昭和電子工業 List of Products and Services

The "S-25N5 type" is a phase detection relay used in self-owned AC substations, which measures the phase difference between different power sources and the voltage vector difference. When the set conditions are met, the contact output circuit turns ON and outputs the results. It has a serial transmission output function (USB connection) that allows the output of each power supply voltage, voltage difference, and phase difference to a computer as needed. 【Features】 ■ Measures the phase difference and voltage vector difference between different voltage sources in substations, etc. ■ Equipped with a serial transmission output function, allowing data to be output to a computer as needed. *For more details, please refer to the PDF materials or feel free to contact us.

The "S-25P2 model" is a synchronous tester that has the capability to output phase difference in BCD code for monitoring and control terminals. In self-sustaining AC substations and similar facilities, it measures the phase difference between different power sources as well as the voltage vector difference. When the set conditions are met, the contact output circuit turns ON and outputs the result. 【Features】 ■ Measures phase difference and voltage vector difference between different power sources ■ Continuously displays the phase difference value on the main unit ■ Outputs in BCD code to monitoring and control terminals *For more details, please refer to the PDF document or feel free to contact us.
