GE PSP3800HMPK02AC High Voltage Power Supply Module

Product Description: The PSP3800HMPK02AC is a GE Speedtronic Mark VI high voltage auxiliary power supply module for EX2100 excitation system racks. It converts 28VDC rack input power into isolated regulated high-voltage DC power, mainly supplying drive power for excitation pulse firing circuits and gate drive stages of the PCM power converter modules. The suffix 02AC stands for a specific hardware revision with conformal coating, widely used in synchronous generator static excitation cabinets of combined-cycle power plants.

• Dedicated for GE Mark VI EX2100 excitation control rack, compatible with simplex, duplex and TMR redundant architectures
• Input: 28 VDC control power; output isolated high voltage for IGBT gate firing and pulse trigger circuits
• Built-in isolation transformer, EMI filtering, overvoltage, overcurrent and short-circuit protection
• 02AC variant: PCB conformal coating, anti-humidity and anti-salt fog for offshore and corrosive cabinet environments
• 37-pin D-sub connector for backplane interconnection with ESYS and PCM assemblies
• Status LED indicators for power healthy, output fault and trigger channel alarm
• Eurocard plug-in form factor, fits Mark VI VME rack, hot-swappable design
• Convection cooling, designed for continuous operation under high EMC interference in power plant cabinets

Applications:

• Thermal power plant EX2100 generator static excitation cabinet firing power supply
• Combined cycle gas turbine excitation PCM power converter gate drive power source
• Hydroelectric generator excitation system spare maintenance and overhaul
• Offshore platform and oil & gas island power generation excitation retrofit project
• Legacy Mark VI EX2100 system spare replacement

FAQ:

Q: What does PSP stand for in PSP3800HMPK02AC?
A: PSP = Power Supply Pack, the dedicated auxiliary high voltage power pack for EX2100 firing circuits.

Q: Can it work on Mark VIe EX2100eS racks?
A: No, it belongs to classic Mark VI EX2100 architecture and is incompatible with Mark VIe IONet backplane and firmware.

Q: What is the difference between 02AC and other PSP revisions?
A: Different suffix revisions differ in internal transformer rating and component BOM. Must match EX2100 firmware version before replacement, not direct drop-in.

Q: Is PSP3800HMPK02AC still in production?
A: Mark VI EX2100 series is obsolete. Available supply is NOS surplus or fully tested refurbished power supply modules.
