DC supply system

Basic use: power supply of telecommunication devices

Supply system SUNA consists of monitoring unit BNU 85 and max. 4 SMC rectifier module type SMC 320 installed in a 19"cabinet.

Function of monitoring unit is to prevent deep discharge of battery, battery charging control and monitoring rectifier.

Main features of rectifier is good stability of output voltage and current, active PFC and HOT PLUG (under voltage module change).

Optional ETHERNET communication with PC.
