Technical InformationRated input voltage90-264 VAC, 50/60 HzBattery type12V nominal 3-cell 10.8V or 11.1V lithium ion or lithium polymer batteryInput Frequency50-60 HzBattery voltage12 volts nominalBattery size3 AH to 30 AH packsCharging current3.3Amps or 3300mA peak chargeCharger typeConstant Current/ Constant Voltage precision chargerCharging algorithmThis is the "European" charge algorithm that does not float charge the battery at the last stage, but still keeps it maintained. (see the graph below)Constant current/constant voltageStage 1 slow start, precharge function for deeply discharged packsStage 2 bulk charge stage. 3.3 amps is applied to the battery until the voltage rises to 12.6 voltsStage 4 constant voltage state until the charge current falls to 400mAStage 5. The charger turns off.StyleDesktopOutput power42W peakOutput voltage12.6 volts maximum during chargeWeight275 grams, 0.275 kg, 0.6 pounds, 9.7 ozCoolingNatural convection, no fanOutput options included5.5 mm OD x 2.1 mm ID barrel, center positive More barrel connectors available separately, see belowEfficiency>80%Size120 x 67 x 41 mm, 4.7 x 2.6 x 1.6 inchesVibration, Impact5mm, 50Hz, 600 Seconds, 1 meter drop 3 timesEnvironment-20°C to 50°C operating, -40°C to 70°C storageProtectionsOver Voltage Protection, Output current protection, reverse polarity protection (auto-clearing), short circuit protection (auto-clearing)SafetycUL, UL, CE marked, designed to EN60950, GB4946, UL1950, certified and marked cULMTBF30,000 hours by MIL-STD calculationHiPot, ESDHi-Pot 3000 V, 1 minute, ESD 8000VLED IndicationsPower on, but no battery connectedPower LED redSlow startThe lowest green light is the only one on.ChargingCharging lights lit to show the state of chargeChargedAll four green LEDs are onReverse polarity, or shorted outputAll lamps flashNo battery connectedRed light is on, but no green LEDs
