Very small solar charge-controller for charging 1 or more Lead-Acid or LiFePO4 batteries in the trailer.
The SLRK1252 has 2 separate outputs for charging 2 batteries as well as a special program to avoid overcharging the batteries.
It is also protected against overload and polarity reversal.
The charging status is displayed via a multifunction LED.

The charge controller can be used as a successor to OS4 and to a limited extent for OS2 (from Strobl).


Technical features:
- No self-consumption (reverse current).
- Automatic overcharge protection.
- Optimal full charge and charge retention.
- Short-circuit proof.
- Reverse polarity protected.
- High charging efficiency.
- Status displayed by LED.
