Product Description
The Bosch PRA - PSM24 is a compact 24V power supply module designed for the PRAESENSA system controller. Mounted on a DIN - rail, it continuously delivers 24V at up to 10A. Made by Delta Power Supply for Bosch as an OEM product, it's a cost - effective option for powering the PRAESENSA system controller or other 24V - requiring devices when the extra features of the PRAESENSA multifunction power supply PRA - MPS3 aren't needed. It can also power Bosch PAVIRO controllers and routers without battery backup, serving as an alternative to the Bosch PLN - 24CH12 battery charger and power supply. Note that it's not certified for EN 54 - 4 and similar standards. The power supply connects to the mains via a 3 - pole screw plug, so professional installation in a safe, user - inaccessible place is required. For fail - safe redundancy, you can use two 24V power supplies for one PRAESENSA system controller, with one connected to input A and the other to input B. The power supply with the higher voltage will supply power, and the other acts as a backup. Key features include universal mains input voltage, power factor correction, automatic recovery protection, approval for powering PRAESENSA and PAVIRO devices, and a compact, DIN - rail - mountable design. Technical specs: Dimensions are 121 x 85 x 124 mm, operating temperature ranges from - 25 to 80 Degrees C, operating voltage is 85 - 264 VAC, power factor is 0.90, it has overheat, overload, and overvoltage protection, and weighs 1.10 kg.
Using the Bosch PRA - PSM24 power supply module is quite straightforward. First, make sure you've hired a professional installer to connect it to the mains using the 3 - pole screw plug. It should be installed in a safe place where users can't access it easily. This module is great for powering your PRAESENSA system controller or other 24V - needed devices. If you want fail - safe redundancy, you can use two of these power supplies for one PRAESENSA system controller. Just connect one to input A and the other to input B, and the one with the higher voltage will do the power - supplying job. When it comes to maintenance, keep an eye on the operating temperature. It can work well from - 25 to 80 Degrees C, but extreme temperatures might affect its performance. Also, since it has protection against overheat, overload, and overvoltage, if you encounter any issues, it will try to recover automatically. However, if the problem persists, it's best to contact a professional. Remember, this power supply isn't certified for EN 54 - 4 and similar standards, so use it according to its intended purpose.
