In photovoltaic energy storage and other application systems, the ONCCY EDS1 plays a critical role. It is suitable for power systems with a rated voltage of 1200V DC and below, and a rated current of 32A and below. This product boasts excellent electrical performance and is designed for infrequent switching operations. It can simultaneously disconnect 1 to 2 Maximum Power Point Tracking (MPPT) lines, effectively enhancing system operational efficiency. In high-voltage DC transmission and distribution systems, the ONCCY EDS1 is particularly suitable for precise line isolation. For example, in solar power generation scenarios, it reliably disconnects the high-voltage DC current between the solar panels and the inverter, ensuring stable system operation.
