The S12000 three-phase 400V generator represents the pinnacle of portable generators, combining power, reliability, and above-average battery life. Designed to ensure high performance in both emergency and continuous use, the Pramac S12000 stands out for its build quality and standard features. Equipped with a 20.8 HP , 688 cc , air-cooled Honda GX630 petrol engine , compliant with Stage V emissions standards, it ensures stable power delivery with optimized fuel consumption.
The electric start system, comprehensive control panel, and 24L fuel tank offer convenience and long battery life. The Mecc Alte alternator, combined with capacitor-based voltage regulation, ensures a constant and safe flow of power. Ideal for professional applications, construction, events, or emergency situations, the three-phase S12000 is a safe choice for those seeking a powerful, efficient, and easy-to-use power source.
Electric start
The Pramac AMF automatic control panel is an accessory for S Series generators equipped with a CONN manual control panel . It automatically starts the generator in the event of a blackout and stops it when the mains power returns. Compatible with single-phase and three-phase power supplies, it is installed in a metal wall or floor box . Connection is quick thanks to the plug-in connector, allowing for practical and immediate use. Also included is an RSS radio control with a max. range of 90 m in open field.
An AVR (Automatic Voltage Regulator) is an electronic device that automatically regulates the output voltage of a generator. It maintains stable voltage by compensating for load variations, preventing overvoltages or sags. It is essential for protecting sensitive equipment and ensuring reliable, consistent generator operation.
The DPP (Digital Protection Panel) differential protection is an advanced electronic safety system integrated into Pramac generators that detects any earth leakage currents (typical in the event of accidental contacts or faults in electrical devices).
The Pramac S12000 three-phase generator guarantees high performance thanks to its emergency power (ESP) of 11.1 kW (13.9 kVA) and continuous nominal power (COP) of 9.5 kW (11.8 kVA) . These values make it ideal for both temporary applications and continuous use, maintaining efficiency even under demanding loads.
The heart of the Pramac S12000 three-phase is the Honda GX630 engine , one of the most reliable on the market. With a displacement of 688 cc, 20.8 HP and air cooling , it offers constant performance at 3600 rpm . The electric starting system and mechanical speed regulator allow for simple and safe control, while compatibility with petrol guarantees ease of use and refueling anywhere.
Equipped with a 24 L tank , the generator ensures a runtime of 5.77 hours at 75% load and 4.26 hours at 100% . Consumption stands at 4.16 L/h at 75% and 5.64 L/h at 100% load , allowing for the perfect balance between power and economy. This makes it ideal for construction sites, events or prolonged use without interruptions.
The Pramac S12000 single-phase petrol generator features a robust and functional canopy with large-capacity tanks to ensure above-average autonomy. This Pramac's tank has a capacity of 24 L.
The Mecc Alte brushless alternator with IP23 protection ensures reliability even in demanding working conditions.
