Explain working of PIU(Power Interface Unit) in
Telecommunication,

Answer Posted / jile singh

piu(power interface unit) convert 3 phase ac power supply in
230 volt ac with stablised and no surge and interference
effect. piu mostly used in telecom sector for providing ac
supply to all equipment used in shelter and also control dg
and consist a lot of protection and showing alarm indication
and record events upto 500.
