The Victron Energy Smart IP43 Charger 12/50(1+1) 120–240V, manufacturer part number PSC125051095, is an advanced AC-to-DC battery charger designed for compatible nominal 12V battery systems. Combining a powerful 50A house battery charging output, a separate auxiliary starter battery charging output, built-in Bluetooth Smart connectivity, and Victron Energy's adaptive six-stage charging technology, this charger provides intelligent battery charging for marine, recreational vehicle, off-grid, and backup power applications.

The charger supports a wide range of AC supply conditions, allowing it to operate from compatible utility power, shore power, and generator sources. Its intelligent charging electronics regulate the DC output according to the selected battery charging profile and operating conditions.

Important: The PSC125051095 is an AC-powered battery charger, not a solar MPPT charge controller or inverter. The AC mains cord must be purchased separately. An AC inlet retaining clip is included.
