Sincro EK/R series Alternators Constant Speed, Brushless/AVR, 2-poles/1-phase

Sincro EK/R Series – Single-Phase Alternators with Brushes and AVR

2 Poles | 3000–3600 RPM | IP23 | Low Voltage AC | ±2% AVR Regulation

The Sincro EK/R Series is a powerful line of single-phase synchronous alternators designed with brush excitation and integrated AVR (Automatic Voltage Regulation). Engineered for stable power delivery and excellent voltage accuracy, the EK/R series is ideal for both continuous-duty and backup applications, particularly where voltage-sensitive equipment is in use.

Key Features
