A DC converter is an electronic circuit or electromechanical device that converts a source of direct current (DC) from one voltage level to another. It is a type of electric power converter. Power levels range from very low to high. DC converter is divided into step up DC converter and step down DC converter.
DC to DC converter is used in portable electronic devices such as Car black box,car GPS,cellphone and Camera charging, which is supplied with power from batteries primarily. Such electronic devices often contain several sub-circuits, each with its own voltage level requirement different from that supplied by the battery or an external supply.Additionally, the battery voltage declines as its stored energy is drained.Switched DC to DC converters offer a method to increase voltage from a partially lowered battery voltage thereby saving space instead of using multiple batteries to accomplish the same thing.Most DC to DC converter circuits also regulate the output voltage. DC DC converter with Mutiple Protection Function. Reverse polarity protection, over current protection, over temperature protection, short circuit protection. Synchronous rectification, the conversion rate is 95% or more, lower heat and long working time.
How to choose a DC converter?
To purchase a DC converter, we should consider the material of the DC converter cable and the automatic protection over voltage function.The Features of DC converter produced by Kuncan Electronics:
1. Auto protect over voltage, over current, over temperature, short circuit, ,can work in normal condition when restored.power-off protection: 11.5v-12v
2. The part of PCB board is moulded by PVC,it is hardto damage.
3. usb charging cable with pcb board for black box
4. all the cables are 100%tested.
