Generator control & protection in one package
The Generator Commander is a new innovation combining generator protection and control into one unit. Compared to traditional systems with several separate units and software, the Generator Commander takes less space and saves considerable hours of engineering time. Operation is smooth as there is only one interface to the system.
- Over 86% space savings compared to traditional solution.
- Less spare parts needed.
- One, easy to use, software saves engineering time
- The included software wizard adapts the data from the generator specifications and calculates the majority of the parameters directly.
- 0,2S class measurement, robust technology and the newest protection functions guarantee the best solution available on the market.
