Connecting Power Supplies in Parallel
For parallel operation of power supplies, a few technical details must be observed.
The only Loxone power supply that can be operated in parallel is the Loxone 10a power supply.
Should a power supply be switched off or in the worst case fail, it is necessary to install a diode which protects the secondary power supply from damage caused by an opposite current flow. A Schottky diode can be used for this application . Please do not forget the cooling of the diodes in the form of a suitable heat sink.
- Set the output voltage of the power supply to be slightly higher than 24V in order to account for any voltage drop caused by the diode.
- Make sure that this is the same for all power supplies in the setup.
- Disconnect the connection between pin 1 & 2 from the connector CN201 (black wire).
4.Use the same cross-section and same cable length for optimum load distribution on the output side.
A maximum of 5 DRF-240 power supplies can be connected. Only 80% of each power supply can be used.
