Waterproof IP68. The converter is cast with epoxy resin waterproof and allows individual use, e.g. outdoors as a power supply for lighting or at sea, installed in boats.
Robust | By casting the electronic parts in the housing, enormous stability and resistance to vibration is achieved. A long service life and integrity are guaranteed.
Protection circuits | Overvoltage protection, reverse polarity protection, short circuit protection, overload protection and overheating protection ensure safety. Please refer to the data sheet of the respective device.
Performance: When selecting the device, pay attention to enough leeway in the voltage range up and down. Schedule buffer upwards at the current due to increased initial loads.
Not suitable | QC(Quick Charge) is not possible with these dc-dc converters. This requires communication between the charger and the terminal.
Manufacturing | By producing in an ISO 9001 certified company with functional tests and quality checks, we can minimize defects and optimise workflows and costs.
Cooling | The module can perform the maximum output current without active cooling and thus works silently. Depending on the load, heat generation can be expected.
Connection | The DC/DC converter comes with tin-plated, open ends. The cross section and the cable length can be found in the respective data sheet.
Caution | Never operate electrical devices permanently at the power limit as this can lead to damage. Pay attention to intact wires and the correct polarity of the connections.
Areas of application: the modules are widely used in the areas of cars, photovoltaics, industrial plants, trucks, boats, agricultural machines, camping, mobile facilities, hobby and DIY as well as home and garden.
