SDEC 250 kVA 3-Phase Silent Diesel Generator (GKSD-265) with ATS

Keep operations running during outages and unstable grid conditions with the SDEC 250 kVA 3-Phase Silent Diesel Generator (GKSD-265). Built on a heavy-duty baseframe with an integrated 500 L fuel tank, this set pairs a robust SDEC 6-cyl turbo-intercooled engine with a StromerPower alternator and AVR (SX460) for tight voltage control under dynamic loads.
The Smartgen HGM6120N controller delivers full AMF/ATS automation, intuitive LCD metering and comprehensive protection. A weather-resistant, acoustically lined canopy ensures quieter operation and secure access. Ideal for retail centres, hospitality, medical suites, offices, workshops, farms and light-industrial facilities needing reliable three-phase power.

FAQs

Q1: Does it start automatically during an outage?
Yes. The supplied ATS and HGM6120N controller manage automatic start/stop and safe transfer.

Q2: How long will it run on the tank?
At 75% load, the 500 L tank and typical consumption of ≈40.7 L/h give an indicative runtime of ~12 hours. Actual runtime varies with load and environment.

Q3: Is it suitable for sensitive electronics?
Yes. The AVR (SX460) maintains tight voltage regulation (±1%), suitable for most commercial loads. Extra conditioning (UPS/filters) can be added if needed.

Q4: Do you service and support this model?
Yes. Enerlux offers service plans, spares and call-outs. Standard maintenance covers oil, fuel and air-filter replacements per schedule.
