Votronic PFPN 1204 On Board B2B Battery Charger – DC/DC Converter for 12V Systems
The Votronic PFPN 1204 is a DC/DC on-board battery charger designed to charge 12V batteries from a 12–24V DC input source. It converts higher-voltage DC power — such as from a vehicle alternator or a 24V solar setup — down to a stable 12V output suitable for standard lead-acid and AGM batteries.
Converts 12–24V DC input to a regulated 12V output for reliable battery charging
DC/DC converter design ensures galvanic isolation and stable charging voltage
Compact, lightweight unit at 0.27 kg — easy to install in confined engine compartments
24-month manufacturer warranty provides long-term reliability and investment protection
What makes the Votronic PFPN 1204 stand out
Unlike simple voltage regulators, the PFPN 1204 actively manages the charging profile, delivering a consistent 12V output regardless of input fluctuations between 12V and 24V. This makes it suitable for vehicles, boats, and off-grid setups where the primary power source voltage varies.
Ideal for
Boat owners and caravan users who need to charge a 12V house battery from a 24V alternator or dual-battery system. Also suited for solar installations with a 24V battery bank that requires a 12V auxiliary charging path.
Application of Votronic PFPN 1204
Connect the input side to the 12–24V DC source (alternator, solar charge controller output, or auxiliary battery)
Connect the 12V output to the 12V battery being charged
The charger automatically regulates the output voltage to 12V — no additional configuration required
