Hi..
Help me design a circuit to meet the following requirement.
I am driving a transformer coupled load through a Phase angle controlled thyristor power pack (single phase). The mains is 240 volts (R phase and neutral) to the Power pack. The output of the thyristor is controlled (0 - 220 v) via a potentiometer of
10k ohm. The output of the thyristor is put to the primary of the step down transformer.The current flowing from the output of the thyristor and the primary of the transformer with the help of CT (50 / 5 ratio).
I now need a circuit to trigger a relay with reference to a set point (to be adjustable from
0.5 to 5.0 amp via a potentiometer / trimpot). Display of the current would be a parameter of luxury.Can some one please guide with their response on snipped-for-privacy@gmail.com
thanks
