Sincro SKA Heavy- Duty Alternators IP55 4 pole air to air cooled for oil & gas

Sincro SKA Series Alternators: Heavy-Duty IP55 Synchronous AC

SYNCHRONOUS LOW VOLTAGE AC AIR/AIR COOLER – 4 POLES 3 PHASE BRUSHLESS/AVR

The Sincro SKA series represents top-tier synchronous low voltage AC alternators. Manufactured by Soga Energy Team, these 4-pole, 3-phase brushless alternators are engineered for constant speed and demanding industrial applications. Featuring a robust totally enclosed fan-cooled (TEFC) IP55 design with air-to-air cooling, they guarantee reliable power generation even in harsh environmental conditions.

Key Features & Advantages

• Advanced Protection: The IP55 protection degree ensures excellent defense against dust and water ingress.

• High-Quality Excitation System: Features a brushless design equipped with an Automatic Voltage Regulator (AVR).

• Power Supply Configuration: The SKA 355 is powered from an auxiliary winding (PMG available on request), while the SKA 450 and SKA 500 models come standard with PMG.

• Enhanced Durability: Built with bearings that are specifically dimensioned for heavy-duty applications.

• Superior Performance: Offers a short circuit current of > 300% In for 10 seconds and maintains total harmonic distortion below 2%.

• Exceptional Stability: Voltage regulation accuracy is ≤ ±0.5%, and the transient voltage drop for a rated step load at 0.8 power factor is less than 18%.

• Digital Control: Equipped with a digital AVR (Digital Basler AVR is also available on request).

• Optimized Electrical Build: Includes tropicalization and a 2/3 winding pitch for optimal electrical performance.

• Coupling Versatility: Available with standard SAE or IM B34 couplings.

• International Standards: Fully compliant with EN 60034-1, IEC 60034-1, and ISO8528-3, alongside BV and CSA/UL certifications.

• Customization: Special configurations are available upon request to fit unique project requirements.

Technical Specifications

Power Ratings (50 Hz / 1500 rpm / Class H 40/125 °C)

The following table highlights the rated power outputs for the SKA series at standard 400V operating at 50 Hz:

Standard Operating Conditions

To achieve the manufacturer's rated power outputs, these alternators should be operated under the following standard environmental conditions:

• Ambient temperature must not exceed 40 °C.

• Altitude must be below 1000 meters above sea level.

• The system requires a power factor of 0.8 and a symmetrical non-distorting load.

Note: Operational correction factors apply for ambient temperatures up to 55 °C and altitudes up to 3000m.
