Quick Battery chargers AUTOMATIC 110-250 VOLTS Three stage IUoU battery charging, Multiple outputs in order to charge more groups of batteries (internal battery isolator diodes), Charge selector for liquid/gel electrolyte batteries, Integrated fuses inside the battery chargers (one for each output), Able to provide full output power with low supply voltage. Can use the battery charger as a power supply without batteries, Low residual fluctuation on output (ripple lower than 30 mV RMS), Power factor (cos) equal to 1, Compatible with every kind of generator, Can work in a wide range of ambient temperatures, Variable speed for the cooling fan, Automatic and manual half power mode, Case constructed in stainless steel, aluminium and Cycoloy. All chargers are automatic 90-250V. Hz 46 - 66. 3 Step automatic charge BULK phase (constant current) ABSORPTION phase (constant voltage) FLOAT phase (maintenance) Universal AC Network: Protections: ò Reverse polarity (with internal fuses) ò Overload ò Output short
