ABB 5SHX1445H0001 SCR control unit module

ABB 5SHX1445H0001 SCR control unit module

transformer if the measured current is above 5A. There are some regulations about wiring

and parameters setting of PMC916measurements according to the measured power

system and the number of the voltage & current transformer. The details are as bellows:

You can choose one current transformer CT(to measure Bphase current), two CT(to

measure A & C phase current), and threeCT.PMC916 can only measure and control

the power parameters of single phase loop when only one CT is in use; when two CT

are used we can gain the third phase current by calculating.
