Behind these specifications is a generator built to meet the toughest emissions standards on the market today. The Tier 4 Final rating means this unit can be deployed in California and other CARB-regulated jurisdictions where older emissions tiers are no longer permitted, without sacrificing the power output facilities depend on.

Power Output Built for Demanding Three-Phase Applications

This generator delivers a strong 500 kW standby rating and 450 kW prime rating, giving facilities flexibility depending on whether the unit serves emergency backup or continuous operation. The three-phase configuration supports 480/277V and 208/120V options, while a single-phase 240/120V configuration is also available for facilities with different electrical infrastructure. 

This range of voltage options makes the unit adaptable to commercial buildings, data centers, and industrial sites with varying power requirements.

Engineering Details of the Perkins Engine and Leroy Somer Alternator

The Perkins 2806F-E18TAG1 engine is turbocharged, aftercooled, and liquid-cooled, with electronic governing that keeps frequency regulation tight and consistent under changing loads. 

The Leroy Somer TAL-047-D alternator pairs enhanced auxiliary excitation (AREP) with advanced digital voltage regulation, delivering stable output even during motor starts and load transients thanks to its soft-start capability. This combination of engine and alternator technology is designed to give facilities dependable, clean power without the harmonic distortion issues that can affect sensitive electronic equipment.

Built for Reliable Operation in Demanding Environments

Construction quality reflects the standards this unit is designed to meet. The DeepSea DSE7320 MKII controller offers full digital auto start/stop functionality along with comprehensive monitoring of engine and electrical parameters, giving operators clear visibility into generator performance at all times. 

The brushless alternator design reduces maintenance requirements over the unit's service life, while the electronic governor helps protect the engine and connected equipment from frequency fluctuations during load changes.

Emissions Compliance and Facility Fit

This generator's Tier 4 Final certification makes it one of the cleanest diesel options available at this power rating, an important consideration for facilities in California, the Northeast, and other regions with strict emissions requirements. 

Businesses that need standby or prime power without running into regulatory roadblocks will find this unit well suited to hospitals, data centers, industrial plants, and commercial facilities where both performance and compliance are non-negotiable.
