Sincro ET2 Alternators Brushes / Compound, 2 poles/3-phase

Sincro ET2 Series – 2-Pole 3-Phase Alternators with Brushes & Compound Regulation

Synchronous Low Voltage AC Alternators | IP23 | 230/400V | Compact & Powerful

The Sincro ET2 Series offers high-efficiency 3-phase synchronous alternators engineered for demanding industrial and commercial applications. Featuring 2-pole (3000/3600 rpm) operation and brush-type excitation with compound regulation, these alternators are ideal for maintaining consistent voltage under varying loads.

Built with a rugged steel frame and designed for low-voltage power generation (230/400 V – 50 Hz), the ET2 alternators support both three-phase and reinforced single-phase (230 V) output. Their robust design ensures short circuit current > 3.5 In, making them reliable under heavy-duty or unbalanced load conditions.

 Key Features:

• 2-Pole design: 3000 rpm @ 50 Hz / 3600 rpm @ 60 Hz

• Brush-type excitation with compound regulation

• Self-regulated for stable power output

• Standard output: 230/400 V – 50 Hz

• Reinforced phase capability: 400 V 3-phase / 230 V single-phase

• Short circuit current > 3.5 In

• Protection class: IP23

• Mounting options: IM B34, IM B35, SAE 3 / SAE 4 / SAE 5
