Features:
1. It adopts a three position bright LED digital tube display and a card slot installation method.
2. Accurate measurement of DC voltage, with flashing alarms for upper and lower voltage limits.
3. Multiple modes can be combined according to the upper and lower limits of the set voltage, various delays, timing, and timing cycles.
4. Various mode setting parameters can be saved after power off, and the last mode execution can be resumed after power on again.
5. Widely used in battery charging and discharging control, automotive battery control, DC motor control, and overvoltage/undervoltage protection.
