Littelfuse T4800.0060 - Load Sharer. 120/127V 5A. The T4800 is designed to control a generator operating in parallel with the grid, or a generator operating in parallel with other generators (which are also controlled by T4800 units). The T4800 will continuously measure and compare the active current on the generator to an external DC reference signal connected to the “parallel lines” input. The T4800 will increase or decrease the speed of the generator (through the governor) if it finds the active current level to be either too low or two high. Two built-in relays provide the increase and decrease pulses for a conventional governor. The strength (width) of the pulses is proportional to the frequency/phase deviation. The E7800 Motorised Potentiometer can be used to adapt the contact pulses to a signal suitable for the speed trim input of an electronic speed controller.

Littelfuse C6200.0060 - FlexGen Generator Controller - Basic. Integrated generator controller. The C6200 provides load depending start and stop, automatic synchronization and active / reactive load sharing for one diesel generator (3 phase). The C6200 will also ensure that the generator is always operating at the nominal speed / frequency no matter the load. Advanced grid paralling and Power Factor function are provided as standard. Programmable inputs and outputs allows for easy integration with PLC control. The C6200 can be operated in either fully automatic mode, semi-automatic mode or in manual mode.

Littelfuse M0600.0010 - Shutdown Unit 24VDC Delay for SPA. The unit has inputs for over speed, low oil pressure and a user defined input which can be used to monitor e.g. high water temperature. The M0600 has an input to indicate that the engine is running and another input to indicate that the engine is in the process of being halted. An output relay will give a closing signal, which can be used to stop the engine via the fuel valve or the stop solonoid (if available). The M0600 will work as a stand-alone protection unit for DIN-rail mounting. Alternatively, when limited space is available, the M0600 can be mounted directly on the rear side of the M2000 Engine Controller.
