The DGR3680 is a multi-channel switch system designed for switching units. When paired with a rapid control module, it enables precise and high-speed channel switching control. This system is suitable for multi-channel switching applications in battery manufacturing and electronic circuit production.
It supports integration with battery testers, micro-ohmmeters, digital multimeters, and other instruments to perform tests such as internal resistance and voltage measurement between battery electrodes, edge voltage detection, and low-resistance measurement. The number of connectable channels for the device under test can be selected from 24, 48, or 72 channels, allowing flexibility based on actual requirements.
