FUNCTIONAL DESCRIPTION:

IS2020JPDFG02 is a DC Power Distribution Module (125 V) manufactured and designed by General Electric as part of the VIe Series used in GE Distributed Gas Turbine Control Systems. The 125 V dc power distribution module IS2020JPDF accepts redundant 125 V dc power inputs and distributes power to other system boards. JPDF works with a floating dc bus that is centered on Earth rather than with a grounded system. This permits detection of a system ground fault and carries a non-hazardous live 125 V dc rating. Input 125 V dc battery power is connected to a terminal board on the IS2020JPDF module. The power is then routed through a 125 V dc 30 A circuit breaker and line filter before being connected to the IS200JPDF board through the J1 connector. DC voltage is then routed to three fused, non-switched outputs and six fused, switched outputs.

Ac power is routed through the board to the DACA modules where it is converted to dc power. DC power returns to JPDF where it is combined with the battery power input. JPDF can operate with any combination of one or more inputs creating a high-reliability source of 125 V dc power for the control system. The IS2020JPDF module provides full status feedback using a connection to a PPDA I/O pack. Feedback includes bus magnitude, ground fault detection, and detection of excessive ac voltage on the dc bus. Each fused branch circuit is monitored to indicate the presence of output power.

INSTALLATION:

The IS2020JPDF module is base-mounted vertically on a metal back base in a cabinet used by the PDM. A connection must be made between the IS2020JPDF sheet metal and the system protective earth (PE). Input battery power is applied to terminals DCHI and DCLO. If one or two DACA modules are used, ac power is applied to JAF1, typically from an IS2020JPDF module. DACA modules connect to JPDF through connectors JZ2 and JZ3. Output circuits are connected as documented for the system. A power distribution system featuring a PPDA power diagnostic I/O pack requires a 50-pin ribbon cable from the JPDF connector P1 to the P2 connector on the board holding PPDA. This connection can pass through other core PDM boards using the P2 connector.

OPERATION:

Dc battery power is applied to terminals DCHI and DCLO. It then goes through a 30 A dc circuit breaker into a filter assembly located under the IS2020JPDF circuit board. Filtered output is then passed through a series diode to the JPDF circuit board. Ac power is applied to the JAF1 connector. The 115/230 V ac is routed to two connectors, JZ2 and JZ3, and out to two DACA modules. The DACA modules convert the ac power to 125 V dc. The dc power returns to JPDF through the same JZ2 and JZ3 connectors and is combined with battery power if present.

FREQUENTLY ASKED QUESTIONS:

What is a 125 V Power Distribution Board?

A 125 V Power Distribution Board is an electrical component used to distribute and manage power within a system or facility. It is designed to handle a voltage of 125 volts.

What is the purpose of a Power Distribution Board?

The primary purpose of a Power Distribution Board is to receive electrical power from a source and distribute it to various circuits or devices within a system. It helps organize and control the flow of electricity.

How does the module handle power inputs and distribution?

The module accepts two redundant 125 V DC power inputs. The input battery power is connected to a terminal board. It then passes through a 125 V DC 30 A circuit breaker and a line filter before being connected to the board through the J1 connector. The module routes DC voltage to three fused, non-switched outputs, and six fused, switched outputs.
