Engineered for demanding professional environments, this high-capacity 1500RPM diesel generator combines a robust Baudouin diesel engine, industrial-grade Depco alternator and advanced Deep Sea Electronics control technology to provide dependable power when it matters most.

Delivering 400kVA (320kW) prime power and 440kVA (352kW) standby power, the XL-DB-440 is ideally suited to manufacturing facilities, industrial premises, large warehouses, commercial buildings and critical backup power installations requiring substantial electrical capacity.

Featuring a generous 750-litre integrated diesel fuel tank, Deep Sea Electronics DSE6120 digital control panel and sound-attenuated acoustic enclosure with a specified noise level of 72dB(A) at 7 metres, this professional diesel generator provides an excellent combination of generating capacity, operational convenience and long-term durability.

Powerful 400kVA Three-Phase Diesel Generator

At the heart of the Excel Power XL-DB-440 is a heavy-duty Baudouin 6M21G440/5 six-cylinder diesel engine, operating at a consistent 1500RPM to produce 400V three-phase electricity at 50Hz.

The 12.54-litre turbocharged diesel engine features electronic governing and an efficient water-cooling system, delivering dependable performance for demanding electrical loads.

The XL-DB-440 offers two power ratings to suit different operating requirements:

• Prime Power – 400kVA / 320kW: Designed for applications requiring a primary electricity supply under variable operating loads, subject to the generator's rated operating conditions and applicable emissions requirements.

• Standby Power – 440kVA / 352kW: Provides substantial additional generating capacity for emergency backup applications when the main electricity supply becomes unavailable.

Whether supplying electricity to manufacturing machinery, industrial equipment, commercial premises or essential business infrastructure, the XL-DB-440 provides a robust solution for large-scale three-phase power requirements.

Heavy-Duty Baudouin Diesel Engine

Powered by the renowned Baudouin 6M21G440/5 diesel engine, the Excel Power XL-DB-440 has been engineered for professional power generation applications where strength, durability and dependable performance are essential.

The six-cylinder, 12.54-litre diesel engine features a turbocharged and aftercooled configuration, electronic governing and water cooling to maintain controlled operating temperatures during demanding operation.

Operating at 1500RPM, the engine runs at a lower speed than conventional 3000RPM portable generators, making it particularly suitable for larger industrial generating installations.

The engine delivers a specified 368kW gross prime mechanical power rating, providing the mechanical capacity required to support its substantial electrical output.

Combined with heavy-duty generator construction and a matched industrial alternator, the Baudouin engine provides a dependable foundation for large commercial and industrial power systems.

High-Performance Depco Alternator with Automatic Voltage Regulation

The Excel Power XL-DB-440 is equipped with a Depco DPC354C alternator, designed to deliver consistent three-phase electrical output for demanding industrial and commercial applications.

Featuring Class H insulation, IP23 ingress protection and a shunt excitation system, the alternator provides a robust electrical generating solution for professional installations.

Its integrated Automatic Voltage Regulator (AVR) delivers a specified voltage regulation accuracy of ±1%, helping maintain stable electrical output as operating loads change.

This makes the generator a practical choice for appropriately specified industrial machinery, commercial electrical installations and equipment requiring a dependable three-phase electricity supply.

For installations involving sensitive electronic equipment, large motor-starting loads or specialist machinery, an appropriate electrical assessment should be undertaken to ensure the generator is correctly sized and configured.

Advanced Deep Sea Electronics DSE6120 Digital Control Panel

The XL-DB-440 features the Deep Sea Electronics DSE6120 digital generator controller, providing an intuitive interface for monitoring and managing generator operation.

The control system offers a range of important engine and electrical monitoring functions, helping operators view operating conditions and identify potential faults.

Key monitoring and control functions include:

• Generator voltage and frequency monitoring

• Engine operating status and running hours

• Engine temperature and oil pressure monitoring, where supported by fitted sensors

• Battery voltage monitoring

• Engine protection and fault alarms

• Automatic start and mains failure control functionality

• Compatibility with suitable external switching equipment

For customers requiring automatic backup electricity, the XL-DB-440 can be configured with an optional Automatic Transfer Switch (ATS).

When correctly installed, an ATS arrangement allows the generator to start and transfer connected electrical loads following a mains electricity failure, helping restore power without requiring manual changeover.

Sound-Attenuated Acoustic Canopy – 72dB(A) at 7 Metres

Despite its substantial 400kVA prime power output, the Excel Power XL-DB-440 Silent Diesel Generator features a sound-attenuated acoustic enclosure designed to reduce operating noise.

With a stated noise level of 72dB(A) at 7 metres under free-field conditions, the XL-DB-440 offers a practical solution for commercial and industrial installations where noise management is an important consideration.

The robust acoustic enclosure helps protect the internal generating equipment, while its heavy-duty construction is designed for professional operating environments.

For installations with more demanding acoustic requirements, optional ultra-low-noise canopy configurations may be available.

Final acoustic suitability should always be assessed against the installation location and any applicable planning or noise restrictions.

High-Capacity 750-Litre Diesel Fuel Tank

The Excel Power XL-DB-440 features a generous 750-litre integrated diesel fuel tank, providing substantial on-board fuel storage for industrial power generation and commercial standby applications.

With a stated fuel consumption of approximately 85.5 litres per hour at 100% load, the generator offers convenient fuel storage for demanding operating schedules.

The large fuel tank helps reduce refuelling frequency and provides greater operational flexibility during extended mains electricity failures.

Actual running time will depend on electrical load, usable fuel capacity, reserve requirements and operating conditions.

For customers requiring additional fuel autonomy, optional external fuel tank connections and three-way fuel valves may be specified, allowing integration with suitable external diesel storage arrangements.

Optional Upgrades & Custom Generator Configurations

The Excel Power XL-DB-440 can be configured with additional equipment to accommodate specific electrical, acoustic and operating requirements.

Available options include:

• Automatic Transfer Switch (ATS): Enables automatic generator starting and load changeover following a mains power failure when correctly installed.

• External Fuel Tank Connections: Optional three-way fuel valves for integration with suitable external diesel storage tanks.

• Control Panel Upgrades: Additional control, monitoring and communications options for specialist installations.

• Ultra-Low-Noise Canopy: Enhanced acoustic configurations for installations with stricter noise requirements.

• AREP Alternator Configuration: Optional auxiliary winding arrangement for applications requiring improved performance with certain demanding electrical loads.

• Socket Outlet Options: Alternative electrical output connections, subject to the required configuration.
