High battery charger. 3 - Supply voltage 110 and 230 at 50-60 Hz. 12 V-60 amp models all other types in proportion. Input voltage range 90-270 volts 40-70 Hz. Efficiency 89.4%. Current at full load (110 / 230v) 9.8 / 4.6. Noise and Voltage Wave (R.M.S.) 14mv. Sterling ProCharge Charger Features: 11 pre-programmed Lifep04 charging curves. 1 custom setting, can be set on the charger - no need to use the computer. 2 x digital measuring instrument - voltmeter, ampermeter. 1 x power meter - displays power reserve on the device. The new synchronized rectifier - compared to the diode - is 10% more efficient. High voltage de-sulphation cycle. Battery rehabilitation program. The multi-speed cooling fan reduces unnecessary noise at low loads, new extremely efficient cooling fans ensure reliable operation even at high temperatures (40-50 ° C). Primary (processor-controlled) and backup, emergency secondary protection (analog-controlled) overvoltage. 32 L.E.D. information panel. Internal System Check. Remote control. Small size and low weight. It contains a battery temperature sensor. As with all marine chargers, all non-ferrous materials are used.
