The GCU unit is designed for Observation the Mains supply and control the Generator unit to reduce the Electric power failure condition. It will continue the supply to load either by Mains or by Generator unit (When mains is not available or out of range)
The GCU has the easy operation in any condition Auto/ Manual. In auto mode it monitors the mains condition Normal / Abnormal and then switch ON / OFF the mains on load. In absence of Main supply or abnormality it checks the Generator condition and switch on the generator then monitor the generator supply as Voltage / Frequency and connect the load. Meanwhile if Mains comes the Load will transfer to the Mains immediately & Generator will be running on for 2 minutes on no load to reduce its temperature. It will give alarm on any abnormality or failure condition either in Mains or in Generator.
GCU has following features :
It sense also battery voltage, it will start the Genset whenever battery voltage cross beyond the discharging limit voltage (43V adjustable) at the time of mains failure.
