GE IS400JPDHH1ACE Power Distribution Board in stock

GE IS400JPDHH1ACE is a high-density JPDH power distribution board for GE Speedtronic Mark VIe turbine control system. It distributes regulated 28VDC power supply to multiple I/O packs, communication boards and network switches inside the control rack, serving as the central power distribution hub for the whole cabinet.

This board integrates independent PTC overcurrent protection for each output channel, with built-in voltage monitoring and fault reporting function. It supports daisy-chain expansion to supply more I/O modules, widely used in gas turbine, steam turbine and generator excitation control cabinets, and is a common spare part for power plant Mark VIe system maintenance.
