DECS-250N bridge operating power configuration includes selection of the input voltage range and mode
of operation. These settings are illustrated in Figure 151.
Operating Power Input
AC voltage range A settings for bridge operating power establish the values expected by the DECS-250N.
Modes of Operation
Firing Pulse Mode
Firing Pulse Mode B settings for the bridge operating power establish the number of phases expected by
the DECS-250N.
Single-Phase Selection
Single-phase C settings establish which pair of phases the DECS-250N expects to supply bridge operating
power. This option is disabled when Three Phase is the selected firing pulse mode.
