Bosch PRA-PSM24 24V Power Supply Module for PRAESENSA System Controller

The PRA-PSM24 power supply module is a compact DIN‑rail mounted power supply, delivering 24 V at up to 10 A continuously. This power supply is an OEM power supply, made for Bosch by Delta Power Supply, as a cost-effective alternative to the PRAESENSA multifunction power supply PRA-MPS3 to power a PRAESENSA system controller or other devices and utilities that need 24 V, in case the additional functions and characteristics of the multifunction power supply is not needed. The PRA-PSM24 power supply can also power Bosch PAVIRO controllers and routers in case no battery backup is needed, as alternative to the Bosch PLN‑24CH12 battery charger and power supply. The PRA-PSM24 is not certified for EN 54‑4 and similar standards.

The mains are supplied via a 3‑pole screw plug that requires the module to be installed by professional installers and mounted in a safe place, without user access.

For fail safe redundancy it is possible to use two 24 V power supplies for one PRAESENSA system controller, one connected to its 24 V input A and the other to input B. In that case, the power supply with the highest voltage will supply the power, the other one is available as backup.
