The Sterling Power PCU1240plus is a 12V 40A mains battery charger from the Pro Charge Ultra Plus range — a compact, switch-mode charger built to keep 12V banks properly topped up from shore power or a generator. It delivers a full multi-stage charge rather than a crude constant voltage, so lead, AGM, gel, and lithium banks are charged correctly and held at the right float.
Pro Charge Ultra Plus models add selectable battery profiles (including lithium), advanced diagnostics, and remote-control capability via the PCUR remote.
