ECUSS30 Engine Overspeed Protector / Generator Speed Protection Board (Governor ECU SS30) What it does and why you need it Protects engines and generators by monitoring speed and responding to overspeed conditions. The ECUSS30 is a governorstyle electronic control unit and protection board designed to reduce risk of mechanical damage, electrical faults, and unplanned downtime caused by excessive RPM. Provides stable speed control and fast response to abnormal speed events, helping extend equipment life and improve operational safety. Compact electronic board format makes it suitable for integration into generator control panels and engine management systems that use the SS30 governor ECU form factor. Key benefits Prevents costly engine and alternator damage by detecting overspeed and initiating protective actions. Improves reliability of backup and prime power systems through consistent speed regulation. Reduces maintenance and operational interruptions by providing fast, electronic protection without moving parts. Suitable for retrofit and replacement where an SS30 governor/protection board specification is required. Primary attributes Model: SS30 (ECUSS30) Functionality: Engine overspeed detection, generator speed protection, governor ECU functionality for speed control and protection logic Form factor: Electronic protection/control board (PCB) designed for installation in engine/generator control enclosures Construction: Industrial electronic components selected for reliability in controlsystem environments Performance: Fast response to overspeed events and stable control of engine speed when deployed as a governor ECU Compatibility: Intended for applications and control systems that use the SS30 governor ECU or equivalent speed protection boards; confirm fitment and wiring requirements with system documentation or technical support Typical applications Standby and emergency generator sets — protect critical backup power assets from overspeed during load changes or control faults. Commercial and industrial prime movers — provide electronic speed protection and governor control for diesel or gas enginedriven generators. Rental, construction, and mobile power units — integration into control panels to preserve equipment integrity and minimize service interventions. Installation and usage notes Designed for integration into existing engine or generator control systems that accommodate the SS30 governor/protection board. Verify mounting space, connectors, and wiring compatibility before installation. Installation, configuration, and testing should be performed by a qualified technician familiar with generator control systems and safety procedures. Refer to the system wiring diagrams and OEM guidance for correct connection and configuration. Confirm that the SS30's protective logic matches the operational requirements of your engine and alternator. Reliable protection for critical power equipment The ECUSS30 Engine Overspeed Protector / Generator Speed Protection Board (Governor ECU SS30) delivers focused speed protection and governor control in a compact, serviceable electronic board. Use it where dependable overspeed detection and rapid protective response are required.
