AQT 15 kVA Diesel Generator Set with PERKINS 403A-15G1 Engine & AL-040-C Alternator

The AQT 15 kVA diesel generator set is engineered for reliable prime and standby power applications. Featuring the dependable PERKINS 403A-15G1 3-cylinder diesel engine, this genset delivers 15 kVA (11.4 kW) of prime power and 17.5 kVA (13.9 kW) of standby power. It operates at 400V, 50 Hz, with a power factor of 0.8. The generator maintains excellent voltage regulation within ±1%, with a total harmonic factor under 3.5% and a telephone influence factor below 50.

This model is paired with a Leroy Somer or Stamford AL-040-C alternator—self-excited, 4-pole, brushless synchronous—with insulation class H and ingress protection rating of IP23. It includes an R120 AVR for automatic voltage control. Cooling air flow is maintained at 0.06 m³/sec. The system complies with major global standards including ISO 3046, BS 5514, IEC 60034, and NEMA MG1.
