It contains an inverter that is capable of increasing and decreasing the input voltage to create the optimum voltage for charging the external battery.\u003cbr\/\u003eIt connects to the primary starter battery and exploits the potential of the vehicle's alternator even when charging of the starter battery is restricted to reduce emissions.\u003cbr\/\u003eSolar panels can also be connected to the charger to charge the external battery when it is not being charged by the alternator.\u003cbr\/\u003eAn automatic mains charger (AC-DC) can also be connected to the terminals of the external battery without disconnecting the DC-DC charger.\u003cbr\/\u003e\u003cbr\/\u003eTechnical parameters:\u003cbr\/\u003e\u003cbr\/\u003eInput voltage: 12.4-16VDC.\u003cbr\/\u003eInput voltage from solar panels: 16-25VDC (PV panels with system voltage 12V connected in parallel must be used)\u003cbr\/\u003eMax. current from solar panels: 40A (max.500W), PWM controller\u003cbr\/\u003eSystem output voltage: 12VDC\u003cbr\/\u003eCharging voltage: 14-15.4V depending on the secondary battery used (Pb or LiFePO4)\u003cbr\/\u003eHolding voltage: 13.5V (only for Pb battery variants)\u003cbr\/\u003eCharging current of secondary battery: max 40A\u003cbr\/\u003eThree-stage intelligent charging of the secondary battery\u003cbr\/\u003eBattery types connected: Lead Acid, AGM\/GEL, Calcium, LiFePO4\u003cbr\/\u003eDimensions: 210x140x40mm\u003cbr\/\u003eNet weight: 1.1kg\u003cbr\/\u003e\u003cbr\/\u003eCharging Priority:\u003cbr\/\u003e1) 12V voltage at the \"ACC\" input (ignition on, preferably when the engine is running):\u003cbr\/\u003eIn this mode, the external battery is only charged from the DC Input, i.e. from the vehicle's on-board mains. Charging from the photovoltaic panels is blocked. The DC input voltage must be \u003e12V\u003cbr\/\u003e2) The \"ACC\" input is not 12V (ignition off or engine not running mode)\u003cbr\/\u003eIn this mode, the external battery is charged preferentially from the PV panels. If the panels are out of service (Uoutput \u003c16V), then the charge is taken from the DC Input if a voltage \u003e13VDC is available. Thus there is no risk of discharging the primary battery.\u003cbr\/\u003e\u003cbr\/\u003eRemark:\u003cbr\/\u003eIt is also possible to connect a standard mains charger, which is part of the caravan or trailer on-board network, to the secondary battery terminals. Charging of both connected chargers is then governed by the terminal voltage of the secondary battery being charged, so there is no need to worry about damage to the secondary battery.","brand":"CARSPA","offers":[{"title":"Default Title","offer_id":53615601680722,"sku":"04240695","price":122.57,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0954\/9624\/1490\/files\/04240695.jpg?v=1780302549","url":"https:\/\/tipa.eu\/en-en\/products\/dcdc-charger-carspa-dcds40-v-2-12v40a-with-solar-input","provider":"TIPA","version":"1.0","type":"link"}
