3.1 Introduction for KPEC series ATS cabinet
This is an open-loop (or delayed switching, optional) general purpose ATS cabinet (see fig.3-1,
ATS control function is inbuilt at the KPD100 intelligent controller). It will never power on two supply
lines simultaneously. The grid line works with a generator set (emergency power supply) as
standby power and loads connect to the ATS common terminal (see fig.3-2). The controller
monitors voltage and frequency range tolerable to the power supply and controls the transfer switch
to switch between power supplies automatically. Normally, the loads are supplied by grid (see fig.
3-3). When the grid supply is off, the loads will be switched to be supplied by generator set (see
fig.3-4). As the grid supply recovers, the loads will be switched back to grid.
