Hello Forum, I am building a 250A précharge due to the fact I am corona bored.
The is nothing else to do.
Here my project. It is a test board, sorry but not perfect. Using hot glue to makes things stick.
To power my précharge circuit I am using a battery pack. Here my parts.
For the delay circuit I am using an AE delay . This is connected to my 250A inert gas filled relay. Automotive Type.
The trigger switch is activate the small 12V Relay which has a cement resistor and a light bulb in series. When I pull the trigger switch the current is running though the resistor the light is on and bypasses the big contacter/Relay. I am precharging my load with 100mA.
It that is enough ? is driven by the delay time which can be adjusted from 2s to 30s and more.
The current consumption of the contacter is 300mA when it is acting connected.
Is will connect the contacter with the remote switch on my 2000,00000Watts inverter.
What do you think, is a precharging current of 100mA is sufficient. I have no idea about the cap sizes of my inverter.
5Tau = R x C.
Will see maybe on the scope.
Regards Bob
