Figure 5-70. AC Transformer Requirements for PCDPMs
IMPORTANT
DSS/BLF Units, MDPMs, and SLAs always require separate AC transformers. Older PCDPMs, part
no. 550.3014 [PB2548-A], require AC transformers when they are connected to DSS/BLF Units.
PCDPMs do not require AC transformers when they are used for OHVA only or have attached
MDPMs.
