Figure 6.51 – 300W AC/DC Power Supply
The UPS is installed in the incoming cabling section, below the LV
control section.
The UPS will keep control power to all the critical 120VAC loads
and an extra AC/DC Power Supply that feeds the DC/DC Power
Supply for powering all the drive control components. The main
drive cooling fan, and the AC/DC Power Supply that feeds the
IGDPS boards are not powered from this UPS.
The UPS is programmed for the AS400 communication protocol,
and has several status signals that are fed back to the Customer
Interface Board to allow the control to respond to various conditions
including low batteries, loss of input power, UPS on bypass, etc.
