System Construction Configurations

The external appearance of EURO-DIESEL’s No-Break KS® resembles Single Stand-Alone Unit
that of a conventional generating set. For simple low component count reliability.
However, it consists of a diesel engine coupled by means of an
electromagnetic clutch to a stato-alternator, which is the combination of Dual Output
a synchronous machine and a kinetic energy accumulator. A dual output design can be configured to provide site critical and
The No-Break KS® system also involves a choke and 3 circuit breakers. non-critical loads, removing the requirement for gensets. There are
variations of this design to suit isolated or non-isolated schemes.
