Overview
The Sumec Firman SDG63FS is a 70kVA soundproof diesel generator designed to supply independent electric power where connection to the central grid is not available or dependable. It delivers three-phase 220V/380V at 50Hz with protection class IP23 for outdoor-rated operation.
With a 50L fuel tank and a capacity factor of 0.8, this set is built for extended runtime. The package is compact for its output and comes in a soundproof canopy to reduce operating noise on sites and in neighbourhoods.
Voltage and frequency regulation is tuned for steady performance: steady state voltage deviation within ±2.5% and frequency recovery within 3 seconds, helping protect sensitive equipment.
Key features
- Rated Power: 70kVA three-phase output (220V/380V, 50Hz)
- Soundproof canopy for lower onsite noise
- 50L fuel tank for extended operation (specified ≥8h)
- Steady voltage deviation ≤ ±2.5% and frequency range ≤1.5%
- IP23 protection for external installation
What can it power?
Typical load estimate for 56 kW rated output, keeping a 20% safety margin (≈ 46,667 W usable). Motors (fridges, ACs, pumps) need extra power for a few seconds at start-up — that is already counted.
