KNX Power Supply
KNX Actuators & Sensors · DIN rail · bus power supply
The bus supply at the head of every KNX installation — a 29 V DC SELV KNX output plus an auxiliary 29 V DC output, with short-circuit protection and a hold-up time that rides through brief mains dips.
- 29 V DC SELV KNX bus output plus auxiliary output
- Short-circuit protected, < 1.6 A continuous
- Rides through mains dips up to 200 ms
- DIN-rail mounting
