AC synchronous time transmitter P18-NTPAC 1 piece

Automatically adjusts with AC power. Simple and compact radio clock time transmitter. This is a radio-controlled clock transmitter that keeps time based on an AC signal obtained from household AC 100V. This unit operates by adjusting the gain and loss of its internal clock, focusing on the fact that the AC 100V power supply frequency (50Hz/60Hz) is always controlled so that no cumulative error occurs. First, set the time using the web browser app, and then the internal clock will be adjusted using an AC signal. This technology is particularly effective in buildings where it is difficult to receive standard radio waves, and especially in basements of buildings where there is no Internet connection, expanding the possibilities for using radio-controlled clocks. The maximum transmission distance to radio-controlled clocks is 10m.

A normal AC adapter (DC output) will not function. The automatic synchronization function of this unit depends on the accuracy of the commercial power supply (100V AC). Neither the power company nor Kyoritsu Electronics Industry Co., Ltd. guarantees that the synchronization function will function correctly when using an AC power supply. The automatic synchronization function of this unit depends on the accuracy of the commercial power supply. The commercial power supply constantly adjusts its frequency while outputting, so over the long term the accumulated error approaches zero, but when you set the time on this unit, there will be a momentary deviation from the ideal value. Temporary time discrepancies may occur during special periods of power demand, such as the end of the year, the New Year, the Obon holiday season, or other weather events (heavy snowfall or abnormally high temperatures) or social events (such as a sports championship or a hostage situation) that the power company could not predict. If you notice that the time is incorrect, we apologize for the inconvenience, but please readjust the fractional seconds using the procedure in the instruction manual "Displaying and clearing fractional seconds" or set the time again. In environments that are cut off from large-scale power distribution networks, such as remote islands, and environments where the power frequency is generated by private generators or AC inverters, the effect of eliminating cumulative errors caused by the synchronization function may not be achieved. Please note that the appearance and specifications may change without notice.
