Fully complete 3-stage management, three load working modes design, easy to satisfied with your operating demands.

Features:
​The build-in industrial main control chip can automatically adapt to the input voltage of 12 volt or 24 volt.
Large LCD display with and discharging current display, cumulative generations and discharge query, display and control delay display, and etc..
The and discharge parameters are adjustable, with -off memory and other functions.
The dual USB output, with a maximum current of 2.5A, supports mobilephones with the iOS system.
Equipped with PWM mode, fully complete 3-stage management, charges a while, stops a while, small current charges when nearly full.
Build-in short-circuit protections, open-circuit, reverse connection, over current, all are self-recovery type, no damage to the controller.
-backflow circuit design with low heat production.
​Discharge recovery voltage function: after discharge protecting, the voltage rises to the recovery voltage, automatically opening the output.
Discharge cut-off voltage: when the is discharged to the voltage, the load is turned off to the and prevents the from being damaged by over-discharge.
Three load working modes design, easy to satisfied with your daily demands:
【24H】 load normally open mode (except under voltage)
【1-15H】the load is turned off when under control and 1-15hours timer (automatically turn on the at night for 1-15 hours and then turn off)
【OH】pure control mode (turn off in the day; turn on at night)
