Programmable Bidirectional AC Power Supply Model 61800 Series

Programmable Bidirectional AC Power Supply Model 61800 Series

Grid simulator capable of testing PCS, smart grid, and EV-related products, 100% bidirectional AC power supply supporting reverse power flow.

Currently, there is growing demand in the market for PV inverters, wind power generation systems, and other renewable energy sources. This demand requires various standard specifications such as IEEE 1547 / IEC 61000-3-15 / IEC 62116 for on-grid products, as well as appropriate and safe verification testing. The 61800 series is a bidirectional regenerative AC power supply that utilizes four quadrants. It meets a wide range of needs not only in product development but also in quality assurance and production. The 61800 series adopts full four-quadrant regenerative operation, making it a programmable AC power supply designed for testing general electrical products such as home appliances and industrial electronic devices. Additionally, it has been designed to simulate the characteristics of the grid, such as power conditioners (PV inverters), inverter power supply, and UPS. It can support both sink and source applications from the unit under test (UUT). In this case, the source current detection circuit of the UUT senses surplus power, which is then reused (regenerated) back into the grid.

【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.*
