12. Technical specifications
We reserve the right to make technical changes to reflect further development.
a) Performance

= describes the relationship of effective power to apparent power
b) Protection class = Extent of protection offered by housing against penetration of solid foreign matter and
water (IP23 = protection against solid foreign matter > 12.5 mm

and against splash
water)
c) Insulation class = Class of the insulation materials used and their highest permitted constant
temperature (B = highest permitted constant temperature 130°)
Electric generator use
The BOOSTER.PRO is designed in such a way that it is possible to use a power
generator at any time. However, you should bear in mind that the Technical
specifications specified in this Chapter must be adhered to.
We recommend an asynchronous or synchronous generator with 20kVA constant
power.
Please note that the BOOSTER.PRO monitors the grid voltage continuously and the
use of not suited electric generators may trip a failure.
