【Technical Information】What is the difference between direct current power supply and alternating current power supply?

【Technical Information】What is the difference between direct current power supply and alternating current power supply?

Introduction to the power supply "DC" converted by dry batteries and AC adapters, and the power supply "AC" provided by power companies.

Here, we introduce the differences between direct current (DC) power supplies and alternating current (AC) power supplies. Direct current (DC) is a power supply converted from sources such as dry batteries or AC adapters. It maintains a constant voltage in the positive direction over time. Alternating current (AC) is the power supply provided by power companies, and the 100V power supply obtained from wall outlets is a single-phase AC supply with 50Hz in the Kanto region and 60Hz in the Kansai region. The voltage alternates between positive and negative at a constant frequency over time. **Features of Direct Current (DC) Power Supplies** - Power supply converted from dry batteries or AC adapters - Maintains a constant voltage over time - Positive voltage *For more details, please refer to the PDF document or feel free to contact us.*
