[Discontinued] Step-up and Step-down Charging Charger "DC-1220SPa"
The input can use both DC 12V and 24V systems, as well as PV panels, and it can boost the voltage to charge the sub-battery even when the main battery is low.
●This charger is a device that charges the DC12V sub-battery from the main battery used for engine start and PV panels installed in the vehicle. It can charge by stepping down/up from a wide range of input voltages, and when using a 12V main battery, it can reduce the load on the vehicle's alternator by also using PV panels for input. ○Charges the DC12V sub-battery from DC12V to DC24V vehicles ○Due to the boost function, it can charge from a lower voltage battery to a higher voltage DC12V battery ○Compatible with lead, AGM, and lithium-ion batteries ○Charging control from PV panels is achieved with MPPT technology for high efficiency ○Soft start function when the sub-battery voltage is low ○Charges from the main battery in conjunction with the vehicle's engine key ○Input low voltage output cutoff and automatic recovery function ○Four LEDs allow confirmation of operating status, charging status, output voltage level, and input voltage level ○Low noise equivalent to VCCI Class B ○Can be placed vertically using the included bracket as well as horizontally ○With the optional temperature sensor, it has a function to detect the temperature of the sub-battery and cut off the output.
