Manual cotrol cabinet KO-R MRS

Manual control cabinet can be mounted on genset or delivered separately. It includes the entire control and management of the engine and generator, and remote start of the genset. By pressing a button (key) genset starts and stops (also from a remote location). Genset can also start and stop by signals to be obtained from the outside (remote start).

It consists of a metal electrical cabinet, manual control panel of the genset SMC10, the generator protection circuit breaker, emergency stop key and fuses. The cabinet is ready to connect the power cable for consumers on a copper strip or staples.

Automatic control cabinet KO-A AMF

Automatic control cabinet can be mounted on genset or delivered separately. It includes the entire control and management of the engine and generator, and remote start of the genset. It allows the automatic start of the genset at main power network failure and stop on its return. Automatic control cabinet can operate in the following modes: AUTO / MANUAL / TEST / OFF. Genset management is provided by the keys with mechanical feedback and a large graphic display. Management and control can be run also through remote computer (PC). It is possible to connect generating sets in the network.

It consists of a metal electrical cabinet, automatic control panell of the genset SAC35, the generator safety switch, emergency stop key and fuses. The cabinet is ready to connect the cable of the consumers on a copper strip or staples.

Paralel synchonization control cabinet KO-P AMF

Automatic sync control cabinet can be mounted on genset or separately. It includes the entire control and management of the engine and generator, and remote start of the genset. It enables the automatic start of the genset when main power network fails and stops on its return. It also enables synchronization of network and genset and parallel operation of the genset and main electric network. The parallel synchronization control cabinet can also cover electrical spikes. In  case that the designated facility needs additional electricity, genset in parallel operation can add this deficit to the main electrical grid. Genset can also cover a specific part of the power so that is no need  to be collected from the main electricity network and pay credits at a higher rate.  Genset performs uninterrupted switching between the network and genset. It is also possible for uninterrupted test of the genset at full or partial load. Genset management is possible by keys with mechanical feedback and a large graphical display. Management and control can be run also through remote computer (PC). It is possible to connect generating sets in the network.
