Sterling Power 12V 40A Pro Charge Ultra Battery Charger PCU1240

Sterling Power’s line of 12V 10-60A / 24V 20-30A Marine Grade, Power Factor Corrected Battery Chargers set a new standard of what you should expect from your battery charger when it comes to features, performance & price. As these chargers are digitally controlled it is possible to simply add these chargers in parallel or series to achieve larger voltages or currents.
Sterling Power’s years of experience in the battery charging industry has provided the insight to include everything we could possibly think of and combine it all into the Pro Charge Ultra. This exceptionally efficient power factor corrected battery charger runs on any global AC power source between 90-270 volts (freq 40- from 70Hz). The unit requires less input power, liberates less waste energy and is still remarkably lightweight with a small footprint.
The Pro Charge Ultra range of battery chargers are among the worlds most efficient chargers, thanks to ‘active power factor correction’. This feature means they are rated over 90% efficient compared to 65% on chargers without.

These award-winning chargers feature a 32 LED front panel showing charging profile statuses and output power as well as providing the user with a voltmeter and ammeter.

There are 11 pre-programmed charging profiles for calcium, sealed/flooded, Gel and AGM batteries. Users are also able to customise the programme to have their own tailor made profile.

Batteries are kept rejuvenated as the Pro Charge Ultras include an automatic desulphation mode.

The Sterling Power Pro Charge Ultra Chargers are fitted to more new boats than any other charger in the world.

They have been UL 1236 SB listed which is the highest build standard and include a temperature compensation sensor for maximum reliability and safety.
