Function Description:

1. Calculation of voltage percentage: battery voltage/(upper limit voltage-lower limit voltage)
2. Button function:
UP button: Short press to switch display% and time, long press for 5 seconds to switch mode, charging mode: IN, discharging mode: OUT
SET button: short press to view the currently set parameters; long press SET button to enter the parameter setting interface, set UP: voltage upper limit, dn: voltage lower limit, OP: conduction time, dOP: delay conduction time (0-999 seconds) , There is FOP in discharge mode: forced conduction time (0-10 seconds)
DOWN button: Short press to turn off/on the relay enable (emergency stop function) after it is turned off, the LCD display is OFF, and the relay is disconnected.
Long press the DOWN button to set the status of the LCD backlight. L-P: OFF, the backlight is always on, ON: the backlight will automatically go out after 5-10 minutes; any key to wake up after it goes out.

Note:

This product is a simple voltage controller, which uses a relay to turn on and off the output. It only functions as a switch and cannot be transformed.

Discharge mode OUT:

By setting the upper limit voltage UP and the lower limit voltage dn; when the battery voltage ≥ the upper limit voltage UP, the relay is turned on and starts to discharge; when the battery voltage ≤ the lower limit voltage dn, the relay is disconnected to complete an automatic discharge function; the relay is turned on and OUT flashes, Indicates that it is discharging.

Charging mode IN:

By setting the upper limit voltage UP and the lower limit voltage dn; when the battery voltage ≤ the lower limit voltage dn, the relay is turned on, and the charger starts to charge the battery; when the battery voltage ≥ the upper limit voltage UP, the relay is disconnected to complete an automatic charging; the relay is turned on, IN flashes, indicating that it is charging.
