Hi all,
I am busy building a CT for overload protection on an inverter(500W, 12V-240V). I am using the CT to trigger an op amp which is intended to trigger a relay to open the circuit.
Is this a good idea?
The problem is when the op amp is connected to the relay it seems to 'draw' the output voltage from 12V to 7V. So now the relay is not switching.
I tried to use a 6V relay, but with no luck. the voltage then dropped to about 1V
Any feedback would be appreciated.
Thanks
