Special positive regulated charge controller for charging 2 lead or AIRBATT-LiFePO4 batteries in gliders.
The SLRK 1252 has 2 separate outputs for charging 2 batteries. The regulator is protected against overload and reverse polarity. The charging status is indicated by a multi-function LED. The charge controller can be used as a successor to the OS4 as well as limited for OS2 from Strobl-Solar.

Technical features:

• very small 67x58x22mm LxWxH
• maximum charge current solar module 8A
• maximum input voltage 30V
• charging voltage Uo 14.8V
• standby voltage 13.8V
• no own 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 with Strobel-Solar solar cells in aircraft
• replaces Strobl-Solar charge controller OS4 (limited for OS2)

Function indicators by green LED light:

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