Technical Specifications Applicable System: GE Speedtronic Mark V Input Power Range: Multi‑group DC input from cabinet power unit Output: Multiple channel regulated backplane power supply Operating Temperature: 0℃ ~ +60℃ Storage Temperature: -40℃ ~ +85℃ Mounting: Tray slot installation
Functional Features Distribute stable power for each plug‑in module of Mark V system. Built‑in fuse and over‑current protection circuit. Real‑time monitor power supply working state, feed power failure alarm signal to main controller. Reduce power supply ripple through on‑board filter circuit.
Application Scenarios Power plant gas & steam turbine control cabinet, Mark V system upgrade and maintenance, industrial power generation control equipment spare parts.
Performance Parameters Power output channels: Multi‑channel group output Protection mode: Fuse hardware over‑current cut‑off Power ripple suppression: Low ripple output for logic boards
Structural Characteristics Heavy‑duty industrial multilayer PCB. High‑current power terminals and gold‑plated backplane connector. Power status LED indicators. Metal fixing hardware for cabinet tray installation.
Working Principle External power source inputs to this board, after filtering and over‑current protection processing, each way power is distributed to each functional board through backplane. Monitoring circuit detects voltage abnormality and triggers fault alarm output.
Installation Requirements Install in assigned cabinet tray slot, guarantee connector full contact. Strict ESD operation. Check input power range before power‑on. Reliable ground connection.
Usage Notes Must power off before disassembly. Check fuse status when power supply failure occurs. Cannot replace fuse with non‑specified specification parts.
