Bosch PRA-PSM48

PRA-PSM48 Power Supply Module 48V

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.

Compact DIN‑rail mounted power supply, delivering 48 V at up to 5 A continuously, for powering one fully loaded PRAESENSA 600 W amplifier. Because the long term effective power consumption of the amplifier is much lower than the short term burst power consumption, related to the crest factor of speech and music, this power supply is sufficiently powerful.

• Universal mains input with power factor correction to maximize the amount of power that can be taken from a single phase power distribution network.
• The mains is 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.
• Adjustable output voltage, 48 to 56 V, of which the range 48 to 50 V can be used because the PRAESENSA power amplifiers are tolerant up to 50 V.
• For fail safe redundancy it is possible to use two 48 V power supplies for one amplifier, one connected to its 48 V input A and the other to input B. In that case the amplifier load will be shared by both power supplies, even if the supply voltages are adjusted to be slightly different.

• Universal mains input voltage
• Power factor correction
• Protection with automatic recovery
• Approved to power a PRAESENSA 600 W amplifier
• Compact and DIN‑rail mountable
