Core Function

JPDD DC power distribution module for Mark VI and EX2100 excitation system. It receives 28VDC P‑bus power input and distributes stable DC power to EROC, ERIO, ERDD, DSPX and other board cards inside excitation rack. Each output channel is equipped with independent protection circuit to avoid single‑board short‑circuit causing whole‑rack power failure. It supports simplex and TMR triple‑modular redundant excitation cabinet configuration, provides reliable power supply guarantee for all control boards in excitation system.

Product Details

The IS200JPDDG1AAA is JPDD series DC power distribution module for GE Speedtronic Mark VI and EX2100 excitation control system.

This 6U VME rack‑mount power distribution board serves as power hub inside EX2100 excitation cabinet. It receives 28VDC P‑bus power source, then distributes multi‑group DC power to each functional control board in the rack. Every output channel adopts independent over‑current and short‑circuit protection design, effectively isolating fault points, preventing fault spread to the whole system. On‑board LED indicators can quickly reflect power input status and abnormal conditions of each power channel, convenient for on‑site inspection and fault troubleshooting. Conformal coated circuit board improves anti‑vibration, moisture‑proof and anti‑electromagnetic‑interference performance, adapts to high‑noise harsh working environment of power‑plant excitation cabinet. Widely deployed in simplex and TMR triple‑modular redundant generator excitation cabinets for gas‑steam turbine units.

It belongs to critical power supply spare‑part for EX2100 excitation system, widely used in overhaul and renovation projects of power generation units.

It is important spare hardware for excitation cabinet power loop debugging and defective IS200JPDDG1AAA board replacement.
