SDEC 300 kVA 3-Phase Silent Diesel Generator (GKSD-330) with ATS | Enerlux

Keep operations online through outages and voltage dips with the SDEC 300 kVA 3-Phase Silent Diesel Generator (GKSD-330). Built on a heavy-duty baseframe with an integrated 900 L fuel tank, this set pairs a robust SDEC 6-cyl 11.8 L turbo-intercooled engine with a StromerPower alternator and AVR (SX440) 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 reduces noise and allows secure, easy access for maintenance. Ideal for retail centres, hospitality, medical facilities, offices, workshops, farms and industrial plants needing reliable three-phase backup or prime 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 one tank?
At 75% load, the 900 L tank and typical consumption of ≈56.3 L/h give an indicative runtime of ~16 hours. Actual runtime varies with load and environment.

Q3: Is the output stable for sensitive equipment?
Yes. The AVR (SX440) maintains tight voltage regulation (±1%), suitable for most commercial loads. Additional 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.
