Power Distribution - GE Mark VIe System Manual

1.5 Power Distribution

The Mark VIe and Mark VIeS control systems are designed to operate on a flexible, modular selection of power sources. The
power distribution modules (PDM) support 115/230 V ac, 24 and 125 V dc power sources in many redundant combinations.
The power applied is converted to 28 V dc for operation of the I/O packs, controllers, and switches.
Note Refer to For more information on the IONet switches, refer to the Mark VIe and Mark VIeS Control Systems Volume
II: System Guide for General-purpose Applications (GEH-6721_Vol_II), the chapter PDM Power Distribution Modules. The
JPDS, JPDM, JPDG, or JPDC core power distribution board allows for the optional attachment of a PPDA I/O pack for
system feedback.
The PDM can be divided into two substantially different categories, the core distribution system, and the branch circuit
elements. They serve as the primary power management for a cabinet or series of cabinets. The branch circuit elements take
the core output and fan it into individual circuits for consumption in the cabinets. Branch circuits provide their own feedback
mechanisms, which are not part of the feedback provided by the PPDA I/O pack. The wide variety of power distribution
components available for use with the Mark VIe and Mark VIeS control systems allow for a flexible and scalable power
distribution solution.
