240V AC mains undervoltage and overvoltage cutoff circuit

Job ID: 36999769

Budget: ₹1,000 – ₹2,000 INR

This is mainly a basic circuit design.
I want an undervoltage and overvoltage cutoff circuit for 240V AC mains.

The functional requirements are such:

Min Voltage: 100V
Max Voltage: 290V
Max Power drawn: 300W (for eg. 1.2A@250V, or 3A@100V)

The input circuit should be cutoff outside the min-max voltage range (variable).

Also, it should be a non-relay cutoff. So you can think of triacs or mosfets or anything else.

I want the circuit alongwith the Material list (eg. 12V transformer, diodes etc.).
