Description:
The generators with electronic voltage controller are available as one- or three-phased AC power supply units for frequencies between 100 and 2000 Hz.
In ships the installation is suitable for operation by the ship's main engine where there is variable speed but can also be used in connection with an auxiliary machine for constant speed.
The installation consists of a generator which supplies a three-phased AC voltage and a rectifier/controller which rectifies the AC voltage to DC voltage and at the same time controls the DC output voltage.
During start-up the installation will self-generate voltage thus rendering the use of any outside supply point unnecessary.
Constant output voltage is maintained over speed variations at the ratio of one to four as well as load and surrounding temperature variations. Furthermore, the installation is current-limited, with or without time delay, depending on the use. This involves overload protection.
In addition, the installation is over voltage- and excess-temperature protected.
Installations with the same voltage requirements can operate in parallel in all conditions.
The installations, available with outputs from approx. 1 - 45 kW, meet the international classification standards
