set time.
●
Time Switch Mode
Under this mode, loads can be only powered during the set time.
NOTE:
Time is 24 hours Time Mode which just the one shown on the LCD
A new set time will be only adopted on the morrow if user changes the time that is
already set.
If the turning-on time is set before current time, KC3 can only power the loads at the
same set turning-on time but on the morrow.
If the turn-off time is set before current time or before turning-on time, KC3 only
stops powering the loads at next set time.

Manual Switch Mode
Under this mode, only users can control the turning -on and turning –off, see details in

Battery Charging Management
Management proceeds Precharge, Voltage Limit, Float Charge according to different Initial
Status of Batteries.
Precharge works after deep Discharge, in case of a shock to the batteries from Initial Impact
Current.
Efficient PWM begins to charge after a certain charge from the battery, and turns to Voltage Limit
Charge when goes into the limited line.
Float Charge begins and keeps its status at the end of the process. “Full” LED turns on.
Float Charge will keep working to recover the loss from self-discharge of the batteries.
Recovery of batteries’ temperature is functional at this same time.
Voltage Valve’s Value of each reference point to be recovered by this function.
Batteries’ Valves’ Values falls down when temperature gets up.
Too high Charging Voltage will lead harmful gas and water missing of the batteries when
temperature gets too high.
And it will be undercharge to the batteries when too low temperature.
Temperature Compensation will automatically adjust the Charging Voltage at that moment.
The range of Temperature Compensation is -20
℃
--50
℃
, it is not available when out of this
range. It keeps Final Charging Voltage never exceeds to the one required.
Efficient PWM mode keeps batteries working at the best status, which much extends their lives.
