　　Other names for 3V72H115:

　　Controller Module 3V72H115

　　3V72H115 Analog Module

　　Communication Module 3V72H115

　　Product Positioning and Background

　　Brand and Industry: Wartsila is a leading global provider of marine power, energy systems, and services. 3V72H115 is one of its precision power distribution module series, primarily used in industrial power systems, marine power distribution, and energy management scenarios.

　　Functional Positioning: As a core component of high-voltage/precision power distribution, 3V72H115 undertakes voltage distribution, current monitoring, fault protection, and system integration functions, and is compatible with Wartsila engines, generator sets, and energy conversion systems.

　　Features: Integrated current monitoring, overcurrent/overheat protection, load descent protection, and reverse polarity protection; supports parallel power supply for multiple devices (e.g., radiator fans, fuel pumps, headlights); and features data logging and fault diagnosis.

　　Technical Parameters and Characteristics (estimated based on industry-standard specifications):

　　Electrical Performance:

　　Voltage Range: Supports medium- and high-voltage power distribution (e.g., 3kV-35kV), accuracy ±0.5%, linearity ±0.2%, meeting industrial power grid fluctuation requirements.

　　Protection Functions: Integrated overvoltage/undervoltage, overcurrent, short circuit, and overheat protection; compliant with IEC 61439/62271 standards; supports hardware-level emergency stop chain (E-Stop).

　　Communication Interface: Compatible with industrial protocols such as Modbus, Profibus, and EtherCAT; supports integration with PLCs, DCSs, and Wartsila's proprietary control systems (e.g., Wärtsilä Lipstronic).

　　Input/Output: Supports 10 analog/digital input channels, measurement range 0-6V, 10-bit resolution (0.01V); output is high-side driven, peak current 80A, continuous current 1A, maximum combined output 150A.

　　Protection Mechanism: Each output channel is independently configured with overcurrent, overheat, load descent, and reverse polarity protection, supporting automatic retry after a fault.

　　Communication and Interface: Supports Bluetooth v4.0 (future software update), USB 2.0 (Mini-B), compatible with industrial protocols (such as Modbus, Profibus).

　　Physical Specifications:

　　Dimensions and Protection: Modular design, dimensions approximately 200-400mm (L) × 150-300mm (W) × 50-100mm (H), protection rating IP54-IP65, adaptable to harsh environments (temperature -40°C~70°C, humidity ≤95%).

　　Materials and Installation: Utilizes high-specification FR4 substrate and copper-plated circuitry, supporting DIN rail or backplane mounting, and compatible with rack integration.

　　Application Scenarios and System Integration

　　Core Scenarios:

　　Marine Propulsion Systems: Used for main switchboards, generator parallel control, and propulsion system power distribution, ensuring navigation safety and energy efficiency.

　　Industrial Energy Management: Enables high-voltage power distribution, reactive power compensation, and harmonic mitigation in power plants, chemical plants, and steel mills, supporting dual power supply switching and emergency power supply.

　　New Energy Fields: Adapts to DC power distribution from photovoltaic inverters and wind power converters, and is compatible with energy distribution from energy storage systems (such as batteries and supercapacitors).

　　System Compatibility:

　　Supports seamless integration with Wartsila engines (such as the Wärtsilä 32/46/50 series), generator sets, and automated control systems, providing standardized interfaces and expansion modules (such as encoder interfaces and safety modules).

　　Maintenance and Support

　　Installation and Diagnostics:

　　Requires matching with system voltage level and load characteristics, employs electronic coding, and supports LED status monitoring and real-time monitoring via Wartsila diagnostic software (such as Wärtsilä Diagnostics).

　　Regularly check the cooling fan and clean dust to ensure no overheating risk; spare parts replacement must use Wartsila original certified modules.

　　Maintenance Recommendations:

　　Complies with RoHS directives, supports energy regenerative braking to reduce no-load losses; it is recommended to clean the filter cloth every 500 hours and conduct a comprehensive inspection every 2 years.

　　Summary: The Wärtsilä 3V72H115 precision power distribution module, with its solid-state technology, multiple protections, and intelligent monitoring functions, has become a core component for power distribution in marine, industrial, and new energy fields. Its high reliability, flexible configuration, and data diagnostic capabilities effectively improve system safety and efficiency.
