The SSU2-50/S is compatible with any 12V automotive battery, including AGM, GEL and LiFePO₄ battery types, making it suitable for modern vehicle showrooms.
-
The SSU2-50/S uses automatic current sensing to detect when a vehicle’s battery needs support.
When power is required, it delivers a stable, regulated 13.4 V output at up to 50A to sustain accessory loads and offset parasitic drain.
When support isn’t needed, the unit remains idle, minimising noise and power use, helping to preserve battery condition and ensure vehicles consistently start and present well.
