Multiple protections:Overheat protection: The charger will close automatically without current output for protective when its temperature is over 105, and when the temperature is decreased about 80 or power supply is shut down for 10 minutes, charging process can be resumed.Short circuit protection: In case of accidental short circuit, the charger will close automatically without current output, and beep for alarming. Once correctly connected, charging process will be resumed.Reverse connection protection: Whenever positive poles and negative poles of the charger and the battery are not connected correctly, the charger will close automatically without current output, and beep for alarming. Once correctly connected, charging process will be resumed.Low voltage protection: When single cell voltage is 1.5V, the charger can not be started up, and beep for alarming. This mechanism is to avoid possible damages caused up by voltage discrepancy between the battery and the charger.Input Voltage: 110-250VOutput voltage: 12V\/24VCurrent:15A for 12V,18A for 24VSuitable capacity: 30-200AHPower:600WFrequency: 50-60HZLength of output wire:65cmLength of input wire:125cmDimension: 68x34x49cmGross weight:1.9 kgApplication: best suitable for30-200AH lead acid batteries(including wet and dry)Charging operationStep 1, Examine and make sure rated voltage of battery is conforming to output voltage of charger., Connect correctly the charger and the battery.Step 3, Examine and make sure mains supply voltage is conforming to input voltage of the charger.Step 4, Connect mains supply and the battery, watch to see if the indicator is on and the cooling fan is working when charging.Step 5, if the charger refuse to work, turn off mains supply immediately and check all the connecting cables between mains supply, the battery and the charger.Plug Type: EU Plug, it applies to Indonesia, Germany, France, Spain, Italy and so on.Colour: redMaterial: metalPackage Contents:1 * Battery ChargerOnly the above package content, other products are not included.Note: Light reflection and different displays may cause the color of the item in the picture a little different from the real thing.
