1. US20100188785 - Device for monitoring and protecting the power supply of electrical equipment and method for implementing said device

A device for monitoring and protecting electrical equipment, placed in series on a power supply line between an electrical power source and the equipment, includes:

• • at least one voltage regulator for regulating a power supply voltage of the equipment,
  • at least one current limiter, coupled to the voltage regulator to reduce the power supply voltage of the equipment if a power supply current absorbed by the equipment exceeds an upper operating value,
  • at least one crowbar short-circuit device, adapted to be activated when the input voltage exceeds a safety limit value, higher than the upper operating value, and to cause a fuse placed in series between the power source and the equipment, to blow, and calculating and storage elements adapted to generate a clock and to log a date of occurrence of a fault and the operating parameters of the power supply for the equipment in a non-volatile memory.
