parameter inside the rack, and realizes automatic sound and light alarm in sudden fault.
● Standard RJ45 network management telecommunication interface, which can be easy to realize
remote central monitor.
1.PS250 power supply module
Features
PS250 series power supply is a high-reliability power supply system of latest switch power structure, which has small volume, high efficiency energy conversion, small interference harmonic and large output power characteristics. The input power can be converted into +24DC, +5DC and -5DC and provide to a system rack application module for use. It can be configured two PS250 power supply modules at most inside the rack to operate in the mode of online hot backup.
