KM-20 is a device that measures and displays both voltage and current in a single unit. It is equipped with voltage protection relays and current relays to protect against undervoltage and overvoltage conditions. The unit can also store the maximum peak values of voltage and current, allowing these data to be used for system analysis and performance evaluation.
