Bosch PRA-PSM24 24V Power Supply Module for PRAESENSA System Controller
The PRA-PSM24 power supply module is a compact DIN‑railmounted power supply, delivering 24 V at up to 10 A continuously. This powersupply is an OEM power supply, made for Bosch by Delta Power Supply, as a cost-effectivealternative to the PRAESENSA multifunction power supply PRA-MPS3 to power a PRAESENSAsystem controller or other devices and utilities that need 24 V, in case theadditional functions and characteristics of the multifunction power supply isnot needed. The PRA-PSM24 power supply can also power Bosch PAVIRO controllersand routers in case no battery backup is needed, as alternative to the Bosch PLN‑24CH12battery charger and power supply. The PRA-PSM24 is not certified for EN 54‑4and similar standards.
The mains are supplied via a 3‑pole screw plug that requires themodule 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 powersupplies for one PRAESENSA system controller, one connected to its 24 V input Aand the other to input B. In that case, the power supply with the highestvoltage will supply the power, the other one is available as backup.
