Over voltage protection circuit design
Budget: $30 – $250 USD
I need an over voltage protection circuit designed, which needs to cut off the input source when it reaches 59vdc.
Max current of power circuit is 3amps.
This is to protect the 12v and 5v power regulator circuits.
During normal operation, the input source is between 40-59vdc. There are situations that arise where the input voltage may rise to 160vdc for about 3-4 seconds, hence the requirement of over voltage circuit to protect the regulators. The circuit must fit in an existing pcb design.
Parts must be available in Jlcpcb.
