MP-AUTOMATIC

MP-AUTOMATIC switchboards are used for an automatic load transmission from the mains (when failured) to the genset and contrariwise (after the mains restore). Its major part is automatic control unit, which except that function comprendiously informs about the mains, engine and alternator condition.
MP-AUTOMATIC control boards are fitted with four types of automatic control units:
BE21
BE46
BE2000
InteliGen
 
Besides fuctions, which provide individual control units, the switchboards contains standardly:
- battery charger (charging from the mains),
- emergency stop button,
- terminal board for connection of remote control and signalling
- Control units has a possibility of comunications for local management from PC:
     - Be46 and Be2000 through RS 232, when add a communication modul Be15 and   through RS 485 and GSM modem and mobile phone 
     - InteliGen through  RS232, RS422, RS485, Modbus, CAN bus, modem, GSM modem,internet
Optionally, it is possible to add a remote signalling panel, which standardly contains signalling about engine and generator operation, associated alarm and emergency stop button.
It is possible to complete the switchboard with the other functions as well as to place it outside the genset, which depends of customer’s request. MP-AUTOMATIC switchboards are standardly designed in TNC, or TN-S voltage systems (optionally TT, IT) with protection degree of IP40/20.

MP-MANUAL

MP-MANUAL control boards is used for genset managing working as independent energy source, where the load connection and disconnection is managed by an operator.
Control unit ensures genset protection against emergency conditions and monitors operation parameters of the engine and the generator.
MP-MANUAL control boards are fited with control unit:
 
BE46
Standardly are mounted on the genset frame.
MP-MANUAL control boards are designed in TNC, or TN-S voltage systems (optionally TT, IT) with protection degree IP40/20.

MP- PARALLEL

MP - PARALLEL control boards is used for parallel cooperation of the generating sets or the cogenerating units. Method of this parallel cooperation of the gensets between each other, or with the mains is designed according requests and real user’s necessity. According this requests relate the applied system and equipment of the gensets and MP PARALLEL control boards. It is fitted with automatic control unit:
InteliGen
Standardly are mounted on the genset frame.
MP-PARALLEL control boards are designed in TNC, or TN-S voltage systems (optionally TT, IT) with protection degree IP40/20.

MP-ATS

MP-ATS control boards are segregated from control circuits in separate box with protection degree IP40/20. It is used for automatic switching of the load between the mains and the generator. According the voltage system TNC, or TN-S it contains 3- or 4-poles switches of relevant output and besides this also 3phase 16A mains output for own genset consumption and mains voltage monitoring. Power switches (contactors, motorized disconnecting, or motorized breakers) are ensured against contemporary switching with electric and mechanical interlock. Intake from the mains and from the generator is directly made to the contactors terminals, backed-up output to the appliances is connecting to the terminal box.

MP-MAIN

MP-MAIN control boards are used for disconnecting of the load from the generator and protect the generator against the current overload too. According the voltage system TN-C or TN-S it contains 3- or 4- pole circuit breaker of relevant output and besides this it has also lead out the generator voltage monitoring. This breaker is standardly with mechanical drive, but on customer’s request can be with motor drive too. From about 1000 A it is used the disconnectors, not standard breakers. Intake from the generator is made directly to the breaker terminals. If the genset operates as a stand-by unit, the second side of the breaker is directly connected with the control board MP-ATS and if the genset is operating as an independent power source, the terminals from the breaker are connected to the buses, where will be the load consecutively feeded.
In any cases can be the measuring current transformers placed in the MP-MAIN.
MP-MAIN control boards are segregated from the control circuits in separate box with protection degree of IP40/20.
It is generally placed on the genset frame as close as possible to the generator to be protected in the best way.
