Full Specification

The Cummins C38D5Q is a silent diesel generator offering 38 kVA standby / 35 kVA prime output, engineered for stationary standby and prime applications across commercial and industrial sectors.

Driven by a Cummins X3.3‑G1 naturally aspirated 4-cylinder engine at 1500 rpm, it delivers stable performance with ± 2.5% voltage regulation and droop frequency control. The Stamford S1L2‑J1 alternator ensures reliable 400 V three-phase power. The PowerStart 0600 microprocessor-based control system enables automatic start/stop, comprehensive diagnostics, metering and AMF functions.

Standard features include a 55 L base fuel tank (≈ 8.6 h autonomy at 75% PRP), coolant heater, flooded SLI battery with charger, and a quiet canopy delivering ~76 dB(A) at 1 m and ~64 dB(A) at 7 m. The genset is CE/UKCA certified and backed by a full warranty network.
