About This Product
■Summary
NA2201 is a digital earth leakage detection IC with overvoltage detection/DC detection using CMOS process. The analog signal obtained from the ZCT (zero layer current transformer) is converted into digital data by the built-in ADC, and data processing is performed based on the earth leakage detection conditions based on the set trip level.
As a result of data processing, if it is determined that there is an earth leakage, a one-shot pulse is output to the SCRT terminal and the externally connected thyristor is turned on. The overvoltage detection function supports overvoltage detection (AA neutral wire open phase protection).
Also, using the same function, it receives a DC signal from the flux gate section, checks the threshold value according to the signal size, and performs DC detection. The delay time can be set independently for two systems: earth leakage detection and overvoltage detection.
