence simulation, alarm on attempted break-in, defrost alarm of freezer, panic button with message via telephone, etc.)
  • Value of the real estate increases for rental or sale


For a KNX system, a KNX power supply is required and this can not be replaced by a conventional power supply.
