MV3000 Air Cooled DELTA Switched Mode Power Supplies (SMPS)
Page 31
2.7 SWITCHED MODE POWER SUPPLIES (SMPS)
Units covered: See Table 2–14.
The DELTA SMPS, shown in Figure 2–5, is mounted on the front of each transistor module. It provides power to
the control electronics of the transistor module and for the MV3000e controller. The SMPS derives a supply
from the drive d.c. link, via a connector on the associated transistor module.
There are several versions, offering different operating voltages, or enhanced d.c. link monitoring.
Power to the control electronics is maintained during a temporary loss of supply.
