The low load performance of the QAS 60/35 VSG, which features automatic variable speed control from 950 to 2,550 rpm and an integrated energy storage system, enables fuel consumption levels to be reduced by up to 40% against traditional fixed speed generators. At the same time, it helps increase reliability in applications with an average load of less than 20%, such as construction projects, outdoor events or telecoms service duties. The integrated energy storage system helps increase peak power capabilities by 70%, matching the performance of a 60kVA prime power generator. In addition, the QAS 60/35 VSG enables operators to reduce their carbon footprint by offering CO2 emission reductions of up to 40%. 

Fully compliant with European emission standards, the plug and play, environmentally friendly QAS 60/35 VSG is housed in a robust, sound attenuated Zincor steel enclosure that is up to 55% smaller and considerably quieter than the requirements of OND 2000/14/EC sound regulations.  It is said to contribute to operators’ uptime, productivity and revenues through service efficiency and extended engine lifetimes. A maintenance interval of 500h is made possible by the unit’s heavy duty fuel filtration system and water separator. 

Moreover, the new QAS 60/35 VSG allows customers to downsize and optimise their fleets, as one unit can replace up to six power nodes of a typical fixed speed generator from 9kVA to 60kVA.  With a 1 to 1 ratio motor start capability, the QAS 60/35 VSG is a source of high starting current for the electric motor drives of site equipment such as construction tools, cranes, pumps, or electric compressors. The stable frequency and voltage it produces makes it a suitable option when coping with sensitive loads such as electronics equipment applications.
