The "High Range High Performance Charge and Discharge Device" is a charging and discharging device that uses a dropper-type power supply and subdivides the current range into eight ranges. This allows for more accurate battery cumulative capacity measurement than before. Additionally, during current attenuation under low voltage control, the current range can be automatically and seamlessly switched, enabling measurements without compromising accuracy or resolution even during constant voltage control from high currents. Furthermore, it is also capable of measuring leakage current during constant voltage charging. 【Features】 ■ Voltage and current accuracy of ±0.02% due to the dropper-type power supply. ■ Accurate battery cumulative capacity measurement with eight ranges. ■ Independent control of 6 channels per case. ■ Current auto-range function with semiconductor switching (range switching time approximately 20 milliseconds). ■ Capability to measure leakage current during constant voltage charging. *For more details, please refer to the catalog or feel free to contact us.

• Electrical Instruments/Electrometers

The "EF-7100P" is a portable charge and discharge power supply with automatic current range.
