SDMO V450U IV Diesel Generator: Enclosed and Export Only Power Solution

The SDMO V450U IV is a heavy-duty three-phase diesel generator built for large-scale backup and prime power needs, pairing a powerful Volvo engine with a Leroy Somer alternator inside a fully enclosed, weatherproof housing. Designed strictly for export, every unit arrives brand new and backed by a two-year warranty.

• Engine: Volvo TAD1640GE, turbocharged, four-stroke, 1800 RPM, liquid cooled with electronic governor
• Alternator: Leroy Somer LSA472S5, 12-lead brushless, IP23 protection, insulation class H
• Standby rating: 450 kW / 563 kVA at 60Hz, three phase, 0.8 power factor
• Prime rating: 409 kW / 511 kVA continuous duty
• Control panel: SDMO TELYS2 digital auto-start/stop with remote monitoring capability
• Main breaker: Schneider, three pole, CSA and UL listed
• Fuel system: Integrated day tank with 500L capacity for extended daily autonomy
• Enclosure: IP56 rated, 12 gauge electro-zinc coated steel, 29dB(A) internal silencer
• Dimensions: 5031mm x 1560mm x 2435mm, net weight 4740kg
• Version: Enclosed (Fully Weather Proof Silent Enclosure)
• EPA Compliant: Export Only

Engineered to accept 100% rated load in a single step per NFPA110 standards, the V450U IV also meets ISO8528-5 class G-3 for transient response. Its scale and output make it well suited for facilities where large, uninterrupted power capacity is a requirement rather than an option.

What Makes the SDMO V450U IV Different

Beyond raw output, the V450U IV distinguishes itself through the quality of its enclosure construction. The 12 gauge electro-zinc coated steel passes through phosphatizing degreasing, non-chromic passivation, and osmosis purified rinsing before receiving a high durability polyester resin powder coat. The result is an automotive grade finish that holds up against fading, scratching, and corrosion across years of outdoor exposure.

Acoustic performance is handled with equal care. Up to 51mm of insulation combined with a hydrocarbon sealing film meets UL 94 HF1 and FMVSS 302 flammability standards while resisting moisture absorption. The internally mounted 29dB(A) critical silencer keeps operating noise low, and a vertical discharge grille directs hot air upward, reducing ambient noise around the unit while maintaining strong airflow.

SDMO Engineering Built for Heavy Industrial Use

Every SDMO V450U IV unit is prototyped and individually factory load bank tested prior to shipping, all within ISO9001:2008 quality controlled facilities. This level of scrutiny supports compliance with a wide range of international standards, including ISO3046, ISO8528, BS4999, BS5514, AS1359, IEC34, and VDE0530, giving buyers confidence the unit will perform consistently under real-world load conditions.

Enclosed, Weatherproof, and Easy to Service

Serviceability was clearly a design priority. Multi-personnel doors give technicians direct access to the fuel fill, fuel gauge, oil fill, and battery, while the interchangeable modular panel construction allows individual sections to be repaired or swapped without disturbing the rest of the enclosure. Remarkably, the entire enclosure can be removed or reinstalled in under 30 minutes with no disassembly required, minimizing downtime during major service work.

Voltage Flexibility for Export Applications

Since this unit is offered for export only, voltage flexibility matters. The V450U IV supports configurations including 208/120V, 220/110V, 230/115V, 240/120V, 416/240V, and 480/277V, covering the electrical standards of a wide range of countries. Optional upgrades such as aluminum enclosures, UL142 listed fuel tanks, UL1008 automatic transfer switches, and remote annunciators are also available.

Complete with a full user guide, wiring diagrams, and a two-year warranty, the SDMO V450U IV is built to deliver dependable power wherever heavy industrial or commercial demand calls for it.
