Siemens makes building automation products for KNX. Its range on KNX MORE covers switching actuators, universal and 1-10V dimming actuators, shutter and blind actuators, analog dimming outputs, sensors, a decentralized KNX power supply and connectivity devices. Several of the listed actuators are rated for 120-277 V AC installations.
Check the voltage and load ratings against your project, then add the devices to the project planner.
Frequently asked questions
Why do some Siemens actuators list 120-277 V AC?
Those models are made for installations with 120-277 V supplies. Always check that the rated voltage of an actuator matches the supply in your project before choosing it.
What is a decentralized power supply?
A small KNX power supply placed near the devices it powers instead of in the main distribution board, useful for small lines or line extensions. Check its output current against the bus current of the devices.
What does C load mean on a switching actuator?
It means the contact is rated for capacitive loads such as LED drivers, which draw high inrush currents when switched on.
