The WOSP 300 series is based on the latest Denso platform of super efficient alternators. Due to their patented design, these compact units offer an unrivalled power/weight ratio compared with the competition, and they also start producing power at much lower speeds. In fact, their design enables them to give 80% of their max output at idling speeds.
The bodies and mountings are CNC machined in house at WOSP, enabling many different models to be offered, varying in output from 95 to 390A. The performance curves of the various base platforms of the 300 series can be seen in the PDF link below.
