Excel Power XL-DK-138 | 125kVA Silent Diesel Generator | 400V Three Phase | 1500RPM

The Excel Power XL-DK-138 125kVA Silent Diesel Generator is a powerful, heavy-duty three-phase generating set designed to deliver reliable electricity for commercial, industrial and standby power applications. Engineered for demanding environments, this professional 1500RPM diesel generator combines a robust Depco diesel engine, high-performance alternator and advanced digital control technology to provide dependable power when it matters most.

Delivering 125kVA (100kW) prime power and 138kVA (110kW) standby power, the XL-DK-138 is an excellent choice for commercial premises, manufacturing facilities, agricultural operations, industrial installations and permanent backup power systems.

Featuring a 159-litre integrated fuel tank, Datakom D100 digital control panel and sound-attenuated acoustic enclosure with a stated noise level of just 70dB(A) at 7 metres, this industrial diesel generator offers an excellent combination of high-capacity power, operational convenience and long-term durability.

Powerful 125kVA Three-Phase Diesel Generator

At the heart of the Excel Power XL-DK-138 is a heavy-duty Depco 48ETD125 four-cylinder diesel engine, operating at a consistent 1500RPM to produce stable 400V three-phase electricity at 50Hz.

The 4.84-litre turbocharged and intercooled diesel engine features electronic governing and an efficient water-cooling system, delivering dependable performance for demanding electrical loads.

The XL-DK-138 offers two power ratings for different operating requirements:

• Prime Power – 125kVA / 100kW: Designed for applications requiring a primary electricity supply under variable operating loads, subject to the generator's permitted operating conditions and emissions requirements.

• Standby Power – 138kVA / 110kW: Provides additional capacity for emergency backup applications when the main electricity supply becomes unavailable.

Whether supplying power to industrial machinery, commercial buildings, agricultural equipment or critical business infrastructure, the XL-DK-138 provides a robust solution for substantial three-phase electricity requirements.

Heavy-Duty Depco Diesel Engine

Powered by the Depco 48ETD125 diesel engine, the Excel Power XL-DK-138 has been engineered for professional generating applications where durability, consistent performance and reliability are essential.

The four-cylinder, 4.84-litre engine features a turbocharged and intercooled configuration, electronic governing and water cooling to maintain stable operating conditions.

Operating at 1500RPM, the engine runs at a lower speed than conventional 3000RPM portable diesel generators, making it well suited to larger industrial generating applications.

The engine and alternator are mounted on heavy-duty anti-vibration supports, helping reduce vibration transfer to the surrounding structure and minimise mechanical stress during operation.

With a specified 127kW gross prime engine power rating, the XL-DK-138 delivers the engine capacity required for its substantial electrical output.

High-Performance Alternator with Automatic Voltage Regulation

The Excel Power XL-DK-138 is equipped with a Depco DEPCO-96-3 alternator, designed to produce consistent three-phase electrical output for professional commercial and industrial applications.

Featuring Class H insulation, IP23 ingress protection and a self-excitation system, the alternator offers a robust electrical generating solution.

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

This makes the generator suitable for appropriately specified commercial electrical systems, industrial machinery and equipment requiring a dependable three-phase power supply.

Advanced Datakom D100 Digital Control Panel

The XL-DK-138 features the Datakom D100 digital generator control panel, providing a straightforward interface for monitoring and managing generator operation.

The control system supports essential operating information, engine monitoring and protective functions, helping operators identify potential faults and maintain reliable performance.

The generator is also described as having a coolant heater and battery charger, supporting cold-weather starting readiness and battery maintenance during standby periods. The inclusion of these items should be confirmed against the final supplied specification.

For customers requiring automatic backup electricity, the XL-DK-138 can be configured with an optional Automatic Transfer Switch (ATS), allowing the generator to start and transfer connected electrical loads following a mains power failure.

Sound-Attenuated Canopy – 70dB(A) at 7 Metres

Despite its substantial 125kVA prime power output, the Excel Power XL-DK-138 Silent Diesel Generator features a sound-attenuated acoustic enclosure designed to reduce operating noise.

With a specified noise rating of 70dB(A) at 7 metres under free-field conditions, the XL-DK-138 is a practical choice for commercial and industrial installations where noise management is an important consideration.

The heavy-duty enclosure provides protection for the generating equipment, while its robust construction is designed to withstand the demands of professional installations.

For sites with more restrictive noise requirements, optional ultra-low-noise canopy configurations may be available.

Integrated 159-Litre Diesel Fuel Tank

The Excel Power XL-DK-138 features an integrated 159-litre diesel fuel tank, providing convenient on-board fuel storage for commercial standby and prime power applications.

The generator is also described as incorporating bunded fuel containment, helping reduce the risk of diesel escaping into the surrounding environment in the event of a fuel leak. The tank's bunding capacity and specification should be confirmed before installation.

Its integrated fuel storage provides a practical solution for commercial premises, agricultural installations and industrial facilities where convenient on-site fuel management is essential.

For applications requiring longer running periods, optional external fuel tank connections and three-way fuel valves may be specified, allowing integration with suitable external diesel storage systems.

Optional Upgrades & Custom Generator Configurations

The Excel Power XL-DK-138 can be configured with a range of additional equipment to meet specific installation requirements.

Available options include:

• Automatic Transfer Switch (ATS): Enables automatic generator starting and load transfer during mains electricity failures when correctly installed.

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

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

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

• AREP Alternator Configuration: Optional auxiliary winding arrangement for applications requiring improved motor-starting and short-circuit performance.

• Socket Outlet Options: Alternative electrical output configurations, subject to requirements.
