The PRA-PSM48 power supply module is a compact DIN-rail mounted power supply, delivering 48 V at up to 5 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 power amplifier in case the additional functions and characteristics of the multifunction power supply are not needed. It is not certified for EN 54-4 and similar standards. Because of its ability to deliver high peak currents, this power supply module can supply sufficient power to a single fully loaded PRAESENSA 600 W power amplifier.
