Special plus regulated charge controller for charging 2 lead or LiFePO4 batteries from AIRBATT in the trailer.
The SLR2125 has 2 separate outputs for charging 2 batteries and a special programme to avoid overcharging the batteries in the glider trailer. The controller is protected against overload and reverse polarity. The charging status is indicated by a multi-function LED. The charge controller can be used as successor of the OS3 as well as limited for OS1 from Strobl-Solar.

Technical features:

• maximum charging current solar module 8A
• maximum input voltage 30V
• charge voltage Uo 14.8V
• standby voltage 13.8V
• no self-current consumption (reverse current)
• automatic overcharge protection
• optimal full charge and charge Retention
• high charging Efficiency
• function indicator by LED
• short-circuit-proof
• reverse polarity protection
• Special AIRBATT charging characteristic (IUoU)
• for charging in the trailer
• replaces Strobl-Solar charge controller OS3 (restricted for OS1)

Function indicators by green LED light

• off/off: no battery(ies) connected / solar panel does not supply enough voltage
• flashes/flickers: battery(ies) charging / charging
• lights up permanently: full charge voltage reached / standby voltage
