FUNCTIONAL DESCRIPTION:

DS2020PDMAG3 is a Power Distribution Module manufactured and designed by General Electric as part of the Mark V Series used in GE Speedtronic turbine control systems. For each rack and terminal board in the Mark VI system, the Power Distribution Module (PDM) supplies 125 V dc and 115 V ac (or 230 V ac). In systems that employ remote I/O cabinets, there is a second version of the PDM for the control cabinet.

OPERATION:

  • Power filters are used to enter the PDM with the 125 V dc and 115/230 V ac power supplied by the customer. One or two ac/dc converters that output 125 V dc are connected to the ac power by cables.
  • In order to create a backup power supply, this dc voltage is then cabled back into the PDM and diode linked to the primary dc power. The terminal boards and VME racks receive this power distribution.
  • The ac/dc converters can handle either 115 V or 230 V ac. For operation at 115 V or 230 V, the transformer cable must be inserted into either JTX1 or JTX2.
  • The PDM is used to gather diagnostic data, which is then linked to a terminal board installed on a DIN rail. After that, a cable travels through J301 to the VCMI in rack "R"
  • The relay terminal boards are wired and fused with the ac feeders, J17–20. The protection modules, TRPG, TREG, and TRLY are wired with 125 V dc feeders that are fused.
  • A control power filter (CPF), which reduces EMI noise, is used to feed the PDM to the boards in order to assure a noise-free supply.
  • Before being fused and cabled to the TBCI boards, power to the contact inputs first goes via TB2, then through resistors R3 and R4, then through TB2. An excitation voltage of 125 V dc is used for contact inputs.

DIAGNOSTICS:

A resistance divider network lowers the 125 V dc to the signal level so that it may be monitored. Two AC sources, the battery voltage, and the fuses in the feeders to the relay output boards are among the other things checked. This diagnostic information is cabled to the VDSK board in the control cabinet and subsequently to the VCMI after being monitored by the VCMI in the interface cabinet.

CONFIGURATION:

There are jumpers on TB1 and TB2. On TB3, resistors are placed to lower the 125 V dc to 1.82 V dc for bus monitoring. For systems with an external ground reference, jumper BJS is provided to isolate the ground reference. BJS connects the center to the ground, and the ground reference bridge, which spans the 125 V dc power, contains two resistances—one on each side. The VCMI in the R> rack keeps track of PDM variables like the AC and DC sources, P125 and N125 voltages, and the state of fuses 31, 32, and 33.
