Permanent magnetic generators provide invariable excitation under all operating conditions with brushless design for reduced maintenance.
2/3 pitch windings effectively eliminate third harmonic waves (3rd, 9th, 15th), making it ideal for UPS applications and nonlinear loads.
Balanced rotor with sealed ball bearings, H-class insulation, and IP21/IP23 protection for harsh environments.
Standard 12/6 wire terminals facilitate easy connection to power networks or parallel operation with other generators.
- Frame Protection: IP21 standard, IP23 optional
- Rotor Balance: All rotors pass balance test per BS6861 standards
