The Prisma IP



 48 V DC Rectifier System is specifically 

designed to operate as an integral part of a complete 
distributed power system.  The Rectifier System Power Shelf 
is 2 RU high and mounts in a standard 19” equipment rack.  
Optional 23” rack mounts are also available.  The power shelf 
has slots for up to 3 power rectifier modules.  The rectifier 
module converts 120 or 230 V AC to a regulated DC voltage 
suitable for powering 48 V DC powered products.  Blank 
power shelf modules should be installed in any unused slots. 

 

A full complement of alarm and shutdown features has been 
incorporated into the rectifier module to protect the system in 
the event of a fault condition.  The flexible feature set makes 
the 48 V DC Rectifier System an excellent choice for 
applications requiring modular ac-to-dc bulk intermediate 
voltages, such as distributed power.
