Key Features
-
Stable Control-Level Power Delivery
- Converts wide-range 18–36 VDC input to regulated 12 VDC output for turbine drives, cabinet fans, and auxiliary controls.
- High efficiency (≥92%) minimizes energy loss and heat generation, enhancing system reliability.
-
Flexible Configuration & Calibration
- Equipped with 7 DIP switches and 12 jumpers for precise input scaling, voltage adjustment, and mode configuration.
- DIP switch SW4 adjusts voltage scaling for the VCO (Voltage-Controlled Oscillator) output bridge circuit, enabling customization for diverse turbine applications.
-
Comprehensive Protection & Diagnostics
- Integrated over-current, over-voltage, and short-circuit protection safeguards the board and connected loads from electrical damage.
- Three protective fuses isolate faulty circuits; LED/neon indicators provide immediate visual alerts for fuse failures (±24 VDC and 115 VAC lines).
- Five test points facilitate on-site troubleshooting and voltage/current verification without disassembly.
-
Robust Industrial-Grade Design
- Ruggedized PCB with conformal coating (standard coating) resists dust, moisture, and chemical corrosion in harsh industrial environments.
- Wide operating temperature range (-40°C to +85°C) ensures reliable performance in extreme power plant and process conditions.
- Backward-compatible with early Mark V revisions (1st two revisions) for seamless system upgrades and replacements.
-
Seamless System Integration
- Designed for direct integration with GE Mark V Speedtronic turbine control systems, including EX2000, DC2000, FC2000, GF2000, ME2000, CB2000, and AC2000 IGBT drive applications.
- Communicates with SDCC/LDCC control boards via dedicated connectors, enabling real-time voltage feedback adjustment and signal transmission.
