АМ4080 is a digital measuring, fully programmable device from the 4080 series, designed on the basis of microcontrollers. It measures current up to 10 A AC/DC (it can measure any other current by connecting an external shunt resistor or current sensor).
AM4080 can be directly connected to a current transformer with a maximum secondary current of 10 AAC. The device has potential-free contacts for remote signalisation if measured current goes out of a certain specified range (option “R”). It is designed to be mounted on boards in control rooms of electrical substations.
