Product details

The high-quality PRO CHARGE ULTRA 12 V / 50 A charger is packed with innovative features that allows up to three batteries to be optimally charged for long battery life.

Worldwide area of application
You can either supply the device with a voltage ranging from 80 - 270 V AC and 40 - 70 Hz or with a DC voltage of 130 - 320 V DC. The PRO CHARGE ULTRA can be used worldwide and easily powered by generators.

Suitable for a wide range of battery types
The Pro Charge Ultra charger has 11 pre-programmed charging characteristics for the following battery types: Gel, AGM, maintenance-free or open, lead-acid batteries, calcium, and even LiFePO4 batteries.
If your battery is not one of the batteries listed, you can easily set and save an individual charging or trickle charging voltage characteristic via the front control panel.

Automatic desulphation / equalization
A further innovative feature is the automatic desulphation / equalisation. Every 7 - 10 days, a desulphation / equalisation and anti-stratification program is performed which prolongs the longevity of your battery.
Integrated security system

Integrated safety system
Function and charge are continuously monitored by a processor. In the event of a malfunction or faulty charging, the device switches off automatically and the panel informs of the corresponding fault. In the event of a processor error, a further safety system shuts down the unit.

Performance control and status monitoring
The digital panel on the front of the charger allows you to quickly and easily check that the battery is charging correctly and without errors. You can also check the performance of the charger.
The LED bar indicates whether the device is operating at maximum power or at which percentage power. A further 32 integrated LEDs provide information on charging and device status and on the battery type set.
