GE 5K182BK361B
Product Description
The 5K182BK361B is a dedicated power conversion module for GE’s Mark VIe gas turbine control system, and a key power management component of the Speedtronic™ series. Designed to convert AC input power (120/240V AC) into isolated 24V DC output, this module provides stable power for I/O modules (such as the IS200/DS200 series) within Mark VIe control cabinets. It also features redundant switching and fault diagnosis functions.
The 5K182BK361B adopts high-efficiency switching power supply technology (efficiency > 90%), supports a wide input voltage range (85-264V AC), and operates in harsh environments (-40°C ~ +70°C). It is suitable for scenarios with extremely high requirements for power supply reliability, such as power plants and offshore platforms. Its modular design allows for quick replacement, and remote monitoring is enabled via LED status indicators and RS-485 communication interfaces.

Structure and Composition
The 5K182BK361B consists of the following core components:
Power Conversion Layer
- Active PFC circuit (power factor > 0.95), compliant with IEC 61000-3-2 harmonic standards.
- High-frequency transformers use triple-insulated wires to ensure 3000V isolation withstand voltage.
Control and Protection Layer
- Digital PID controller (±1% voltage accuracy).
- Integrated TVS diodes and MOVs, passing IEC 61000-4-5 4kV surge tests.
Monitoring and Communication Layer
- Uploads voltage/current/temperature data via RS-485 (supports Modbus RTU).
- Front-panel LEDs display input normal (green) and fault (red) statuses.
Key Features and Advantages
High Reliability Design
- Industrial-grade components (105°C electrolytic capacitors) with a lifespan of 100,000 hours @ 40°C.
- Supports parallel redundancy (paired with 5K182BK362B) with switching time < 10ms.
Intelligent Monitoring
- Real-time monitoring of output current/voltage, with threshold alarms configurable via ToolboxST software.
- Temperature compensation to avoid high-temperature derating.
Strong Environmental Adaptability
- Cold start capability at -40°C, passing IEEE 1613 anti-vibration certification (5G vibration).
- Compliant with UL 60950-1 and EN 50155 (rail transit standards).
Plug-and-Play Maintenance
- Supports hot-swap replacement (requires redundant configuration).
- Modular design for tool-free disassembly.
Installation and Maintenance
Pre-Installation Preparation
- Confirm input voltage matches jumper settings (120V/240V optional).
- Install 120Ω terminal resistors for RS-485 communication lines.
- Check grounding resistance < 1Ω (6AWG copper cable recommended).
Maintenance Recommendations
- Clean heatsink dust every 6 months (using compressed air ).
- Calibrate voltage detection accuracy annually (using Fluke 289 multimeter).
- Record Modbus address during replacement (default ID=1).
