Product parameters:
① Voltage range:DC 0-420V (DC5V independent power supply)
Capacity range: 0-99999AH
Current range: 0~30A/0.1~100A/0.2~200A/0.3~300A/0.4~400A/0.5~500A/0.6~600A(optional)
② Support the modification of circuits that require additional relays to be fully charged and fully discharged, which can protect the battery;
③ Support low-voltage, over-voltage, over-Power prompt or power outage (when adding 5V relay circuit); Support bidirectional current testing access,After the line, there is no distinction between the direction of current!
u2463 Support shunt selection: 100A/200A/300A/400A/500A/600A (optional)
Attention:
This product is a bidirectional current test. When discharging, the current displays a "-" symbol. When charging, the current displays a "+" symbol. The capacity test is cumulative, and you need to hold down the "+" and "-" keys to reset zero the capacity. Enter charging or discharging to test the capacity, and the test result is the discharge capacity or charging capacity!
