MTN684064 Schneide KNX Bus Power Supply 640mA IP20 For Building Automation Systems
The MTN684064 is a 640mA KNX bus power supply from Schneide's SpaceLogic REG-K series, engineered specifically for medium-sized KNX building automation systems. This core power component integrates dual key features: integrated bus decoupling circuit and one-touch bus reset, balancing power supply stability with engineering maintenance efficiency.
It delivers stable DC30V KNX bus voltage with maximum load capacity of 640mA, supporting up to 128 conventional KNX smart devices in parallel. The built-in decoupling circuit effectively isolates power supply from bus signals, eliminating KNX communication packet loss caused by grid fluctuations. The dedicated bus reset button enables quick recovery of faulty buses and devices, significantly reducing commissioning and maintenance costs.
Featuring 35mm standard DIN rail mounting and compact 4 TE design (≈72mm width), it fits seamlessly into electrical cabinets. With AC 92-253V wide voltage input, it is compatible with global power grid standards and complies with EN 50090 KNX international standard.
