Key Features
Advanced Excitation

Permanent magnetic generators provide invariable excitation under all operating conditions with brushless design for reduced maintenance.

Superior Winding Design

2/3 pitch windings effectively eliminate third harmonic waves (3rd, 9th, 15th), making it ideal for UPS applications and nonlinear loads.

Robust Construction

Balanced rotor with sealed ball bearings, H-class insulation, and IP21/IP23 protection for harsh environments.

Easy Integration

Standard 12/6 wire terminals facilitate easy connection to power networks or parallel operation with other generators.

Mechanical Features
  • Frame Protection: IP21 standard, IP23 optional
  • Rotor Balance: All rotors pass balance test per BS6861 standards
  • Terminal Box: 12 leads brought out to terminals on non-drive end with removable panels
  • Voltage Regulation: ±3% fluctuation with power factor 0.8-1, adjustable via AVR potentiometer
Electrical Performance
  • Insulation: Class H with special materials and immersion lacquer processing
  • Winding Protection: Continuous damp windings reduce surges and voltage distortion
  • Interference Control: THF <2%, TIF <50 with minimal radio interference
  • RFI Filter: Optional RFI noise filter available for sensitive applications
Available Options
  • Adapters and drive disks
  • Remote voltage adjustment
  • IP23 enclosure
  • Space heaters
  • Thermistors
