Stephill SSDK20M 15.2kW Super Silent Multi-Voltage Diesel Generator | Kubota Stage V Engine

The Stephill SSDK20M 15.2kW Super Silent Multi-Voltage Diesel Generator is a versatile professional power solution designed for demanding construction, industrial, commercial and emergency standby applications.

It provides a wide selection of 400V three-phase, 230V single-phase and 115V site-power outlets, making it suitable for powering machinery, professional tools, lighting and general electrical equipment from one robust generator.

The SSDK20M delivers a maximum output of 19kVA / 15.2kW at 400V, with a continuous output of 17.3kVA / 13.8kW.

Important Delivery and Offloading Information

Due to the generator’s size and weight, suitable mechanical offloading equipment must be available at the delivery address.

The customer must arrange a:

• Forklift
• Telehandler
• Crane
• Other suitable lifting system

Offloading equipment and labour are not included with delivery. The delivery location must also provide suitable access for the transport vehicle.

Kubota Stage V Diesel Engine

The Stephill SSDK20M is powered by a professional 1500rpm Kubota water-cooled diesel engine.

Its low-speed design is ideally suited to extended generator operation, helping to provide reliable performance, reduced engine wear and lower operating noise.

The engine complies with EU Stage V emissions requirements and incorporates protection systems for:

• High engine temperature
• Low oil pressure

These protective features automatically shut the engine down when potentially damaging operating conditions are detected.

Multi-Voltage Power Output

The SSDK20M provides a comprehensive range of outputs for different professional applications.

At 400V, it delivers:

• Maximum power: 15.2kW
• Continuous power: 13.8kW

At 230V/115V, it delivers:

• Maximum power: 14.0kW
• Continuous power: 12.8kW

The fitted socket configuration includes:

• 1 × 115V 16A
• 3 × 115V 32A
• 1 × 230V 16A
• 2 × 230V 32A
• 1 × 400V 32A
• 1 × spurred 230V 16A outlet

This makes the generator particularly suitable for construction sites requiring 115V power while also supporting standard 230V equipment and compatible 400V three-phase machinery.

Deep Sea DSE3110 Controller

The integrated Deep Sea DSE3110 controller provides simple push-button starting and stopping.

It also incorporates a two-wire remote-start facility, allowing the generator to be activated by compatible external controls or a suitably configured automatic transfer system.

The lockable control-panel housing protects the controls and helps prevent unauthorised operation.

Super-Silent Acoustic Enclosure

The SSDK20M is housed within a close-fitting acoustic cabinet engineered to reduce operating noise and protect the internal components.

The enclosure is manufactured from Zintec steel, helping provide increased resistance to corrosion and demanding outdoor working conditions.

Large access doors provide convenient entry for routine servicing, inspection and maintenance.

The generator produces a stated noise level of approximately 64dB(A) at 7m, making it suitable for applications where reduced sound levels are important.

Brushless AVR Alternator

The generator is equipped with a maintenance-free brushless alternator incorporating Automatic Voltage Regulation.

The AVR system regulates the output voltage to approximately ±1%, helping provide a stable electrical supply for connected machinery, tools and equipment.

Long-Running Fuel Tank

The integrated 120-litre diesel tank provides up to approximately 26 hours of operation, depending on the connected load and operating conditions.

This extended runtime makes the SSDK20M suitable for prolonged site use, remote applications and standby installations where frequent refuelling would be inconvenient.

The Stephill SSDK20M is suitable for:

• Construction and infrastructure projects
• Industrial premises
• Workshops and manufacturing facilities
• Agricultural operations
• Equipment-hire fleets
• Commercial backup power
• Temporary site power
